Best DSLR: top cameras by price and brand
All things considered, Nikon has produced an attractive offering for enthusiast photographers that centres around the thing that these users value the most - detail. The Nikon D7100 produces sharp, detail-rich images straight from the camera and noise is well controlled up to ISO 6400.
However, as usual we wouldn't recommend straying beyond this value and into the expansion range.
Those who like to dabble in sports photography will also not be disappointed, provided you are happy to time your shots carefully and don't press the shutter release too early. The autofocus system is extremely capable and it gets the subject sharp even in quite low light. Thanks to the 1.3x crop, photographers can also get a little closer to their subject in-camera.
Image colours are typically Nikon-like, with the Standard Picture Control setting producing pleasantly vibrant images in most situations.
We usually recommend that you keep an eye on the histogram view when shooting to ensure images are correctly exposed, and this is sound advice with the Nikon D7100, since the Matrix metering system is prone to underexposing in some situations. But at least it protects the highlights.
Although Nikon has given the D7100 a pretty extensive feature set, it would've been nice if the company had pushed things a bit further and perhaps included Wi-Fi technology in-camera to enable remote control via a smart phone or tablet. At £649.99/US$642.96, the WR-1 wireless remote introduced at the same time is far too expensive for most users.
It would also have been good to have seen a touch-sensitive screen -preferably articulated like the Nikon D5200's - that is designed to complement rather than replace the physical controls.
So there are a few extra things we would have liked to have seen here. On balance, though, we think that the Nikon D7100 is a very nice camera that's enjoyable and rewarding to use.
