Tamron SP 150-600mm F/5-6.3 Di VC USD Lab Test Review

June 2014 | By Andy Westlake

The Tamron SP 150-600mm F/5-6.3 Di VC USD is one of a select group of supertelephoto zooms for full frame SLRs that reaches or exceeds 400mm focal length, while still being reasonably portable. This type of lens is the tool of choice for small or distant subjects when large heavy primes are impractical, ranging from birds and wildlife, through sports, to aircraft and the like. The Tamron's trump card over its closest competition (the Sigma 150-500mm F5-6.3 DG OS HSM and the various 400mm telezooms from the camera makers) lies in its longer focal length - at 600mm full zoom, it'll let you get your subjects that bit larger in the frame.

Tamron announced the lens at the end of 2013, which means it's the most modern in its class, and therefore, in principle, has the most up-to-date optics. It includes several features that are more-or-less essential to this type of lens - optical image stabilization (which Tamron calls Vibration Compensation, or VC for short) and an UltraSonic Drive motor for fast, silent autofocus (hence USD). It also comes with a collar for attachment to a tripod or monopod; at almost 2kg (4.3lb) in weight, you're probably not going to want to shoot it hand-held for long.

One point worth noting is that the lens has a decidedly slow maximum aperture, starting at F5 and dropping to F6.3 at full telephoto. This is the price you pay for getting such a long zoom range at all; Sigma's 150-500mm offers the same aperture range, and the camera manufacturers' closest equivalents tend to max out at 400mm F5.6. However with the high-ISO capability of modern sensors, this is no longer so limiting as it might have been just a few years ago.

The Tamron isn't just for full frame cameras: it can also be used on APS-C SLRs, on which if offers a huge 225-900mm equivalent range. If you're thinking of going on safari, or even just to your nearest airshow, this makes it a hugely tempting prospect. Of course this long zoom comes at a price - at around £950 / $1070, it's notably more expensive than the older Sigma. However it starts to look like a bargain when you realize how much Canon, Nikon or Sony are asking for their 400mm telezooms.

Headline features

  • 150-600mm focal length (225-900mm equivalent on APS-C)
  • F5-6.3 maximum aperture
  • 'Vibration Correction' optical image stabilization
  • 'UltraSonic Drive' autofocus motor
  • Available in Canon EF, Nikon F and Sony Alpha mounts

The competition

The Tamron's 600mm focal length is the longest in its class, so if it's absolute reach you're after, it has a clear advantage over other lenses currently on the market. The Sigma comes closest, with the camera manufacturers all offering 400mm instead. Canon's 100-400mm is now looking distinctly long-in-the-tooth, while Nikon and Sony have both recently updated their contenders. Click the links for full details on each lens.

All of these lenses offer ultrasonic focus motors, and the Canon, Nikon and Sigma also have optical stabilization. Sony's excellent 70-400mm doesn't, as the company's Alpha mount SLRs use in-body sensor-shift image stabilization instead.

Lens test data (APS-C)

We think the Tamron is just as likely to be used on higher-end APS-C cameras like the Canon EOS 70D, Nikon D7100 and Sony SLT-A77 II as it is on full frame, so in this report we'll be looking at how it performs in lab testing on both formats. It doesn't do too badly on APS-C, but is somewhat weak at the long end, with relatively low sharpness and quite high levels of lateral chromatic aberration.

Sharpness Sharpness is highest at 150mm, and progressively decreases as you zoom in; by 600mm the lens isn't especially sharp at all. In general you'll get the best results on stopping down to F8, light permitting. In context though, the Tamron's performance isn't too different to the other lenses of this type aside from the Sony 70-400mm, which is unusually good at the telephoto end.
Chromatic Aberration Chromatic aberration is distinctly high at 600mm, with strong red-cyan fringing at the edges and corners of the frame. It's not so bad at shorter focal lengths, and is very low indeed at 300mm. Note that while most Nikon SLRs will compensate for this in their JPEG processing, Canon and Sony cameras won't.
Vignetting Vignetting is very low, as usual for a full frame lens used on APS-C.
Distortion Distortion is low, which again is normal for a full frame lens on APS-C. There's a little pincushion distortion at all focal lengths, but it's unlikely ever to be a problem.

While the Tamron may not be at its best at 600mm, none of the other lenses we're looking at reach that long at all. So to make a fair comparison, we have to look at how they match up across their shared focal length range. For example, in these tests the Sigma 150-500mm F5-6.3 DG OS HSM is no sharper at 500mm than the Tamron is at 600mm. Meanwhile Canon's ageing EF 100-400mm f/4.5-5.6L IS USM simply can't keep pace with the Tamron's far more modern optics; it's simply not as sharp when compared like-for-like on the EOS 7D.

Compared to the recently-announced Nikon AF-S Nikkor 80-400mm f/4.5-5.6G ED VR, the Tamron manages to keep pace optically across the shared zoom range - there are some small differences in measured sharpness here and there, and the Tamron has slightly higher CA at 400mm, but overall the lenses are more similar than different. The only lens that comes out noticeably ahead in any way, in fact, is the Sony 70-400mm F4-5.6 G SSM II, which offers spectacular sharpness wide-open at 400mm.

