You know, rereading this post, one might come to the conclusion that there is, or is not an issue. But I have dozens of photos where the background is in focus and the subject is not. Each time I go for a close up of virtually any kind, I get AF lock on the subject and the background is what is actually in focus, I go out about three times a week, so I have many dozens... Well that I have deleted. I have just had to start using manual focus... Which for me is like taking a step 20 years back. I have a X-E2, Nikon D800, and Leica X-2 none do this as did none of their predecessors. It happens with my 35mm F2, my 60mm... And I am sure the others, but I don't off hand specifically remember examples, so I will not include them.
Where is the best place to contact Fuji. Do they have a, 'send a message to Fuji" somewhere, or maybe it would be better to attempt to send the camera in for repair? JD
