The Nikon D7200 is a 24-megapixel APS-C digital single-lens reflex camera announced by Nikon on March 2, 2015. It started shipping on March 19. It is the successor of the Nikon D7100 and has (among other things) the following enhancements:
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.
The optical CMOS sensor has been exchanged to a different model, which (unlike the D7100's) is not prone to generating faint striped patterns (banding noise) in night photography with strongly amplified dark tones (a scenario typical for Astrophotography).
Sensor-related image quality measures have been determined to lead the APS-C camera class (as of April 2015)
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.
The electronic processor has been updated, (EXPEED 4 replaced EXPEED 3).
Power consumption has been lowered, so that a battery charge lasts for typical 1110 exposures, which is 160 more than the D7100 under the same conditions.
Wi-Fi is now built-in, as is NFC, offering simpler smartphone connectivity.
The layout of the shoulder display has been simplified. Its overall size is the same as before, but some secondary information has been removed in favor for tidiness and for important items to appear bigger.
The back screen's visual interface has been changed slightly.
A new picture processing mode (called "Flat Picture Control"), which does not change the original tone reproduction curve, has been adopted from higher-end models. This is to benefit RAW and JPEG photographers and videographers, who prefer to see histograms and preview images with high tone fidelity during shooting of scenes with a high dynamic range, and prefer to postpone any tonal adjustments to later post-processing.
The maximum video quality mode (1080 lines/60 frames per second at a frame size reduced by the factor 1.3) has been improved to be non-interlaced (60p), where the D7100 was interlaced (60i).
Otherwise, it has also been described as "by no means a radical upgrade" compared to its predecessor, "yet it still adds some important features".
The camera body shape has been left unchanged, in particular the deeper-grip update of other latest models such as the D5500 hasn't been adopted for the D7200.
