The Nikon D7200 is one of the best enthusiast DSLRs out there, and a
great choice if you’re looking to upgrade from an entry-level model.
It’s packed with features and has a cracking sensor, and offers solid
performance and an excellent AF system.
An improved buffer size that at its highest frame rate (6 frames per second) can store eighteen raw images (entire APS-C frame recorded, 14-bit lossless compressed), whereas the D7100 can store six images.
All 51 autofocus (AF) sensors have an improved performance at very low light scenes, with the effect of its light sensitivity being one exposure value
better (-3 EV) than the D7100 (-2 EV). -3 EV allows for autofocusing in
outdoor scenes only lit by the full Moon, or equivalently dark
artificial light or candle light scenes.
And 24.2MP CMOS sensor with no optical low-pass filter.
