Nikon D7100

The Nikon D7100 is a DSLR from 2013. Its body measures 136 x 107 x 76 mm and weighs 765 g. At its heart sits a 24.1 MP APS-C CMOS sensor paired with the Expeed 3 processor, and it uses the Nikon F DX lens mount. Framing is through an optical pentaprism viewfinder.

Autofocus is handled by 51 points, and burst shooting reaches up to 6 fps. The sensitivity range spans ISO 100 to 6400, with a top shutter speed of 1/8000 second. No in-body stabilisation is fitted.

Video tops out at Full HD, with built-in time-lapse available. Wi-Fi is built in, and two SD card slots are fitted.

The D7100 earns a good Optics score of 67, which places it around the middle of cameras in our database for Optics. Resolution is a clear strength, with the APS-C CMOS sensor supported by the Expeed 3 processor.

The autofocus system offers 51 points and the shutter reaches 1/8000 second, both scoring well. Native sensitivity spans ISO 100 to 6400, though the maximum sits modestly against scoring reference points, limiting the marks it earns. Base ISO 100 fares better, earning most of its points.

Continuous shooting reaches a maximum of 6 fps, though burst mode conditions and duration are not specified. The clearest limitation is the absence of in-body stabilisation, which earns no points here; that does not rule out stabilised lenses or tripod support.

Framing uses an optical pentaprism viewfinder, while the Nikon F DX mount handles lens attachment.

The D7100 offers video recording with a modest Video score of 57. Recording tops out at Full HD, and the maximum frame rate is 30 fps; the permitted combination of the two is not specified.

Both the resolution and frame rate earn partial credit against their scoring references, which accounts for much of the modest result. Built-in time-lapse is present and earns full marks, the only complete element of the video calculation.

Clips are recorded in MOV format. The specification score covers resolution, frame rate and time-lapse only; it does not test overheating, recording duration, codec quality or combined recording modes.

Live view is available for framing on the 3.2-inch LCD screen.

The Features score of 59 is modest. The 3.2-inch screen size earns full marks and its 1,228,800-dot resolution nearly so, while live view and weather sealing also score at or near their maximums.

The LCD is not touch-sensitive, and Bluetooth is absent; these two fields earn no points and account for the score's shortfall relative to a perfect result.

Beyond the scored items, other fittings are present. Wi-Fi is built in, GPS is absent, though phones or external taggers can still add location data. A built-in flash and external flash support are both fitted.

The screen does not flip away from the body, which limits overhead or waist-level framing unless the camera is repositioned.

The Storage and Battery score of 76 is good. Dual SD card slots earn full marks, accepting SD, SDHC and SDXC media. Whether the pair supports backup, overflow or simultaneous writing is not recorded, so those modes should not be assumed.

The EN-EL15 battery carries a 950-shot rating, earning most of its available points. The rating's test standard and shooting conditions are not specified, so it is best read as a nominal figure rather than a promise of real-world endurance.

USB charging is not supported, leaving a small share of the section's points unearned. No charging-while-shooting or power-bank arrangement is established by the specifications.

Taken together, full marks for dual slots and a strong battery rating outweigh the missing USB charging option, giving this section its good rating.
