Sigma OS 50-500 vs 150-500 vs 80-400 vs 120-400

Yes, it seems Sigma offer a ridiculous selection of lenses in very similar focal lengths.

I'm interested in Sigma OS telezooms going to at least 400mm, preferably 500mm. I intend for them to be used on the D800, except mostly in DX-crop mode.

I only have experience of the Bigma 50-500mm (non-OS version) and thought it delivered decent IQ (tho' my camera at the time was a 4mp D2H). It didn't really go to 500mm...more like 450mm or 470mm. But the IQ and focussing was not bad at all, better than I expected anyway.

But it's massive and heavy. What are the other 3 options like?

Sigma OS 150-500mm
vs
Sigma OS 80-400mm
vs
Sigma OS 120-400mm

I don't need the wider-angle focal lengths, I need the reach. Most important factor is:

good IQ even wide-open at the tele-end, with reliable focussing.

Any other suggestions of an AF zoom lens going to at least 400mm with stabiliser function? Price has to be similar to these lenses (so unfortunately no Nikkor 200-400mm).

Thanks.

I've been reading a lot about these lenses today and the consensus seems to be to go for the 150-500 but a few voices said a 300/4 with a TC gives better IQ..

The 50-500 OS seems to be well reviewed... I can't afford one, but if I could I would get it.

I am currently using 100-300/4 + 1.4x TC when I need extra reach. IQ is quite good throughout the range for distance focusing (shots within about 8m at 300mm f/4 degrade slightly, but stopping down for these shots helps immensely (and when you are shooting small things that close you generally want to stop down for DOF anyway). I find this to give IQ at 300mm and beyond around 8m distance to be pretty much on par with 300/4 AF (which I also had, but sold), with the added bonus of being able to zoom to the wide end when you are too close. Focus without the TC is lightning fast, and with the TC it is decently fast (about the same as my 18-105).

It does not have OS (a distinct disadvantage), and is about the same size / weight as the 50-500, but I don't think you are going to get much better in a smaller package unless you go to a 70-300mm zoom...

Hope this helped a bit.

Good wide open at the tele end? Not going to happen at these price points, I'm afraid. Several of these lenses are great wide open in their mid-range, but none are prime-quality wide open at the long end.

I own the 150-500 OS, and love it. It's great up to about 350mm even wide open. But I have to stop it down to F/9 or so at 500mm to get good results. Even then, it's good mostly at longer distances, and at very close distances (not middle distances).

Sigma apparently figured out that people were reviewing their lenses at test chart distances, and appears to have "fixed" the issue with the 50-500 OS, which tests well at test chart distances, from reviews I have seen.

If you've got the money, get the 50-500 OS. The OS is the best of the bunch (about 3 stops vs 2 for the 150-500 OS), and they kept the IQ good while extending the range to a 10x zoom. 50mm at the wide end is infinitely more useful than 150mm, IMO. They even improved the mid-distance IQ at 500mm as well. You thus (IMO) get good value for your 60% increase in price vs the 150-500 OS.

I use my 150-500 OS primarily as as an airshow lens. Most of the airshows I go to are usually over tarmac/concrete on a sunny day. This causes the limiting factor for IQ to be the air (thermal distortion). The sun means the F/9 aperture isn't a huge big deal, meaning I get shots with it that aren't that much worse than a 500mm prime, while being able to handhold-shoot it all day long (not easy to do with a Nikon 500mm!)

IMO, the 150-500 OS's F/6.3 at 500mm is mostly for high ISO situations. Occasionally I really can use 500mm in darker situations, and the ISO climbs up to extreme levels. At high ISO on my D7000, lowering the ISO one stop makes a big difference in IQ, and more than offsets the IQ loss from the wide open aperture. For me, above ISO 200, I'll shoot wide open. Under that, I'll stop it down to F/9. The nice thing about this is that F/6.3 is only about 1.3 stops worse than a 500mm F/4 prime, so the prime at ISO 2000+ (on a D7000) won't give you that much better than the Sigma wide open, due to high-ISO degradation.

For the price, any of these Sigmas are a good deal. Just don't expect prime-quality images from these lenses, unless you stop down. The big advantage of the primes is the ability to shoot wide open at F/4 (or F/2.8 for the 400's) with exceptional IQ, which is very useful (with the tradeoff of price, weight and bulk).

Here are some pictures at 500mm from my 150-500 (I got a good copy btw):

The Nikon 80-400 has better IQ than the Bigma, but lacks AFS which makes it way too slow for birds and aircraft in flight. Fine for static subjects though.

I have had the 80-400vr, 50-500 and my wife is currently using the 50-500 OS which I bought after testing the 150-500 as well. I would suggest you seriously consider the Nikkor 300 f/4 with converters or the 70-200vr2 with TC20EIII instead.

I like the Nikon 80-400 VR a lot but I wouldn't choose it over the Sigma 50-500 OS unless I needed the slightly smaller size of the Nikkor. I've owned and used both extensively.

The big Sigma surpasses the Nikon in stabilisation, AF efficacy (the HSM won't hunt as long and far as the screw-driven lens when acquiring or re-acquiring a subject), and close range focus ability. Don't underestimate the last attribute - its an important one and the reason I now no longer have an AF-S 300/f4. The Sigma replaced both Nikon lenses for me.

Don't shoot any of the super tele-zooms wide open unless necessary. They all show a noticeable improvement stopped down 2/3-1 stop.

Simply buy a Nikon 300 f/4 AFS (+TC1.4EII) if you want a real exotic, that's all....

I have used them all. I owned the 80-400mm nikkor, the 50-500mm non OS and the 150-500mm OS, and now I own the 50-500mm OS.

The 50-500mm OS is awesome, the sharpest of all you are comparing, non par.

The only one that comes close is the 120-400mm OS sigma. I do not own this but I used it and compared it.

I recently sold my 300/4 with 1.4 tc and got the Sigma 150-500. WIth the built in stabilization I can hand hold and get a much sharper photo than I did with the Nikon using a beanbag on the car window. Very satisfied.
