I don't trust their exif, and we are no longer looking at the IR sources. The EXIF data has been edited, so that the lens says the Sigma 50, but at 70mm and the filename is a name that cannot be set in the camera. ;)

Now we have our own samples to work with. And we have DPP that can work with the raws. Finally, we can now do our sharpness tests. This particular thread is purely about ISO and not sharpness/details, as Jim pointed out.

DPP 4.1 recognized the lens as the EF-s 50/2.5 macro and offered to download the lens profile for it. I agree that I do not trust the EXIF either.

LOL well as usual we end up discussing the tests and criticizing results we don't like.

I'm good with the test, thank you very much Jim. We knew the crop sensors would be behind the FF but interesting to see how much.

The 7D2 and the 70D are in the same ball park for noise but the two cameras serve different well defined niches. Purchase choices based on noise would be my last criteria.

Again thank you Jim for your time, resources and effort. Critics I look forward to your test.

I don't care what color they should or shouldn't be, the histogram on the raw is only about 1/3 stop below 0..

dude, I care! 1/3 stop below a middle needle reading... If the wall was gray and I bet it isn't! Expose properly and you'd get a lot less noise!

You are right you would get less noise. But since all are exposed the same you still have a valid comparison.

So far I'm not that impressed with the 7DM2. The week before I sold my 5dM3 and picked up a 1DX so I've spent the last week playing with it. Yesterday, I picked up the 7DM2 for my backup camera (to replace my 7D). I've been shooting a lot switching back and forth between the bodies and its definitely nowhere near as good as the 1DX on the autofocus side. I'd say it's about where the 5D Mark III is on AF performance. I'll keep tweaking it's settings though. I thought I could match up the settings I've been using on the 1DX which seems to be absolutely amazing, but so far the 7dM2 doesn't lock-on as well. I have hopes though that it's just a matter of finding the right settings for it.


EOS-7D Mark II | EOS-50D | 1DX | 100F2.8L IS | 17-40F4L Sigma 50F1.4 | Canon 11-24F4| 24-70F2.8L | 40F2.8 | 85F1.8 | 70-200F2.8L IS II | 100-400F4.5L |300F4L IS | 580EXII | 550EX

OK, the 7DII is noisier than the 5DIII, expected. What bothers me is that this "brand new" sensor is hardly better than the "old" 70D. Nor am I impressed with the amount of detail captured, the 5DIII examples are far better on this count and it leads me to wonder how strong the AA filter is on the 7DII/70D (obviously both have "different" sensors ;) )

I'll be getting into the sharpness part pretty soon. My 7D was so sharp I had to carry bandaids in my camera bag.

Yes, you're right :lol:
I agree also.
Jim made the test, the results was counter analyzed by TeamSpeed with all explanations needed, + every one can download the raw taken by Jim and do their own comparison ...
the test are valid > it's apples with apples !
Good job Jim and TeamSpeed ! thanks a lot for your time.

So my take away from this is:

5d3 has better high ISO proformance then both 70d and 7d2 (I don't think anyone expecting anything but that)

70d and 7d2 have nearly identical ISO proformance.....MAYBE a tiny advantage to the 7d2 (probably nothing that would be noticed in real life shooting)

That about right?

Important thing here is how much better the "brand new" (I quote Chuck on that) sensor is than the "old" 70D sensor. Oh wait....
