Full-frame sensor, Captures full HD 1080p video, Support for 4K The Exmor CMOS sensor and the BIONZ X image processor are well known for producing high quality video and still images with high dynamic range, low noise, and ISO sensitivity all the way up to 409600. This is one of the best mirrorless camera for video capture because the lower resolution sensor was designed for it. Higher resolution sensors are forced to skip lines to scale down to the necessary resolution for video, which contributes to undesirable effects like aliasing and moire. Since this camera's sensor does not skip lines, it produces very high quality video. It can't record 4K, but it can output 4K video (3840x2160) at 4:2:2 color depth over HDMI to a 4K video recorder.
