Includes 51-point autofocus, EXPEED3 image processing
Nikon has introduced a new addition to its prosumer line of DSLRs, the last camera to be upgraded following the introduction of the D3200 and D5200. The D7100, spiritual successor to the D7000, upgrades the 16.2-megapixel sensor to a new 24.1-megapixel DC-format CMOS sensor, and copies the D5200 in using the EXPEED 3 image processor.
The autofocus has been pushed to use 51-points, 15 of which are cross-type, through a new Multi-CAM 3500DX AF module. The AF system and exposure works with a Nikon's 3D Color Matrix Metering II 2,016-pixel RGB sensor, which also includes a scene recognition system for automatic adjustment to various parameters prior to shooting. The D7100 is capable of shooting at six frames per second at full resolution, seven when using the 1.3x crop mode with a reduced resolution, the release time lag is now a twentieth of a second, and the ISO range goes from 100 to 6400, expandable to Hi-2 at 25,600.
Video can be recorded at 1080p at 30fps, or at 60i and 50i in 1.3x Crop Mode, while sound can be recorded through its stereo internal microphone or an external microphone, with an additional headphone terminal allowing for live audio monitoring. Special effects, such as selective color or "Color Sketch" can be applied to videos being recorded in real time.
The viewfinder now uses a new OLED data display, which also provides 100-percent frame coverage for improved shot composition, accompanying the 1,229k dot 3.2-inch LCD display. A Wireless Mobile Adapter will allow the camera to communicate with a mobile device from up to 49 feet away, allowing for remote shooting and remote collection of images from its dual SD card slots.
The Nikon D7100 will go on sale in March for around $1600 with an 17-105mm lens, or $1200 for the body alone.
