[QUOTE="OSOK, post: 265284, member: 21258"] I have a question for others out there concerning this lens.I used to shoot the 70-300 exclusively and was waiting for the new version of the 80-400 to come out.I saved diligently and when it was released I bought it.I have heard nothing but good about this lens and I am getting some very good shots with it from time to time. However, it seems like I struggle with getting it to focus with the AF system. I have tried multiple different settings and combinations to see if maybe my sensors are just struggling to choose a focus point.I have even shot on AF-C with a single point and still have this challenge.I find the lens seems to search and jump around alot when I am on a subject, especially one up close, which really seems counter-intuitive to me.When out a ways it doesnt jump as much but I still find many of my photos out of focus.I probably get 70% of my images out of focus and very rarely do I get the one I wanted in focus.I am using a tripod with a ball head, a monopod with a ball head, or a bag to shoot from in all cases (I am absolutely positive it is not a camera movement issue - I do get some with this issue as well but that's on me).
