how I do the test
i. ISO100 & F13
ii. max flash sync speed (5dm2 - 1/200 and 7d - 1/250)
iii. I try to shoot very close magnification (but can't get 100% same ....)
- 5dm2 ~3:1
- 7d 2:1
iv. same lighting (full flash) - as share here
v. all pictures stacked with 3 picture which focus on eye, nose and mouth of the dragonfly
v. AWB
vi. no noise reduction
vii. no sharpening
1. after resize to 1200 @ longer size, we can;t tell much different
Canon 5dm2 - 1200
7D - 1200
2. and if you wish to have a look at full size
Canon 5dm2 - full size

3. a 100% crop
Canon 5dm2
or larger size http://farm5.static.flickr.com/4044/4496967212_babd6190bb_o.jpg
Canon 7d
or larger size

personal view,
i. after calibration, IQ have improve and noise have reduce
ii. overall Canon 7d doing ok and not sure can it be fine tune any further or not
iii. Canon 7d noise still look bad @100% crop even at ISO100
iv. AWB, how could same brand camera have such different at same environment and using same lighting (flash)
I will do another test on landscape soon....
