Autofocus performance on the D7100 is on par with professional-level DSLRs and includes a 51-point focus area with 15 cross-type sensors for detecting both vertical and horizontal variations to achieve fast, precise focus. The central cross-type sensor works down to f/8, which is an advantage when using compatible tele-converters. The D7100 features the option of a 1.3x crop which allows you to get closer to your subject, as well as providing more image size options and faster processing of your images, including a faster 7fps burst rate.

Full HD 1080p video is supported on the D7100 and offers professional-level control including continuous autofocus, manual exposure control, a built-in stereo microphone and an external microphone and headphone jack. Recording at 60i, 50i, 30, 25 and 24 frames per second is possible and an HDMI output allows for direct screening on an HDTV. At 720p HD you can record at 60p frames per second for smooth slow-motion sequencing.

A 3.2" 1229k-dot TFT-color LCD provides 100% coverage for accurate playback and live view composition and the pentaprism optical viewfinder features an OLED display element for clear reading of the camera's settings without removing your eye from the finder. Dual SD card slots offer large memory capacity and the ability to designate which images go to each card. A built-in flash with commander function supports Advanced Wireless Lighting and a hot-shoe/accessory mount is available for speedlights. The D7100 is lightweight and durable with magnesium alloy top and rear covers and weather sealing to prevent dust and moisture damage. 

The D7100 is compatible with all NIKKOR F mount lenses, both DX and FX format, and can provide wireless connectivity with the optional WU-1a Wireless Mobile Adapter. With the WU-1a and Nikon's free Wireless Mobile Utility app installed on your smartphone or tablet, you can instantly share images and use your phone or tablet as a Live View monitor.
