Late February 2013 Nikon Corporation introduced the successor of the popular Nikon D7000, the D7100. This sophisticated camera has a lot of features in common with his ancestor, but a bit larger: the CMOS sensor has 24.1 effective Mp. instead of 16.2 Mp., the LCD screen has become the largest so far with 1,229k dots + an extra OLED display under it. The AF CAM-3500DX sensor - however - has less pixels but offers 51 AF-fields and makes it possible to measure light with lenses stopped down to f/8. Making a HD-movie with stereo sound is possible as well. A more important innovation is the extra switch-on crop factor of 1.3 over the standard 1.5 crop factor in comparison to the regular 35 mm frame (24x36 mm.), which creates a total crop factor of 2. The most significant feature is - however - the absence of an optical low-pass filter (OLPF), which most digital cameras have to avoid Moiré*-effects. Without such a filter the captured images may be even a bit sharper.
* Moiré - French for 'flamed' - is the nonlinear interaction of optical patterns of lines creating a real and visible pattern of roughly parallel dark and light bands: the moiré pattern.
