[QUOTE="pforsell, post: 613011, member: 7240"] It seems like a camera glitch to me. All the settings are reasonable and there's plenty of buffer time too. The interval length is the full cycle time, containing shutter release + exposure time + shutter close + possible long exposure NR time + card write time + maybe 1 second extra time just to be sure, and the remaining time is gap between shots. Here you have: * 0.1 sec shutter open * 5 sec exposure * 0.1 sec shutter close * no long exp NR = 0 sec * 2 sec write time * 1 sec extra * ... and only 1 shot per interval This is only 8.2 sec in total, way below the 60 sec interval you have set. Camera glitch is the only explanation with these settings. :( There are a couple of settings that can cause problems in some cameras, for example self-timer and mirror up modes, but I believe these are not compatible with D7100 interval shooting. Please double check that the lens is firmly in manual focus mode, because the camera tries to re-focus before every shot in AF mode. No focus, no shot. [/QUOTE]
