The D7100 uses the same EN-EL15 battery
and MH-25 recharger
as the D7000, but has a new battery grip, the MB-D15 Multi Battery Power Pack. It records images on SD/SDHC/SDXC cards via not one but two slots housed in the large right-hand compartment. This allows you to use two cards in tandem, with the ability to overflow images onto the second card, backup images from the first to the second, or save RAW to slot 1 and JPEG to slot 2. It also obviously greatly expands the overall memory capacity, useful if you shoot a lot of images in a short space of time.
The Nikon D7100 follows conventional DSLR design in having a shooting mode dial on the top of the camera, now with useful lock button in the centre, which allows you to select either one of the advanced modes like Manual, Aperture- or Shutter-priority, or 19 different scene modes. The new Effects shooting mode provides provide 7 different filters that can be applied to both still images and movies. The Night Vision effect is particularly worth of mention, pushing the camera's sensitivity to a whopping ISO 102,400, although a monochrome rather than colour image is recorded.
The Exposure Compensation button is thoughtfully positioned next to the shutter release. Hold down this button with your right forefinger and spin the control wheel on the top-rear of the camera with your thumb to adjust its settings - simple and intuitive. The other buttons sitting next to the shutter release are the aforementioned Movie Record button and one for setting the metering. The D7100 has a similar monochromatic status LCD to the D90, a pro-level feature that indicates who this camera is primarily targeted at. On cheaper cameras, the LCD on the rear usually has to do both jobs, but on this model most of the key settings are visible from above on the smaller panel. This can make theNikon D7100
quicker to use and it may also extend the battery life, depending on how extensively you use the rear LCD screen.
The D7000's 16.2 megapixel CMOS sensor has been superseded by a 24.1 megapixel CMOS chip, capable of providing a Live View feed, recording Full HD video and capturing full-resolution stills at 6 frames per second for up to 33 Fine JPEG images and 6 14-bit RAW images, slightly more than the D7000 for JPEG but significantly less for RAW. There's also a slightly faster rate of 7fps in the new “1.3x” crop mode with an increased buffer of 73 fine JPEGs or 12 RAW files. The 1.3x crop function principally provides an additional 1.3x telephoto effect. As the Nikon D7100 is a DX camera with a “crop factor” of 1.5, the “1.3x” mode is in fact a 2x crop mode relative to 35mm full frame, essentially turning the Nikon D7100 into a 15-megapixel FourThirds camera while retaining the 3:2 aspect ratio. In this mode the camera's 51 focus points cover an even wider area of the frame for even better subject acquisition. It also allows for faster operation of up to 7 fps continuous shooting and Full HD movie recording up to 50i/60i.
