[QUOTE="fishwrapper, post: 140086, member: 13846"] Can you tell me what the prong/tab projecting from the body immediately alongside the lens mount is? It would be at about the 8 o'clock position as you face the lens mount. I cannot find any info in the camera manual and so far nothing back from Nikon. I have several older lenses, Nikon E Series, and a few Tamron adaptall lenses which all work fine on the D5100 in fully manual mode. Except that the rotating tab on the back side of the aperture ring contacts this protruding tab on the body as the lens is stopped down. I cannot quite reach the smallest apertures on these manual lenses because of this issue. There is a ramped/angled edge on this springloaded/retractable tab, as though something should slide onto it, pushing it back into the body, but these old lenses have square, sharp edges contacting the tab. Bumping into it is starting to mark the edge of the tab. All the literature I have read says that these lenses should mount and function manually....no mention of any mechanical issues. What is this tab supposed to do? The two kit lenses I have, AFS 18-55 VR and AFS 55-200, of course have no aperture rings and don't contact the tab in any way.:confused: [/QUOTE]
