The announcement of the D7000 came as a surprise for many people following Nikon. A successor for the D90 had been widely expected, but no one was really expecting the successor’s upgrades to be quite so large. The camera ended becoming its own class, in between the mid-range D90 and the professional D300s, although in many areas the camera matches up or even exceeds the D300s’ specifications – even though the D300s is supposed to be Nikon’s flagship DX-format digital SLR.
With 16 megapixels, the camera’s newly developed CMOS sensor had the highest resolution in Nikon’s DX-format DSLR lineup when it was released (although it has since lost that title), easily beating the D300s’ 12.3 megapixels. The camera features a magnesium alloy body, which was previously only found on Nikon’s flagship cameras. Combined with a thick rubber coating for the hand grip, the camera gains serious durability and comfort over its plastic and polycarbonate competitors.
The autofocus system also got a big upgrade. The new 39 point AF array easily trumps the D90′s 11 point array. Nine of the D7000 ‘s points are cross-type points, which are more accurate and powerful than the normal type. The AF array works with a new 2016 pixel RGB metering sensor which allows subject tracking based on white balance and color. Nikon’s Scene Recognition System is also available, which senses the surrounding lighting and ambiance and automatically adjusts the camera’s aperture and white balance.
Movie recording capabilities have been significantly increased, with full HD 1080p video added at 24 frames per second. For lower resolutions, video can be shot at up to 30 frames per second. A microphone jack has also been added to allow for external audio recording although a built in mic is also available. The D7000 can maintain its focus on the during movie shooting even if it or the camera moves, thanks to its AF-F (Auto Focus Full time) mode. This is also available for the newly added live mode that allows for users to use the rear LCD rather than the viewfinder. Movie editing functionality has been added, of which much was taken from Nikon’s top-end cameras.
In continuous shooting mode, the camera can take up to 6 pictures per second, over the D90′s 4.5. An extra SD card slot has been added, both of which can support Ultra-High Speed cards. ISO ranges have been extended from 200-3200 to 100-6400, which can be boosted up to 25600, which allows for photography in increasingly dim situations. A built in sensor cleaning system has also been added. The rear LCD is relatively large at 3 inches, and has quite a high pixel density with a 921,000 display.
The camera includes a focus motor, which makes it compatible with AF, AF-D, AF-S, and AF-I lenses from Nikon, allowing support for lenses twenty years or older. A new lithium-ion battery has been added. The viewfinder has 100% frame coverage, unlike the D90 that had 96%. Diopter adjustment for the viewfinder has been extended to a wider range.