I wanted this lens to take equine event pics. I have tried several times to take Bucking horse pics, roping pics, etc. When moving no matter if on tripod, monopod, or hand held. cannot get clear pics. If it is sunshine they are not bad but indoors in event arenas not good at all. I have tried all settings nothing works. I had wondered about the lens creep due to the fact that most time I am shooting down into the arenas to get the best pics. I have taken wildlife pics and it works great. Landscapes good, just not the moving of horses. Birds in flight not good either, but sitting still good. I want a lens that will take pics at about the 100 to 300 range and be sharp with the center focus of action. Any recommendations on this lens or another would be appreciated.

Dear friends,

I hope the following may be of some value. Mounted to Sony A900; 850 as well as A77 bodies, I initially experienced very, very frustrating problems with sharpness at 400-600mm - especially at long exposures. 2 weeks ago (out of desperation) I bought a Manfrotto MVA513WK Sympla support, and strapped the lens barrel onto the support. The results are truly amazing. Almost every shot - including exposures exceeding 3 minutes - are now pin sharp. I reckon that the real issue is that the barrel (when extended) is simply too long to be stable - so even the slightest vibrations introduce distortions.

I have a pretty hard time believing this in real life, quite honestly. I think the Nikon 80-400 G stomps it in just about every way. I got to do a nice comparison and purchased the Nikon. It's sharper at every common focal length and the AF was much better (at least on my D7100) It was faster with little hunting and much sharper wide open at 400mm.. Note that I do handhold the Nikon most of the time but when comparing these too, I used a Gitzo tripod with a Wimberley Gimbal. I have been shooting long lenses including some pro lenses like the 200-400 F4 and 500mm F4.
Of course, the Nikon costs a lot more, comes with a crappy tripod collar and only has a 400mm reach. Still, I greatly prefer it.

In general, I have not had any luck with Tamron lenses. I am now buying Sigma lenses like the 18-35 and 50mm Art prime instead of Nikon because I think they are better. After testing a couple of Tamrons I have always returned them. Maybe I am consistently unlucky with the samples.

Did you fine tune the Tamron? I have no problems with mine on the D7100, AF is fast and accurate with no hunting. I track Ospreys diving and fishing with it all the time at 600mm and handheld.. Check my flickr page.. https://www.flickr.com/photos/coastalconn/ maybe you had a "bad" copy?

@Conan, I use LR5, basic stuff, adjust shadows/highlights.. WB and set black point. I generally leave sharpening at default. If the image is noisy, I use PS CC to mask the bird and do background noise reduction. I then just do a high pass at .3 and 40%.

@Kris in CT:While doing homework I was drawn to your photos before looking at this review. I also want a lens to use in and around wetlands on my d7000 here on the Mid Atlantic coast. I agree.....the photos on your Flickr account, to me, look pretty sharp at 600. Thought I would wait until Sigma releases their "C" lens and wait for comparisons. Now I hear they have no release date in mind for that model. Now I am considering the Tamron.

The swedish photomagazine FOTO has published an extensive review on their website, with MTF data measured on the lens itself, without the need of a camera being involved in the process. They do it in cooperation with Hasselblad who use an advanced optical bench. Seems to correspond rather well with DP Reviews findings. FOTO is rather pleased with the quality. There are also some actual high resolution pictures. The text is in swedish but Google Translation makes most of it understandable. And the diagrams speak for them selves.

I just bought mine yesterday and took a couple shots of my dogs with the Sony A77 II. The light was flat but the images came out pretty decent. I purposely shot at 600 mm F8 to confirm if I wanted to keep the lens. The images appeared sharp and contrasty enough under normal viewing conditions. Even cropping, the images held up OK. This is not like older lenses where the images always appear a little dull. The modern optics really make a major difference. My primary purpose for this lens is to shoot at 12 FPS and I am willing to sacrifice a little sharpness even though it does not appear that I will have to. If I do find it a little less sharp at 600 mm, that what Photoshop is for.

Hi GEGJr,

I use my 150-600 extensively with A900 and 850 bodies. However - initially I was disappointed - especially at 400-600mm (in spite of mounting it on a very sturdy tripod). When extended 400mm plus, the barrel is simply too long to be stable. Following a few mishaps, especially in windy conditions - I bought a Manfrotto MVA513WK Sympla. Believe me - this is awesome! I do Engineering Forensics - last week I shot 2435 frames for a particular investigation of rows of soil anchors - all at 600mm; f16, at night with LED lighting - with average 5 sec exposure in a wind gusting 8-12 knots. Only 17 of the shots were not pin-sharp - and that I ascribe to errors in my manual focussing.

best regards,
Johannes

Yesterday we had the chance to test this Tammy in a shop in Frankfurt (Germany) both with our Canon and Nikon gear and bought a copy with Nikon mount. AF performance with the Nikon (D300S) was quite good out of the box. With our Canons it was a mixed bag. AF performance of the test copy was overall okay with our 7D, but not with our 5D3.

