A comparison of pictures taken with D3s and D7100 from same standpoint of a Black Redstart about 50 meter away. Lens, Nikon 800mm with 1,25 x teleconverter, implying 1000 mm focal length.

The D4 has 16 MP, not much more than the 12 MP of the D3s, as the D7100 has 54 MP in FX comparison.

The results clearly show that for birding, the D7100 sensor density is to be preferred. The test also reveals that the sensor of the D7100 fully matches the lens, and is not a "bottleneck".

Nikon should work for a D5 or D4x with 54 MP or even more, with cropping abilities down to 2x and high fps in cropped takings.

Here are the results. The first picture is a collage, showing the differences in sizes from the D3s and the D7100.

In addition a detailed crop of the Black Redstart from both cameras, revealing that there are full detalis in feathers with the D7100, but lack of details with the D3s. Both cameras have been AF-calibrated for the lens combination.

D3s increased to comparable size with the cropped D7100 portrait above.
