Despite having to send it back for repair, I am glad I made the pre-order purchase. I knew what I was potentially getting into by doing that. Canon was quick to resolve the problem and get it back to me at their expense.
There a lot of reasons why images could be soft and there is no doubt that many of them have some kind of factory assembly and/or calibration issue. Did you check the AFMA setting to make sure the camera is matched to the lens? After that if the images are soft, then there could be some problem and a good idea to send it in.
My 7D2 works all as good now as my 5d3 and have actually been using my 5d3 as a backup since I'm well into sports season now.
Definitely yes, I can say I'm a master at AFMA. Spent so much time trying to calibrate an 85mm to my old 70D that I know everything about it by heart (turned out that the 85mm had an inconsistent AF that would front/back focus randomly).
Spent also many hours trying to calibrate all my 6 lenses on the 7d2. Every lens needed some adjustment to be focusing properly, but it would only work well in a controlled environment (well lit room, with fluorescent light, distinctive focusing target) and once I took it to the real world the focus would miss quite often. But even on the micro adjustment sessions the image was still soft compared to my previous cameras.
I've read somewhere that only about 1 in every 20 lenses should need some AFMA, at first I thought I was extremely unlucky that all my lenses needed some correction on my 7d2. But with the 5d3 it was just plug and play, my lens are fine with no adjustments just like it should be.
Well I can tell you that the one in twenty rule is hog wash. The reality is that most people would not notice if afma was off 5 clicks. Just stop down the lens to make it sharper, right?
All of my Canon lenses required afma on all of my bodies except 1 lens. My sigma 35 f1.4. Out of the box afma was perfect at 0 on my 5d3. I have 10 canon lenses and bodies. All required afma. So the requirement for afma is generally subjective unless you have a way of measuring it using a tool like a spyder lenscal.
Anyway, regardless, you have experience in that process and went through that so I would then say you should have canon check it out. I got to the point where I could afma my 600mm lens and the next day it would be off again by like 5 clicks. There were other issues too such as unable to lock on subjects and losing lock once acquired. Other things were unable to focus on the foreground object in zone AF mode, inconsistent front and back focusing, unable to determine what it focused on. Ai servo was mainly useless. One shot gave better results but until I could settle on an afma setting that was questionable.
I would get about 10% success rate and I felt that was more of a random luck thing as the ai servo would jump around jittery as hell.
Now, it locks on, stays locked and in The rare instance I get an out of focus image it's usually my bad tracking. I never shoot out of ai servo unless I have low light. No AF jumping around on even still subjects.
It is fixable and it should work as expected. If it's not then something needs repaired or recalibrated.
