I intend to use it for birding, sports and events photography as well as a back-up to my 5D3. The photos of the birds you took look reasonably sharp. It looks like the softness issues I've read elsewhere may be due to user error.
U may be right about user error..but i had so many shots and none(seldom or never had such incident) are TACK sharp and Iam not sure if it could be focusing issue. I just did another test for both 1D4 and 7D2 on 85mm using MF and heavy cropped. This time I feel the 7D2 looks ok with better details due to crop sensor,I guess.
1D4

7D2

Would appreciate if more users could share your photos and your feedbacks..
In our birding community already have quite a number of people owning it and I believe more sports photographers have it out there.
Anyone out there can advise me if its focusing issue?
I called up Canon and the CSO said can't be not sharp...must be either camera or lens need calibrate. What's your take?
