Says who?
I've seen a lot of user error, but precious little evidence of "bugs"...
Kieth, despite the fact that your camera works perfectly (or at least you think it does) there are many of us with 7d2 that are not working perfectly. Not everyone with these problems can blame user error. I have a 1d4, 5d2, 5d3 for comparison and one of the problematic 7d2. i sent it in to canon, canon confirmed it had AF problems, fixed it and shipped it back. The difference is dramatic. Images are consistently in sharp focus now.
There's a difference between a defective camera unit and a bug or recall-level manufacturing flaw.
Time will tell, but when one person experiences a problem it may be due to a defective unit, when many people experience the problem...
CR is not the only place on the web where people are reporting AF problems with the 7D2. It is a widespread discussion and happening in many circles of photography. Argue semantics if it makes you feel better or more superior, but it does not deflate the fact that there are issues with this camera that go beyond an isolated incident where one person is making a stink.
Neuro, how is YOUR canon 7D2 performing?
When the 7D came out in 2009, there were many reports of AF problems. Threads on DPR and POTN running to dozens of pages describing those problems. YouTube video demos. A widespread discussion that happened in many circles of photography. A couple of people here on CR forums still haven't gotten over it. Where is the Service Notice from Canon for the 7D AF recall?
MY 7D performed quite well. The 7DII bodies I've tried out (three different ones now) have performed just fine, too.
I thought the 7D AF was ok as well coming up from a 9 point AF system. however once I worked with the 5D3, 1DX and now the 7D2, the 7D AF system was so bad that I never used it again. So in hind sight yes it has problems, possibly not design flaws, just old tech that is obsolete and something I dont have time or the desire to deal with now that I have a plethora of new tools at hand. One of the big issues with crop sensors (and particularly the higher MP versions) is that they magnify the imperfections in everything..by almost double(1.6x). Even a perfectly working version will still not perform exactly as well as a 5d3 and certainly not a 1dx. I'll qualify that in saying that the 7D2 has a magnification benefit in that small targets are larger than in a full frame model and "perhaps" easier to acquire AF in some circumstances. The precision is more of the problem (crop sensor) though than accuracy (better on full frame).
Largely to have the magnification factor available, the lack of precision is just something we have to deal with until the next quantum leap in AF technology, perhaps the ability to focus after the image is recorded.
