    • 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 does not 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

    The sensor of the D7100 uses Nikon's DX format, resulting in a crop factor of 1.5x. Additionally the software enables an additional crop of 1.3x (resulting in approximately 1.95x compared to 35mm). Selecting this additional crop mode allows faster focusing in video mode and also enables interlaced video recording modes. This additional crop feature gives D7100 an advantage in using tele angle lens for shooting wildlife or things at a distance. The 51-area AF system sensors will be covering a bigger proportion of the extra 1.3 crop factor image area, which is important for capturing high-speed moving subjects during shooting.
