This wired controller, very useful and even necessary to make the macro picture is not suitable for the Nikon D7100, catches of the latter, including the USB (with USB wired control) are different, and probably specific for d Other Nikon equipment. On the D7100, there is an HDMI (HDMI can connect an audio / video source DRM - such as a Blu-ray player, computer or a game console - to a compatible device - such as an HDTV or video projector) which is a kind of jack of all trades, perfect for multiple uses, but not for connecting a wired control. As the D7100 is the latest Nikon cameras, remote control ML-L3 without wire was considered by Nikon engineers as an alternative command "wire" .It can, but we must then trust the device managing this long exposure (night picture or candlelight) .Under three caches on the D7100, we discover a GPS jack, a headphone jack, an HDMI, a USB plug and finally a microphone jack . It is complete, but for my kind of nostagiques déclanchements as on older boxes silver glass plate, the change is brutal! I would add that I use the "ML-L3 small and convenient, but for different use
