On What is equivalence and why should I care? article (1489 comments in total)

I APPRECIATE you including the f/stop equivalencies.

As photographers, we don't want light, just for the sake of light -- we want it for the sake of a certain "feel" and "effect." Thus, every bit of more information is always helpful.

It doesn't hurt having too much information, it does hurt having none.

Thanks!

Make sure you only use it on a sunny day.

You would think that in this day and age of technology they could do a 150-600 @ f2.8

Wheres my Brownie 127

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.

Huh? Check out the brick building near the bottom right corner, and a yellow structure near it. There is no question about which one is sharper - of course it is Panasonic. There is not difference in the center, but FZ1000 clearly wins in the corners, at least at wide end.

You're right -- about that lower right hand corner. But as for the rest of the 3/4ths of the image, the Sony is sharper, including the center.

Which makes me wonder about that lower-right hand corner.

Its a bit weird compared to the rest of the image, isn't it.

RonHendriks: You can also compare it to a Nikon 1 series camera.

The Nikon 1 is directly comparable (a step-down mirrorless to 1", just as these are step-up bridge cameras from even smaller yet sensors). The field is converging. Nikon has a way to go with 4K -- but they are not focused on that. They are focused on AF. The 4K market doesn't even exist. No one has the TVs, fewer yet can work with the files, and its just not pressing in Photography, except for those with an Audio Video emphasis (which isn't Photography, properly). There are an unlimited number of Audio & Video forums on the web. You might want to check those, if Photography isn't of interest to you? They might have better recommendations and comparisons. In this case, if you're looking for 4K you probably want to compare to Audio-Video equipment and specialised Camcorders -- not Cameras.

I would like to see FUJI make a rival to this one.

Sony often forgets how users "feel," but Fuji is doing pretty good there.

When you say the Sony is heavy-handed in its processing -- is it able to be reduced through the software (to a degree whereby its not really heavy handed)?

RichRMA: 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.

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.

TTMartin: Very informative.

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

Guess it is time to give it a try on my 6D.

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.

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.

Daniel Clune: 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.

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.

Richard Murdey: I don't feel concept of "early adopter" even holds true with dSLRs. Every new model is always better than the old one. Your only choice, given how the price drops over time, is when to buy it, and the only gamble/risk is whether you are going to be getting a camera that will be replaced with a new model in four years (D700), two years (D800), or just one (D600).

@InTheMist

Production errors vs. Design errors. Against the # of sales, the D800 & D4 did not have significant problems (far less than most consumer electronics), easily resolved with an exchange. The D600 was the only one that had a significant DESIGN flaw, where it did not work as designed. Design flaws are different than production errors, which Canon and Samsung and Sony and Fuji and everyone else suffer from too. 100% of D600s included a shutter with a flawed design, whereas only 1 out of a 100 or more other models have production errors based on tolerances of micrometers (test your gear after you buy it) - very small.

Similarly, the SB900 did not have an overheating problem, it functioned exactly as designed (as intended it shuts down to cool to avoid burning out). What Nikon found is that users didn't like the way that feature functioned, users want it to just slow down as it heats up. So Nikon made a new one that took into consideration when flashes are under stress.

D600 was a fluke. Their legal team gave them crappy advice to cover it up with an incremental upgrade, but it was too obvious, because Nikon never worked on a yearly cycle at FX.

The threat of lawsuit set them straight -- which is what lawsuits are intended to do! But I would not count on this happening again in FX.

If anything, this is an extremely blessed time to buy FX, because how messed up the pricing is, thanks to that ridiculous fluke. You can buy a PRO Nikon FX for anywhere between $1000-$3500 dollars: D700(used), D600, D610, Df, D800, D3, D800E, D3S(used), D810, in that pricing order.

ALL EXCELLENT CAMERAS (and the D600 even has a 100% guarantee behind thanks to Nikon owning up finally to the problem). No one has a right to complain in this environment.

