First post to this board. HELP!!!! I have the EF 70-200 mm f/2/8L IS III USM lens, purchased 7/2019. When I say it is minimally used, probably used not more that 8-10 times. It has not been mishandled whatsoever! Something has happened and it is not auto focusing. I put in the repair for an estimate and it was right around $400.00. Before I send it in, I thought I might get some suggestions as to what might have occurred to cause this. And is there anything I might check on the lens or in camera. Nothing appears to be wrong with the lens settings. Suggestions please!!
Okay, if the lens switches are good, then I assume that means both AF/MF and focus limiter switch are good.
What about other lenses? Can you auto focus with other lenses, too? Is the camera set for BBF?