Checking the test images I noticed that the lens was heavily backfocusing on the long end with the 5D3 and would have needed severe microadjustment. I remembered that Bryan Carnathan reported the same issue in his great review:
http://www.the-digital-picture.com/Reviews/Tamron-150-600mm-f-5-6.3-Di-VC-USD-Lens.aspx

Overall I agree with Brian's findings after this brief test. The Tammy is no match for a good prime supertele on the long end, but delivers surprisingly decent IQ in the 200-500 mm range. One big plus over the Bigma: f = 5.6 already @ 400 mm available. If AF issues can be solved it is definitely a great travel zoom for wildlife shooters.

I have been using mine for about 6 weeks now on a Nikon D7100. Mostly, I have been using it for photographing soccer games but have had the opportunity to shoot some wildlife. I hadn't realized just how poor the sharpness would be at 600mm. I kept thinking I was doing something wrong on my end! Still, on a well-lit day, I have much greater reach than my 70-300 on most areas of the pitch. I am very happy with this lens!

Have you tried with smaller aperture? It might require to stop down more, with the risk of losing AF. Still, if it's sunny day, the AF "could" work even with very small aperture.

0 upvotes
Adrian Gopal

At 600mm a lot of other factors also come into play not only whether you use small apertures. Vibrations, slight movements when pressing the trigger, mirror slap all become more amplified. Shooting with the 70-300 at 300 and the 150-600 at 600 are very different experiences. At 600mm all the above are just a few reasons why images may not be so sharp. I have had the lens for about 2 weeks now, and at the 600mm end, I have to consciously be aware that at 600mm I needed more care to get the same result I would with my 300f4 in terms of sharpness. Mind you my 300f4 is the older non AF-S and has no VR. So I think it's a matter of getting the technique right.

I'm not sure what you are talking about Lassoni, cameras always autofocus at maximum aperture (at least for still photography). It makes no difference to AF whatsoever what aperture you have set, even if you are setting it manually on a lens aperture ring.

Lassoni

I meant that, the tammy might not be sharp enough wide open (not with all bodies atleast? With D800 it might be sharp). Maybe it's better with a D8xxs than with a D7100 (or canon 5dm3)

0 upvotes
SMPhoto

I get that part, my comment was the part about risking losing AF by stopping down to gain sharpness. Stopping a lens down to a smaller aperture for whatever reason has no effect on a camera's ability to autofocus. Only adding a teleconverter that reduced the maximum aperture would do that.

Suhas Sudhakar Kulkarni

I have another perspective, to help understand if the lens performs better on DX or FX - IF WE REQUIRE EXTRA REACH, i.e. 1.5x crop mode.

For example, Nikon D610 has 10MP in 1.5x crop mode. You upsize this image to 24 mp and compare the upsized image against 24mp image from D7100 (both images from Tamron 150-600 with same exposure and same conditions)

If this test shows that the upsized iamge is better than the image from D7100, then only one can conclude that the lens performs better on FX FOR TELEPHOTO applications.

I've had the 150-600mm for about a month and use it on a d610. It is exactly what I needed to capture the big birds along the lower Ct. river. I've yet to get a good eagle shot, but with this lens my hopes are high. I have posted my first pictures here: http://www.crowsandsquirrelsarefree.com/new-lens-test-pictures.html
I am a complete novice with a long lens and have had incredible luck for the first couple of times out. Especially so with birds in flight and all hand held.

i prefer 300mm f4 cos it has wider angele and exactly same details as 400 5.6 offers
i wait for Canon 36-50Mp camera to get full performance for 400mm 5.6
no slow zoom can compete with 400m or 300mm prime lens in shrapness

u may compare tamron 150-600 and canon 400mm 5.6, canon wins easily
and there is dimension and weight that is very important
its joy to use 400mm 5.6 u can follow all birds in flight
try it with 150-600mm zoom
no zooms!

there is also no point for teleconverters cos even 1.4 makes image so much softer that its no way better than it wud be without converter
i know i have tested all
only way to go is prime lense
i dont have 500, 600 and 800mm prime, cos i dont want to spend money for that
i better invest it elswhere
and be happy with 400 5.6

For all birders and wildlife photographers: in Scandinavia, after shooting atlantic puffins, I had a brief talk with a guy using the Tammy with an EOS 7D. Overall he was quite happy with this lens and its IQ, in particular in terms of price-performance ratio. The only drawback is AF performance. He said that he had completely given up to try birds in flight with this lens. I have to add that even with a Canon supertele it is a real challenge to get a good BIF pic of those speedy little puffings (they fly with about 80 km/h), but it is not impossible.

So the AF performance of the Tammy is a limitation at least birders should be aware of. Otherwise this lens is so attractive that I personally still think about getting me a copy for those trips I can't take my 500 mm prime with me/ I want zoom flexibility.

Supposedly Tamron has a firmware update that addresses AF for Canon bodies. It seems to track fine on Nikons...

That's good news as they might be able to improve a Tammy's AF performance step by step with this and future firmware updates. Tamron like Sigma and other 3rd party lens makers have the problem, that they have to re-engineer Canon's and Nikon's AF systems. Otherwise they would have to pay them a lot of money to use their native AF control parameters.

