The Nikon D7100 [1] is an F-mount DSLR camera with a 24.1 megapixel DX format CMOS image sensor announced by Nikon in February 2013.[2] It is the successor to the D7000.

Features

  • 24.1 effective megapixel CMOS, Nikon DX format image sensor, without an optical low-pass filter.
  • Nikon EXPEED 3 image-processing engine.
  • Advanced Multi-CAM 3500DX autofocus sensor module with 51 focus points.
  • 3D Color Matrix Metering II 2,016-pixel RGB sensor.
  • HD video mode with autofocus. Up to 1080p at 24p, 25p and 50i (50i true interlaced: based on 50 sensor readouts per second), 30p and 60i (60i true interlaced), 720p at 50p or 60p frames per second (fps). H.264/MPEG-4 AVC Expeed video processor. HDMI out with support of uncompressed video (clean HDMI)
  • ISO sensitivity 100 to 6400 (up to 25600 with boost).
  • 3.2-inch, TFT LCD monitor with 1,228,800-dot resolution.
  • Center cross-type focus point supports autofocusing with lenses with a maximum aperture of f/8.
  • DX sized sensor with 1.5x crop factor.
  • Viewfinder with approx. 100% frame coverage and 0.94x magnification ratio.
  • GPS interface for direct geotagging supported by Nikon GP-1

Video Performance

  • When using the D7100 as a video capture mode, the camera will display audio meter overlays over the left edge of the LCD.
  • The D7100 doesn't allow the lens aperture to be adjusted during video capture.
  • The slowest shutter speed in video capture mode appears to be 1/25th of a second.

Advantages and disadvantages

Although the D7100 has 24.1MP, while the D7000 has only 16.2MP, there are no significant improvement for the newer ones. DxOMark say is "just a smidge better in all regards". The D7100 also removed the Optical Low Pass Filter (OLPF), but compared with Nikon D5200 which has same 24.1MP sensor and still has OLPF, the difference is insignificant. One advantage is D7100 can select on 1.3x crop factor focus area instead of 1.5x crop factor of a whole area which makes faster focusing, but cannot do in video mode.[3]
