Nikon has announced its first DX-format DSLR in 2013 - the D7100. Following on from the popular D7000, this long rumoured model arrives two years down the line and features a number of developments and improvements to separate it apart from its predecessor.

 

At the heart of the D7100 lies an all-new 24.1MP DX-format CMOS sensor. This could easily be mistaken for being the same CMOS sensor as used within the Gold Award Winning Nikon D5200, however at the official launch, Nikon confirmed the sensor is entirely new and is not the same as used within the D7100's DX-format cousin.

Interestingly, Nikon has opted against the idea of fitting the D7100 with an optical low-pass filter, much like they've done previously with the D800E. By foregoing the optical low pass filter (OLPF), Nikon say the D7100 can make better use of its megapixels for impressive high resolution, with the benefits outweighing the negatives. 

The DX-format CMOS sensor is designed to work in unison with Nikon's EXPEED 3 image processor - a combination that contributes to an ISO range of 100-6400, which is expandable to an ISO equivalent of 25,600 in the Hi2 setting.

A new 1.3x crop function also opens many new possibilities for photographers. It enables the camera to shoot at a maximum continuous speed of 7fps, which works out at 1fps faster than the D7000. When the crop mode isn't used, the D7100 can shoot full resolution images at 6fps, but when it is it also allows full HD movies to be recorded at 50i. One feature the D7100 doesn't offer for moviemakers is audio monitoring, however, there is an inbuilt mic port for attaching an external microphone and there's 30p,25p and 24p frame rates to choose from. When the 1.3x crop function is used for shooting stills, the resolution drops from 24.1MP to 15.1MP.

Another big improvement is the D7100's AF system. It uses Nikon's MultiCam 3500DX autofocus module, which offers 51 autofocus points, 15 of which are the cross-type in the central area of the frame. Nikon claim the AF detection is now faster, plus autofocus operation is possible under a combined aperture value of f/8, meaning more combinations of lenses and teleconverters can be used.

For metering the D7100 uses the tried and tested 2016-pixel metering sensor as seen before on other Nikon DSLRs such as the full-frame D600. The optical viewfinder offers 100% coverage and just below this lies a new 3.2inch screen, which boasts an impressive 1229k-dot resolution. Another new development at the rear of the camera is the inclusion of a new 'i' function button. Used as a means of gaining access to the most frequently used functions, it's located at the bottom left of the body, below the zoom out playback button.

Constructed so that it's rugged and lightweight, the D7100 features magnesium alloy top and rear covers to give it a durable feel in the hand. Weighing 675g, the camera is sealed to combat moisture and dust creeping in to the internals and Nikon say the shutter has been rigorously tested for 150,000 shutter cycles under demanding conditions.

At the side of the body there's a dual SD card slot. This allows users to save JPEGS files to one card and RAW files to the other. Alternatively, there's the option to record still images and movie clips to separate memory cards if you'd prefer.

Although there's no built-in Wi-fi capability, the D7100 is compatible with Nikon's WU-1a mobile adapter - a small accessory that enables images to be transmitted to Apple or Android smart devices such as smart phones or tablets. This additional extra costs £49.

Battery wise, the D7100 uses the same battery as the D7000, however, a new battery grip has been produced for camera - the MB-D15. This costs £279 and is made from magnesium alloy to match the same build quality of the camera.

The new Nikon MB-D15 battery grip (£279) has been specially designed for the D7100. 

At the same time as launching the D7100, Nikon also released the WR-1 wireless remote transceiver. The WR-1 features a dot matrix display and a score of advanced features that enable the user to take control of most of the shooting operations - from simple remote shutter release to complex, multi-camera set-ups as well as possibility to check and change camera settings when mounted on the Nikon D7100. Various shooting scenarios can be pre-programmed, including simultaneous shooting, interval timer photography as well as customised shutter release delay. The WR-1 is expected to cost £649.

The new WR-1 wireless remote transceiver features a range of operation up to 120 meters. 

 Available from the end of March, the D7100 will be made available (body only) from £1099. Alternatively, the D7100 will be made available as part of a kit with the 18-105mm AF-S DX NIKKOR f/3.5-5.6 G ED VR lens for £1299.
