Review - Canon 5dm2 vs 7d MACRO

I got an unit of Canon 7d for testing last 2 weeks ago but the results were unbelievable so I send back to Canon service center for checking and yesterday they call for collect after do some "minor" calibration .....and today I went out for quick test (my testing only based on on personal standard/interest and may not a good comparative among 2 Canon bodies)

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

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....

Other - Why I Always request Larger Picture before comment

I love to view pictures .. I can simply open flickr, pbase , google picture and spend hours without drink , eat and concentrate to view pictures ... but I seldom comments other's picture... as web size (low resolution) 800-1000 pic @long side will definitely not should what we see in actual resolution 100% crop , and to judge the picture sharpness, details...

even a non sharp picture after re-size with little sharpen the picture will still look good in sharpness and details, and we have no way to tell is it a picture with details or is the len sharp or not ...

let have a look at picture 1 & 2 which is web size
1. worthwhile picture - Web Size


2. un-wanted picture web size



with 100% worthwhile picture and unwanted picture
3. 100% crop picture #1


4. 100% crop picture #2


all picture from process with very close
1. raw --> jpeg (no sharpen)
2. increase contrast
3. 100% crop on head
4. redo and resize and save

as the web size picture (800-1000) is very low resolution so it is no way to tell how is the len sharpness and picture details ... so you know why I ask for larger picture :D

with small resolution picture, actually I can make very sharp and look many details pictures by just little extra PP
