Nikon Coolpix A sensor test results came out


In the recently released DxOMark laboratory nikon DX format portable digital camera Coolpix sensor test results, A comprehensive score 80 points, and the nikon D7000 flat.

Coolpix carrying A and D5100, the D7000 specifications the same 16.2 million pixels APS - C sensors, including 23.4 bit color depth 13.8 EVs, weak sensitivity, dynamic range, ISO 1164, evident from these results, the three actual gap is very small, but the result has been more than the vast majority of portable digital camera, even without the camera.


DxOMark also notes that while ahead of Coopix A nikon D5200, D7100 and pentax K - 5 series, but as A portable digital camera, Coolpix A photo quality is close to or beyond the introductory many DSLR, in the end, it also makes it to the top ten places in APC - C.

It is also a minimum APS - C in the history of the camera. If we use one sentence to summarize the nikon COOLPIX A (hereinafter referred to as the nikon small A) what are some of the characteristics, that is the smallest APS - C in the history of the camera, of course you want to do this is not too easy, quite apart from what other design, APS - C sensor itself has very big size, so the sensor flange distance can not be too small (at least 2-3 mm), so big of the sensor can directly lead to the lens volume increased, so the APS - C camera I want to be thin, really difficult.

To control volume, nikon had A lot of kung fu is not only in terms of the overall circuit, the lens is also specially designed, nikon small A 18.5 mm f / 2.8 lens specifications, 7 pieces of 5 groups took seemingly very simple design, although in theory exceed short flange lens is better to do it, but digital sensors for the vertical incident light, and the vertical incident will greatly increase the lens size, it will give this camera increased A lot of problems.
