[QUOTE="SGC2.0, post: 353962, member: 31369"] Hey guys, first post here (I wasn't sure if there was a semi-mandatory/recommended 'Introduction' post so I'll just start with a quick one and then move on to my question.) I'm a hobbyist photographer, mostly I use my cameras for stop-motion animation. A couple years ago I bought a D3100 and eventually outgrew it, so I just upgraded to the D7100. So far I'm very happy with the quality of the images and the feature set of the camera! I generally only use my camera in a studio setting where I can really think about and test exposures without pressure, but my day job is as a graphic designer in a smallish firm where I am (as of late) frequently called upon to be the 'in house photographer' for clients. Okay, so with that primer I'll get to the meat: I cannot get two of my AF-S lenses to auto focus with my D7100. They auto focus perfectly with my D3100, but when I mount them to the D7100, if I don't already have the lens AND the body set to 'M' then when the camera is turned on the top LCD display just shows the little battery icon and it flashes, but the icon is of a full battery, not an 'empty battery' icon. If at any point I switch the body OR the lens into 'A/M' or 'A' then the camera immediately locks up and doesn't function at all. It's not that it won't autofocus, it just won't work. But setting everything back to manual focus and everything works (except auto focus obviously!) In my animation studio this is not a problem, I wouldn't dream of using autofocus, in fact I don't even use AF lenses, I use all old manual glass), but when called upon to do quick photo shoots at work, auto focus is kind of important to me! The two lenses that refuse to allow auto-focus operation are the kit lens from my D3100, the AF-S 18-55mm f/3.5-5.6G ED II lens, and the other lens that won't auto focus is the 18-70mm f/3.5-4.5G ED IF AF-S DX. Neither of these lenses function in auto-focus mode, but work just find in all manual mode. Now strangely enough, my 50mm f/1.8D AF Nikkor auto-focuses just fine with this camera. i cannot for the life of my figure out why that lens will focus just fine, but the other two will not. Everything I have read suggests that this camera should work just fine with those first two lenses. So if anyone has any ideas, I'm happy to hear them! If I haven't described the issue clearly enough, or you need more info, please let me know. Thanks! [/QUOTE]
