And the D7100 one-ups its Nikon stablemates with an RGBW rear LCD which offers more efficient operation and gives the option for greater brightness than an RGB panel, making the screen much more usable in direct sunlight.

The Nikon D7100 lets you dial in shutter speeds of up to 30 seconds and has a Bulb mode as well for exposure times of practically any length, which is very good news if you are seriously interested in night photography.

The higher-resolution sensor necessarily has extremely small pixels, which never bodes well for image quality.

It's also built incredibly well and the video mode, while not perfect, is better than any other HD-DSLR we've seen, thanks to its excellent quality, full manual control and 24p frame rate.