A Sigma 300-600mm with wider aperture would be quite a beast (depending on the aperture of course) and surely located in a different market in terms of size, weight and price, more like Canon's and Nikons 200-400/4. The "Sigmonster" 300-800/5.6 e.g. is a lens that you can't compare with the Tammy 150-600, it costs about 5 times the Tammy's price (in Europe). Past yr I had the occasion to test a Sigma 300-800. This is really a monster lens, heavy like a truck, you always need to carry a good tripod with it. I shoot my EF 500/4.5 quite often handheld, but with the Sigmonster - no chance.

I wouldn't be so sure about the weight and price of 300-600 tho. Aperture will most likely determine it, as the tamron 200-500 f5-6.3 weights only 1.25KG, very much lighter than this tamron 150-600 f5-6.3 . 5.6 on a 800 is WIDE.

Didn't check this but I guess that the old Tamron 200-500 might have much less lenses included than the new 150-600. I understand that the new construction is quite sophisticated. More optical glass means more weight (the new Tammy has a plastic housing).

Re the Sigma "wide aperture" 300-600 we can only say now: it's all rumors, nothing else...

Nice to have but I am not in that type of photography. I like scenic, portrait, table top, hence my lenses are (for Nikon FX): 24~85mm, 24~120mm, 135mm all at f/2.0 max aperture and (for NIkon DX): 18~55mm and 55~300mm. I converted my prime lenses for my Nikon F and used those much more than the 55~300mm. I hardly use the 55~300mm. Where I like super long reach, my Video camera with it's 70X zoom take better picture of the moon than any of my Nikkor lenses. The craters are more detailed than the 55~300mm lens.

I have one of these lenses. They've been in very short supply in Australia but I managed to get one by acting quickly when I heard a shipment was due a few weeks ago.

I've got both D7000 and D610 Nikon cameras. After using it to capture my favorite kookaburras high in a tree (using the 610) and later attempting to use it in an equally useful way in the D7000 I've formed the opinion this lens is best suited to a FX (full frame) sensor camera.

SO far the inability to auto focus from close to distant without help is the only issue I've discovered. There's a switch on the barrel to limit the distance... A sort of workaround for the problem. I haven't had results as good with the D7000 as I got on the FX body. Maybe that will change as I become more familiar with it. So far I'm liking it very much. Something I didn't expect from a Tamron lens.

I have had the Tamron 150-600 for 3 months and taken over 3000 photos with it. I initially had some softness issues but changing to a Canon 70D and using the AF micro-adjustment to adjust for both the wide and long range ends of the lens, essentially eliminated the softness issue.

I know put most of my focus issues down to operator error and are extremely happy with the images I get.

A bit of exploring DxO's results shows it outperforming (slightly) Canon's old 100-400mm L, and being outperformed (slightly) by Nikon's new (and horribly expensive) 80-400mm. Seems like a very good deal to me.

I am a bit puzzled that the sharpness seems to decline so much between 400mm and 600mm on DX but hardly at all on FX. I guess it has to do with the pixel density of the DX camera used (presumably something with a 24MP Sony sensor in it).

FX users have been reporting drops in sharpness from 500 to 600mm. Tony northrup was very clear about this minor issue too.
Let's be honest just use it at 500mm it's a bargain for it's performance there.

DX sensors are more dense and require sharper lenses. That means this will fall slightly short. Still the only real better alternative is a 400mm and up prime lens or an 200-400mm zoom. and those are very very expensive indeed.

This is an extremely complex lens with 20 optical elements and almost 2kg weight. You can imagine that half the weight comes from the expensive optical glasses used in the lens construction. When a company produces and sells for only $1000 a lens of this caliber, we can only applaud. Bravo, Tamron!

I am using now the Sigma 150-500 with my Nikon D7000 mainly for birds photography
Am using it without tripod. The focus is very slow but otherwise it's OK up to 400 mm
I want to upgrade to the new Tamron. Lab results are OK but I would very muck like to hear someone who actually tried both lenses specially before going on a safari.
Is the focus much faster? Are the result on 500-600 OK

Many thanks
Yochi

I think you might be a tad disappointed with this lens if you intend to use it on a small sensor camera. I've got both 610 and 7100 Nikons and I only get excellent results on the 610. From what I'm told by other people who've tried one expecting to get 900mm virtual lens length, its the same story.

You might like to wait and see if Tamron intend to introduce APS-c specific lenses in the near future. BTW, this is not the only full frame lens I've used on a clip size sensor that doesn't produce the same quality image as it does on a full frame one. Just my opinion. Others may have different opinions. You could always hire one and see for yourself if it suits your needs. I still prefer the 120 - 300 Sigma with a 2x extender on it for really crisp results but the cost is a lot more.

Thanks for info douglas69 - My personal experience is from Canon C100 usage so this do not apply to the DSLR world. I will actually rent the 120-300mm 2.8 and a 2x adapter to test. Thanks for reminding me of that lens :)

Yes, likewise I use the 120-300 2.8 and 1.4 and 2x Siggies on DX (D7100, 1 V2). Can't speak for the Tamron but the Siggy kit is good gear. My big primes only come out these days when I really need the light.

