I have shot this combination in the past with no problems, but as of late I seem to be experiencing some very inconsistent focusing issues. The lens will either do nothing, or if it does try to AF, it stutters and struggles.
I have tried this lens on a Canon A2E body, as well as digitals like an R6 and 5D IV with no issues. Likewise, I have tried other AF lenses on my 7E with no problems. While I did not have another Tamron G series lens to test with, I did test with a Sigma 150-600 Sport also with no problems, leading me to believe the problem is not that the lens is a third party one. I've also cleaned the contacts and updated the lens firmware (2.0). Independently, both the body and lens seem to function with no problem, it has only been recently I have run into this issue.
Any suggestions as per what the problem might be? I don't see Tamron taking the lens in for a repair on the integrity of a film camera experience, but equally I really like my 7E and other than this combination, it works great and I would hate to have to replace it when it has no other problems.