Its a wonderful time for FX users.

peevee1: "Sometimes we need a gentle polish, a tidy-up and a fix for the things that didn’t work so well the first time. And in the D810, that is exactly what we are getting"

How do you know that? Being an untested Nikon camera, it might have problem with focusing, or with oil, or they managed to invent some new problem. :-)

Besides, being intermediate "almost-non-upgrade" means than the next upgrade will be as big as D700 to D800E. You simply get more value being an early adopter after a significant change than early adopter of basically the same old thing - much more life left in your purchase.

I thought that they have a Hands-On preview already?

If so, that's probably how they know that. Although the author certainly leaves the doubt...

Jonathan F/2: Nice ad (masquerading as an article) to help bolster Amazon pre-orders.

That's true Jane -- it wasn't there when my page loaded the first time (its definitely there now)!

That being said, that add is just a "Support this Site" ad -- which is fine and seen on every single Lens & Camera review page. Amazon may make a higher percentage, but it also means they are less desperate than your favorite Camera/Lens review sites. So I don't see it as a conflict of interest -- its just exactly the same interest.

So either we dismiss every site that has a "Support this Site" link, or we give this article a chance to stand on the merits. On the merits, its a REASONABLE article which supports incrementalism against those who think that no new body should come out until a revolutionary feature is added.

I happen to agree with this article. If I happen to not be ready to buy a D800 in 2012, and I am ready in 2014, then I'm more than happy that Nikon has a D800 Mark II -- aka, a D810 ready for me. I'm happy I don't need to wait 2 years for a D900's features.

GlobalGuyUSA: Does anyone know if its possible to have "FOCUS PEAKING" in LiveView with a Nikon or Canon DSLR? I noticed they added Zebra stripes to the D810 -- but what about Focus Peaking in LIVE VIEW mode? Isn't this possible?

Its a shame Nikon named the new horizon level "Split Screen" because what I am thinking is that in a Df 2 camera, when in LIVE VIEW, the user should be able to have Focus Peaking + a simulated "split screen" (Katz Eye style) for manual focus (by magnifying a circle in the center and applying highlights when its focus).

Just a thought!

Thanks. Its just a thought. I think for "Live View" this would be exceptionally helpful, especially with a center circle magnification that can be touch-screen moved around and toggled off and on.

Care to elaborate?

"Zebra stripes" are well known to Olympus users. Google the term. Nikon added it to the D810.

It was a nice opinion piece, and a worthy Response to the "Thom" critics who thinks that incremental improvements are not worthwhile because they contribute to "pollution" in the market.

In fact, Nikon is increasing the rate of releases (which affects resale values) but actually increases options (and makes used products more affordable). Whether or not users can continue to purchase at this rate is questionable (and so at least part of that pollution concept is quite valid).

That being said, there was no advertisement here, no link to Amazon pre-orders. The person who mentioned Amazon was you, but you could have as easily mentioned Adorama or B&H. The article is a positive commentary on incrementalism in the marketplace, as opposed to the radical transformations we've seen in the past.

K3 with 18-135: $1400

It's not that it's priced like an APS-C camera, it's that it's priced like a TOP END APS-C camera. I mean those lenses are all a LITTLE less of a zoom and their apertures favor wide to tele (which IMHO is an advantage) but this cam's got a lot of high end competition. Not like the RX10 fits in your pocket.

Darngood -- almost all of them reach 200mm equivalent. And it IS directly comparable because even if a lens is technically an f/2.8 on a 1" sensor doesnt mean it behaves like an f/2.8 on fullframe in terms of image results. Technical is the same as total perceivable equivalency. Its 2.7x crop factor mean images will appear as if shot by an f/7.6, even if the technical light ratio is the same.

Meanwhile, the APSC lense perceived equivalencies are f/6.5, f/8.5, or f/9.5, when compared against the f/7.6 of the Sony, even if technically f/4-6.3. All pretty much in the same range & the APSC sensor is much, much larger and can have better ISOs in the same sensor generation AND you can change lenses, allowing actual f/2.8 equivalent lenses (such as a technical f/1.8, or even better, f/1.4), smoking this Sony.

So yes, its 100% comparable with the price. Sony should be under $900, otherwise its way overpriced by 40%. Not a bargain, considering even lower range DSLRs will do a better.