I've been told by a store guy (when testing tamron 150-600) that sigmas 50-500 has better auto focus tracking than tamron. It might also be so slightly sharper than 150-500, but it could be worth testing if you can test it at some store.

I tested the tamron on a nikon FF, but I dunno whether the store guy was referring to reports from canon users where there seems to be some complaints on the autofocus of tamron. Didn't get to shoot any birds so cannot say anything for myself.

You'll probably find the Tamron has considerably better engineering in it than the Sigma. Having said that, I'll go on the say my short experience with the Tamron makes me feel it is best suited to a full frame camera. I'm not getting as good results with my D7000 as I get from the D610. You might also find the pixel density of the D7000 is why.

It's all a bit of a trade-off. It will probably perform better at 550mm than 600, and better still at 500. So if you need 600 to fill the FX frame, you might only need 500 to better that reach on DX, at which it might be sharp enough. Swings and roundabouts, and only some careful testing in the field would sort it out to your satisfaction.
The Siggy 120-300 + 2x is only 550, incidentally (but a true f5.6), and sharpest at 500 (backed off a tad) but excellent at that on DX. So might be the Tammy, but slow.
Engineeringly, yes, possibly, although the 120-300 is an upmarket Sigma. Mine needed two trips back to the factory before it performed, but it is now close enough to optically perfect. A Sigma issue is individual variation - I had to buy two 1.4x's to get a sharp one. Tamron has done consistency better in the past.
This lens is in their newfound cheap but good category, like their 70-300 SP VC. I have an excellent copy of that one, which outperforms my Nikkor, but reports vary.

I had the Sigma150-500 on my D7000 and it was very soft at 500mm. Thom Hogan gives it a very good status, but only 200-400.
When I purchased my D7100, it showed up how really soft the lens was at even 400mm.
I now have the Tamron 150-600 and it's truly excellent, even at 600mm (at F9).
The difference between a photo of a Sea Eagle with both lens shows how much sharper the Tamron is.
I'm so glad I sold the Sigma and purchased the Tamron.
Of course it's new technology, so it must be be better.
I'd feel really sorry for anyone who bought the Sigma lens, now that the Tamron is out. A couple of hundred dollars isn't all that much for a lens that is twice as good!

I've used the Tamron 150-600 on a D5000, D7000 and full frame Df. FWIW, my most detailed moon shot came from the D5000, in my experience the greater pixel density of of the D7000 isn't of any great benefit at 600mm (900mm equivalent) where resolution drops off. The Df is my preferred body with this lens because of the low noise characteristics of the sensor at high iso, but the lens is exceptionally fun to use on any of these bodies. VC is very effective and hand held shots at 1/60 sec. at full zoom are generally acceptably sharp but typically shots (daylight) are taken around 1/500, iso 800, f/8 with faster shutter speeds for subjects in motion. A tripod definitely increases keeper rate. Focus speed is good and accurate. Bokeh is generally good, often excellent. I have lenses that are sharper with more contrast, maybe focus faster, but for long reach and very good all around function this lens is truly remarkable and worth a try.

I would like to see a Sigma 300-600mm OS f/4 or f/5.6 (depending on how the size, weight, price balance out).

Obviously, an f/2.8 is not only completely unrealistic without tens of thousands of dollars -- but I think a shorter zoom range (a simple 2x optical design) and f/5.6 optimized for f/5.6 is possible. I wouldn't want an f/4 that was too expensive.

Time for a lens revolution.

1 upvote
GlobalGuyUSA

You cant have a lens revolution in terms of size, you can only gather so many photos at a specific front element. I suppose material science could find some alternative to glass that weighs less, but the plastic used for lower lenses is not the solution and anyway the lenses need to be the same size. Unfortunately, light can not be sucked into the lens like a vacuum picks up dust, so there is no way around this. That is why the focus is on sensor technology, not lens technology. The most you can do with lens technology is improve clarity and reduce scattering. Anyway f stops are in principle a kind of ratio or specific amount of light depending how you think of it, so its not like f/2.8 will mean anything else except that ratio for that much light gathering.

It would be nice to see how the sigma's new 300-600 is going to be priced, probably way higher than I think.. if so, what if some of these companies produced something like sigma's 100-300 f4.. which is said to be sharper than sigma's 120-300 f2.8, and lighter? Anything under 2kg (between 1.3-1.6kg) with a maximum aperture of 4 or 5.6 AND with OS would be a very very good candidate. Heck, even the tamron's 200-500 with some image sharpness boost + VC would be a true killer.

Well now... I just shot 250 frames of a Aussie rules football game using the 150-600 lens exclusively on a 610 Nikon body. F8 at 1/2000 second, ISO 1600 and guess what?
With a modern, full frame camera ISO 1600 is no real noise problem. I slowed the ISO down to 400 in an attempt to get ball smear but with shutters speed of 1/250th there was to much of the scene blurred so I upped it to ISO 800 and found a happy compromise. Using a Monopod and switching off the stabilizer produced almost instant focus. I'm beginning to love this lens. I'd post some shots but I haven't figured out how to include them yet.

