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.

Boasting a 36-megapixel FX format sensor, the Nikon D800 is currently the highest-resolution “35mm size” digital SLR camera in the world.

And it handles bright, saturated reds, pinks and purples very well, without blowing out any detail.

For example, in our shots taken a gym that was dimly lit by sodium lamps, chroma noise is clearly visible from around ISO 2500 when the images are viewed at 100% on the computer screen.
