Display, live view and filming
The display on the Nikon D7100 is slightly larger than that of the D7000, with a size of 3.2 inches and 1,228,800 dots or subpixels. The actual resolution is 640x480, or 307,200 pixels. It has extra white subpixels in addition to the standard RGB subpixels. This 'White Magic' technology comes from Sony which used it in its RX100 compact camera. It reportedly makes the brightness of the display twice as high, and the contrast of 1000:1 is equal to that of the D7000. It's not possible to adjust the aperture in the live-view mode, the same as with the D7000. An extra spot white balance has been added, which speeds up setting the white balance in live view. The menu also has a new look compared to the D7000.
With the film mode you can record in 24p, 25p, and 30p Full HD. 60i and 50i is supported by the 1.3x crop mode. Video is recorded in AVC H.264/MPEG-4 and can be transmitted uncompressed via HDMI, like you can do with the D600. The D7100 has a stereo microphone next to the flash hot shoe, something the D7000 doesn't have.