Quick calculation suggests that the front element of a 150-600mm f/2.8 lens would be something like 220mm (9 inches) across! That's roughly twice the diameter of the Tamron lens, and thus about 4x the volume and probably 4x the weight.

I keep seeing the sigma 150-500 compared to the Tamron. The Sigma 50-500-OS is the better lens. Sigmas 150-500 has ALWAYS been a stinker. I tested 3 of them they were ALL sub par even compared against my first gen 50-500 non OS let alone the newest 50-500 OS. BUT it does cost more so maybe thats why but still.

Which is really WEIRD isn't it? Why does Sigma -- who is undergoing significant efforts to increase their brand, allow this to stand?

I hope they come out with a simple 2x optical design 300-600/f5.6 that is optically superior to the Tamron and sharp as hell at f/5.6 to replace the 150-500. A 200-600/f5.6 is also acceptable, but honestly, we have so many lenses that go beyond 200mm now that its just not necessary and just adds weight, cost.

Suggestion: We hear mostly that these lenses perform better on FF sensors than crop sensors, but how about a direct comparison? A 24mp DX like the Nikon D7200 versus a 24mp D610. Same shot, same subject, same distance. Then, crop and upsize the D610 shot and see how it matches up.

1 upvote
misolo

I don't think that comparison would make much sense: if you know you're going to crop you should be using a crop sensor for the higher resolution, which will of course do better. You'd want to look at the D610 at 600mm f/8 vs. the D7200 at 400mm f/5.6, with the D610 set at one ISO stop higher. Then you'd be getting otherwise more or less equivalent photos (in field of view, depth of field, shutter speed, total light/shot noise, etc.), and you could have an more fair comparison of optical characteristics (resolution, chromatic aberration, etc.)

3 upvotes
GlobalGuyUSA

What Misolo saided. The D7100 in full mode will have more resolution than a D800 in crop mode.

So for "sunny" pictures (where the highest ISOs are not needed), and at apertures like f/8, there is really no one who is saying that Fullframe is better. You'll get more out of a cropped camera, if that's what you're looking for (indeed, this is THE key strength of APS-C other than weight and size). The 600mm end will be a true 900mm, whereas the D800 will be throwing away pixels do get that digital zoom.

By contrast, Fullframe is better at wide angle (in general) and getting a narrow depth of field and at low-light.

misolo

GlobalGuyUSA: in addition to those issues (depth of field, low light, etc.), I think the original question was regarding the optical quality of the lens. Using the full image circle is less demanding of the lens' resolution and less impacted by lateral chromatic aberration (because, for the same total number of pixels, each pixel is larger). However, a crop sensor, while more demanding of resolution, uses the "sweet spot" in the center of the lens where resolution is highest. Which works better overall depends on the lens. Lenses with very soft corners work best in aps-c. Lenses that have good corners (and/or not very high center resolution) work best in full frame.

Your "sweet spot" argument doesn't really hold up well...I see many, many lens tests where DX tests out much worse than full frame on lenses designed primarily for full frame cameras. The data for this lens is no exception. Look at 600mm f6.3 and even f8...the DX is far worse. My 24-70 f2.8 lens is the same. Sharp wide open at pretty much every focal length on my D700, noticeably softer unless stopped down on D7000 or D7100. AF fine tuned on both bodies.

GlobalGuyUSA

Hi Misolo,

That's a good point, but I think you have it correct (edges), and the OP had it backwards. Of course, it all depends how important edges are to you. The middle and even far middle is generally pretty good throughout Fullframe lenses these days, even if edges tend to get rotten. And yet, when you're doing tele work, often the center is the important part, and often you want a smaller f/stop (f/16) when you can get it. So FF helps with diffraction for the reasons you mentioned, and you still get the whole sweet spot within Fullframe as well. I guess it pretty much comes down to whether one needs sharp edges for ones work.

But if you look at the APS-C vs. Fullframe tests (on this page), you can see what Westerner is pointing out -- some Fullframe lenses just seem to work better on Fullframe cameras (and I have no idea why). In this case, there is a significant level of difference between FF and APS-C sharpness, in FF's favor. Again, I'm not sure why this is.

Just like the Tamron the Sigma 150-500 OS performs much better on a full frame sensor.

I'm not sure that one can compare Fullframe and Cropped bodies directly like that in DxO measurements -- they use different standards, and it varies by body as well.

I think you can more directly compare with other lenses on the same body and to a lesser degree in the same format. But to cross bodies and formats is pushing it.

It is always easier in my opinion to work with the native focal length than to crop but you ask an interesting question of the Sony 400 cropped to 600 v the Tamron @ 600.

One thing is for sure is the Sony is an outstanding lens @ 400mm. It is it sharper than the Tamron but it is slightly faster as the T stop is f6.3 for the Sony whereas it is f7 for the Tamron.

I don't think you would lose the SSM because the Tamron is not a screw drive lens on the Sony. It uses the same electronic focusing mechanism as the Canikon variants.

It may or may not be as good as SSM but it certainly won't be a noisy screw drive.

