The Z 6 is aimed at photographers who want excellent performance in low light conditions and 4K UHD video with full pixel readout. The 24.5MP CMOS backside illumination sensor with focal-plane phase detection AF pixels supports a wide sensitivity range of 100-51,200 ISO and works with the latest Nikon image processing engine, the EXPEED 6. The camera has 273 focus points, enabling broad coverage of approximately 90% of the imaging area, both vertically and horizontally. A mid-range sharpening option in the Picture Control menu allows users to make textural elements within the screen sharper or softer with both still and video imaging.
