I was wondering if others have experienced these issues and know of a fix.<ul> <li data-xf-list-type="ul">Manual lenses (AI, AI-S, AI-converted) are the main issue.  The photos seem consistently overexposed and / or blurry. For some reason, the calculated shutter speeds for a given aperture seem lower than they should be. I usually shoot in Auto ISO mode and have tried tinkering with the Max ISO and shutter speed settings to no avail. Ultimately, I'm having to shoot in M mode with these lenses for acceptable photos, but would love to hear of a workaround to get good shots in A mode.</li> <li data-xf-list-type="ul">AF-S kit zooms: These give me better shots in A mode, but occasionally I get overexposed / blurry shots and have to switch to S with a shutter speed of 1/125s or faster to get proper shots.</li> <li data-xf-list-type="ul">modified TC-16a: This is a special case where I'm mounting manual lenses on a modified TC-16a that the camera thinks is a 70-210 F4 AF. Here, performance in A mode is terrible, but its not fair to blame the camera, and I'm having to shoot in S mode with 1/125s or faster shutter speeds to get decent exposures. (@salukfan111 - have you experienced this and perhaps know of a fix?)</li> <li data-xf-list-type="ul">Alternatively, is there a way to confirm if my D7100 body has an inherent problem with A mode? Because its still within the 90-day warranty, so I could still send it in for a fix if needed.</li> </ul>Thanks for reading!</blockquote>
