[QUOTE="guillermo_arp, post: 665134, member: 40887"] Me again, so I sent my camera to service, they told me this 1. My autofocus sensor was somehow damaged, they replaced it. I sent the camera along with a 50mm 1.4 AF-D. Now I have this weird problem: - On Short distances, it seems to autofocus just fine, but with a weird looking bokeh at 1.4 (First picture - Left is closest - Subject is a roll of film at 1.5 feet -- RED is weird bokeh, blue circle is where I set my focus.) (ISO 100, 50mm at 1.4 /160). If this is not normal, then it has to be a problem with the lens. - Beyond 3-4 feet the front focus problem seems to be about 23" - Beyond 4 feet everything is out of focus no matter what I do.
