Some objective evidence
Parameters:
RAW
ALO, PIC, NR, Sharpness all disabled manually/set to zero in camera AND in Canon DPP (Very important to do this)
DPP conversions at setting 8/10
Combined in photoshop and saved at setting 11/12
White Balance set to Kelvin - 2800K in both cameras
Manual Exposure under same lighting condition.
Slight difference in shadow intensity is due to different camera sizes affecting angle of lens to the target.
Slight difference in exposure must be due to the inherent design of the cameras as exposure parameters were identical
Slight difference in WB anc contrast must be due to tonal response curve and WB Shift as Neutral Picture Style was used during conversion and capture, and WB was maintained at 2800K on both
Lens used 85mm f/1.2L II at f/8

It is possible that my 5D2 is defective, but as it is cleaner than my 1D3 and 40D, so they must be very defective too. And so must my 1D2N and 400D as they are much inferior.

My take is that 6400 on the 5D2 is like 3200 on the 5D.

I have shot both extensively, and my general feeling is that the 5D2 is worth one to two stops of higher ISO performance.

5D2 is a stop or more better than 5D1.

I had the 5D I for 4 years; now two 5DIIs.
Clearly better than one stop. 1 1/2 stops or 2 stops? Somewhere in that range. That fine a difference is difficult to tell.

I have to disagree - I believe if you downrez a 5d2 iso 6400 image it is more than a stop better than a 5d iso3200 image.
I'm really interested to know why I get different results, do you guys still have the 5D to do a comparison?