If I already owned the Sony this review would not having me upgrading. I would know I would be getting a lens less sharp @400mm for the sake of the range 400-600.

As it is I don't own the Sony and great lens though it is, I can't justify paying that much when the Tamron sells for approx £500 less than the Sony. or will do when they get around to releasing it ion Sony mount!

I'm soon to have my sigma 400 5.6, which is 500-600g lighter, and probably sharper than the tammy @ 600 (with a TC). Only downside is sigma won't have OS, but I can live with that since I wouldn't like to handhold the tamron personally (tried at store twice on different occasions, didn't like it).

These things are subjective, like how some ppl perceive its weight. How soft it is however is something that is evident in both the reviews of the lens and now even here in dpreview.

Is it better than my current lenses? It certainly provides more reach than any of my current lens (400 5.6 yet to arrive). BUT! At 600, it's just as soft / performs equally soft as my 70-300 does, which is not very nice thing for something that imo weights a little bit too much. Canon folks can just get their canon 400 5.6 over this..

Stop down ever so slightly at 600 and it sharpens right up. Also note that a 600mm on Canon, one still has full AF, unlike using the 400/5.6L with TCs, where one has no AF on many bodies and slow AF on 1-series and the 5D III. A sharp lens is meaningless if the subject is not in focus.

And how does your 400mm lens look at 300mm? 200mm? Can you swap your 70-300 in as fast as the Tamron can be zoomed out?

I think you may be compensating for something; I hope it's just stupidity.

Hi - I took the Nikon version out in April on my D3s with a friend shooting a Canon 500 F4 IS on a 7D. Looking at the results - birds I would say the Prime and £5k+ of lens has it- 'feathers'. Walking like a hunchback, the Canon has it. Been able to shoot into the air longer - less hand weight, the Tamron has it. The noise from the 7D makes me feel a little better as it delivered nothing like the D3s on ISO. There's so many 'if's' about this lens because of price. I traded my old 80-400 in for a Tamron (I liked my old 80-400) so expected at least as good. Tamron F6.3 - well need some depth of field and F7.1 up looks ok, but I'm not selling pictures to an art gallery. Some samples here: http://www.digital.ac/tamron150-600/
The Kite is edited - bad day, bad light. The auto focus on a D3s - easy on a Kite, easy at Kart racing. Not a spectacular piece of glass, but the person pushing the buttons contributes. Dislikes - the zoom creep. Likes - picture quality, zoom lock and 5 year warranty.

Which is what I was saying above, if you infer that the Sigma at 300/2.8 is almost as good as 300/2.8 primes, then the Sigma with their 2x will be almost as good as a Canikon 300/2.8 with a first-party 2x as well.

Just note that you're losing the ability to zoom out with the 120-300/2.8 + 2x while spending over three times as much and carrying around a significantly larger and heavier lens.

Though I have no doubt that the Sigma would be worth the effort :).

I think the reason they don't bother with that is, if the near end is lousy, they might as well have made a prime 600 and gotten absolute top quality at the far end. Or they could make a very short zoom length like 400-600 rather than 150-600.

Or it's just that it's really embarrassing if you shoot something ten feet away and it looks awful. Makes your lens look bad even if the 600mm shots are amazing.

Or much higher quality elements and coatings that don't eat at the transmission so much- OR have a wider physical aperture to get the measured T-stop close to what the lens is being marketed as.

Though if you're shooting astro, one would think that you've gotten a sky-tracking rig set up so that exposure times matter very little, and thus a particular lens' T-stop also matters very little.

TT Martin, apart from VERY FEW EXCEPCIONAL optics like the Zeizz 55mm Otus, Sigma Art, Canon 200-400 etc almost none of the others do as well on higher pixel density sensors!
There are other reasons for it for sure, but since canon reached 20+Megas MANY years ago, and way ahead of all the others, they were also the first to experience the lack of lenses able to REALLY DELIVER ALL THOSE megapixels!!! It comes not as a chock that in last years they produced some of their truly record breaking definition lenses instead of bringuind the oh so awaited 42-56megapixel sensor that ALMOST NONE of the lenses would be able to use!!! (not to mention the photographer's tecnique! ;)
Besides, since usually 600mm lenses are used from a rather long distance, air conditions and proper tripod and or techinc will be WAY more importante then the pure optical definition! ... (continuation below)

It is fully compatible with the 1,4 EX TC with remarkably little IQ deterioration, which makes it (IMVHO) the lens of choice in the under $ 1.500 tele-zoom bracket. As such, I can't help wondering how the Tammy would hold up in comparison.

So where is the test of the AF performance like tracking etc.
There is more to a lens test than lines per millimetre.
Take a browse around the forums to see the more important part of the review DXO completely omit.
Its not pretty.
When oh when will DXO start testing properly and include AF performance which is far more important than an extra 5lines per mm of sharpness.
Try tracking a bird with this lens..good luck.

DxO is not a camera review site. They make software for correcting issues with lenses and camera sensors. They collect data to help allow that. They generously share some of the data with the public.

