7d2 IQ thoughts.

Update: At 102400 I was at 1/1600th.
I just noticed when looking through the pictures again, the light changed during shooting... Oh man... I have the same shutter Speed at 1600ISO 7D and 4000ISO 5DIII. So I'll redo it again in a more controlled situation.

I'm sorry, guys... I'll tell you about the new results with samples

Ok, did it again. Same conditions as before, only it was controlled light and I changed the WB in post by an amount of -526K. Then I did 100% crops, which I will load up. Results are:
12800ISO on the 7D only marginally worse than 25600ISO on the 5DIII, so a 1,3 stop difference maybe
6400ISO on the 7D = something between 16000-20000ISO on the 5DIII, so a 1,5 stop difference
3200ISO on the 7D = something between 8000-10000ISO on the 5DIII, so a 1,5 stop difference
1600ISO on the 7D = something between 3200-4000ISO on the 5DIII, so a 1,2 stop difference.
Samples come in the next post.

So 25600-5DIII and 12800-7D

 

[tayassu]

16000 and 20000 on 5DIII and 6400 on 7D

 

[tayassu]

8000 and 10000 on 5DIII and 3200 on 7D

 

[tayassu]

And last but not least: 3200 and 4000 on 5DIII plus 1600 on 7D

That makes a 1,2-1,5 stop difference and that is great, considering age and sensor differences. I'm totally happy with the HighISO performance of my 7D.

Thanks for sharing. Try this test again in low light(evening time), results might be diff.

No, you understood me wrong, the first and second test were in daylight, the third in low-light. I know the the results get different in different light conditions, so I did it in low-light. The shutter speed was always around 1/100th of the ISO number, so I had 1/50th with ISO5000

Try the high iso series on a test subject with some dynamic range in it, your shadows will be horrible.

I agree that 7D is good for a APS-C camera in 2009. Now hopefully 7D mark ii do better than its competitors in 2014.

I know it is not perfect, although I don't find the shadows to be too bad, I just wanted to help its lousy high ISO reputation a bit. Btw, for the shadows I have the correction tool (I think it's called brush in english)
