It uses the centre 1920x1080 section of the 4096x2160 image sensor chip, which leads to a much narrower field of view. It is primarily intended for slow motion playback (@30fps ?). I've not used it other than a quick test. Because of the speed the ISO tends to be high, and with a slowest shutter of 1/60th Sec'. Lots of light needed otherwise a bit noisy.
At the slower frame rates it would appear to use 2x2 binning of the whole chip (bunching together the pixels to turn a 3840x2160 matrix into a 1920x1080 matrix) which would improve the light gathering capabilities (like having bigger pixels). |