If you'd like to see a culprit, it's dpreview.

the review says:
"What these laboratory optical tests can never tell you, though, is now well the lens's autofocus and image stabilization systems work for real-world shooting of these kinds of subjects. You can get a feel for this, though, by reading... "

Tracking performance depends strongly on the camera body that is used (and the type of subject, experience of the user etc.).

I think it tracks very well. http://www.dpreview.com/forums/thread/3676468 These are some tracking tests I did when I first got it. The first series is normal daylight conditions with a D7100, the second 2 are on a rainy foggy day with a D600

As I said above:

The Kite is edited - bad day, bad light, a little high (Cropped). The auto focus on a D3s - easy on a Kite, easy at Kart racing. Just dropped the D3s down from 51 points or use with 3d tracking, stick D3s on manual with auto ISO and there you go. Quite tricky on smaller birds though because they are in and out of the viewfinder so quickly. Ok for me but opinions will vary - I am not a bird shooter in general - just wanted to see what it did.

@RichRMA and others worried about the tele-side: check here for another comparison of this lens at 150mm and 500mm wide-open:

http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=929&Camera=453&Sample=0&FLI=0&API=0&LensComp=929&CameraComp=453&SampleComp=0&FLIComp=4&APIComp=0

You'll see that if anything, their sample of the lens was sharper at 500mm...

This illustrates the big problem with lens testing sites: sample variation is very real, and basing nice numbers on just one copy is very much flawed! I've read somewhere that Roger Cicela from LensRentals acquired a new testing unit or so - here's hoping that he'll use it to systematically test at least ten copies of every type of lens he has and share the results with us. Because as it stands, lens review sites are pretty much useless to assess what one can expect from a lens sharpness-wise.

Roger has already tested many copies of most lenses with their previous equipment; this shows that copy variation is a fact, but usually the differences are so small that you would hardly notice in practice (check the older articles on the website). However, some copies can be outside the 'normal' performance range and in that case exchanging them would be the best option; problem is, a normal user can't compare to other copies so it is difficult to know if there is something wrong with the lens, or if there is another problem (e.g. AF adjustment woes, other camera problems, user error etc.).

Well, I'm a scientist, and if people present me with a number my instinct is to ask "how reproducible is that number?". It happens often that lens A is tested sharper than lens B on one website, while the inverse is true on another website. So either one of the people doing the testing did it wrong (which I choose not to believe in case of the better known review sites), or lens variation does play a role. Roger Cicala indeed has done some comparitive testing in the past on sample variation, but usually he also just gives a single number "because that's what people want": http://www.lensrentals.com/blog/2012/09/why-arent-the-damn-numbers-the-same (check the first graph btw and tell me the variation on the average isn't interesting to know about...) DxO Marks is particularly good (read: poor) at presenting their results as absolute values...

@Greg VdB:
"So either one of the people doing the testing did it wrong (which I choose not to believe in case of the better known review sites), or lens variation does play a role. "

Probably they are just both using different testing / evaluation methods, not necessarily 'wrong'. Depending on test conditions and test methods the results could differ strongly. Lens testing is not 'objective' at all, and the result will depend strongly on the exact testing procedure (focus distance, lighting, focusing, camera body used for testing, etc. etc.). Which isn't a problem as long as you understand how they get the data and what you can use it for. Sometimes unfortunately - like with DXO - it isn't clear at all what the testing results represent, so DXO rankings are of little value to me.

I'm a scientist too, but I prefer actual images to the average lens test because most tests as performed by review websites tell me very little about real life performance.

UNLESS... your name is Roger Cicala and you are actually more interested in the quality of what you writte instead of how easy and or fast you can writte it!!! :)
If Dpreview has a shop they sure could test several exemples of a certain lens IF they wanted!!! :/

I agree with Greg VdB as I've been testing and comparing Canon lenses for years and yes, significant variation is real even with L glass. Just ask Klaus at Photozone who routinely tests several samples of a lens and posts the best results. He also comments on centering defects which are quite common especially with image stabilized lenses. The other issue is method and technique for testing a 600mm lens especially on APS C. Some sites comment on the issue of getting valid results just due to the lens to target distance.

They have million $ machines generating the (easy) spherical curves on the lenses used in those cheap teles. They should be as uniform in production as can be. Unless mechanical tolerances are very sloppy (to facilitate rapid production) I can't see there being much difference between copies.

@RichRMA:
it isn't easy at all to make a 'perfect' lens, if it was there would be many factories churning out high quality, low cost lenses ... Seems to me you have no idea of the difficulties of lens design and production.

Greg, I agree. There are huge variations at times in lens models and DSLR models. I had three different Canon 7Ds before I found one that did not have focus issues. I've had Canon 5Ds, 5DIIs, 40Ds and 60Ds, but the Canon 7D was the only one that had severe front and back focus issues with different L lenses. Later found out this was a common issue for the 7D that Canon had never made public or recalled.
I also tried two Canon 70-300 L lenses before getting a sharp copy. Even on DPR if you look at the Canon 7D test shot you'll see that the camera is back focusing. The playing card in the back of the image is tack sharp, but the Bailey's bottle image with the tree and pasture with fence are less sharp than other comparable DSLRs.
If the lenses and DSLRs are not calibrated before a test the results are not really usable.
