I don't know. That is why I'm asking you. You seem to know. I don't hold tv shows in such high esteem, but that's just me.

Kim Kardashian has her own show. Jerry Springer, silly Housewives of <insert flavor-of-the-month-city>...

Well, I don't know about you, but I do find photography shows at PBS, or even National Geographic photography shows quite interesting, regardless of what camera brands are used.

Kim Kardashian? I had no idea that she had a photography show on PBS. Are you sure that you aren't referring to the "Star" magazine?

Thanks for posting that. It reminded me of the 5D3 problems with banding. Just saved me 2600. :)

DPReview completed their 7d2 review. This time, they have a separate section for this comparison (exposure latitude). They are implying that, banding is correlated to DR and 7d2 has better DR. They even did a real world DR test with older D7000. Not sure why they have to compare with older model. Difference between 7d2 and 70D is also negligible.

Hahah... still worlds behind the Nikon in detail capture/retention in the blacks.

Is the D7000 a Sony sensor? (Anyone happen to know off hand? I'm too lazy to look it up.)

Not sure why DPR selected D7000 instead of D7100. I think, there won't be much difference anyway. It is good review with lot of information.

Yes, the D7000 used an Exmor.

Thanks jwcdds for doing these comparisons! I too am finding I'm very happy with the high ISO performance of my 7D2. I recently had to a belly dance gig with fast primes nearly in the dark -- ISO 10000 did not look terrible, recovered a lot of beautiful dance artistry that we saw with dark-adapted eyes.

You're welcome. Amongst my Canon camera bodies... so far, 7d2 remains king for shadow pushing with very minimal banding.

Unfortunately, I don't know how the 5DS/R handles and have no plans to pick one up any time soon. (I can't imagine 50mp files blowing up my hard-drives :lol: :)

This interesting. I may have to revisit and retest this. When I was comparing my 7D2 to my 5D3 I found the 5D3 much cleaner in the non shadow areas.

I took multiple shots on an overcast day with both my 7D2 and 5D3. The exposures were both the same but at 100% the 5D3 was much cleaner. I did post this about 6 months ago and called it a muddy look. I know my 7D was a light hungry camera and just assumed the 7D2 is as well due to the pixel count on that sensor.

Not that I'complaining about the 7D2. I love it and shadow noise has always been close to the bottom of the list of concerns for me. Interesting to see that the 7D2 shadow recovery is much better with your tests. It looks great and I'm looking forward to trying it at a concert where I usually use my FF.

When I did some MFA with for my 100-400 II and 1.4 II I had a few underexposed shots I kept and ignored that I just opened to try it. The shadows looked pretty good as I pushed the exposure.

Here is my 7D2 example. The areas indicated with the red arrows. There is what I call a black peppery transition between the tire and the green bus body. I could not see this with the 5D3. The 5D2 was much cleaner in the green body area as well. I'll see if I can find the link and or a 5D3 image.

It appears the 7D2 is better at pushing shadows but the 5D3 is still more forgiving when it comes to exposure?

Here is a 4 stop push, anything more than that on the 7D2, and it gets pretty ugly, at least with my copy. 4 stops is all I would ever need though, so that makes me happy. I need to do the same test with the 5D3, but I am quite sure based on past experience, the results are going to be worse. There is a little bit of color banding, but nothing like prior models with the argyle patterns.

Banding is related to electronics noise on the lower bits of the digitized data, which is why it generally disappears at higher ISO. There the A/D converter is being asked to capture a smaller range of values with the same number of bits and so the lower brightness values have more bits representing them. This tends to suppress pattern noise in the readout. If we had truly linear 16-bit A/D converters instead of the 14-bit chips, both pattern noise and dynamic range would be a little better for all cameras. Hopefully soon they will become more affordable.

I don't care much about shadows at low ISO, fortunately, because I use my 5D3 and 7D2 mainly at higher ISO - where the Raw output is at least as good as the Sony/Nikon system. And yes, the 5D3 will be a little more forgiving of underexposures - the larger pixels have about twice the full well capacity so at a similar data number (A/D output) the S/N will be higher and the effect of shot noise on the lower values will be less noticeable.

I did this test at ISO 100, and assume that it would reflect what perhaps a landscape shooter might have to do. The 5D3, pulling up 4 stops, most likely won't be quite this clean. It has been a while though where I have had to pull up a 5D3 image 4 or more stops, and quite frankly don't remember what it looked like.

Since I have both cameras I guess I can do the same. I assume you would ETTR both to match the DR on each one as closely as possible?

I ran the same settings and same lens on both bodies, using the same exact exposure settings, just varied the FL to try to get the same FOV for a better comparison.

The 7D2 and 5D3, after pulling up 4 stops, are very, very close to each other. The 5D3 did better than I thought it would. I know I have seen patterns from pulled exposures before, but at least in this test, that didn't happen.

Here is the 5D and 7D overall pics before pulling 4 stops out as best I could using DPP (exposure slider and histogram sliders).

My sister,friends and cousins have Sony/Nikons and hand down they kill the Canon I have and my buddies 6D when it comes to pushing files and even editing them in general .


The advantage Canon has is the lens selection, it's enough not to switch over yet. Also I like the skin tones from Canon OOC, you can get them as nice on the Sony sensors but they require a bit more tweaking.
