We have now a fairly good amount of slow motion samples for the Sony a6500 compact APS-C Camera to share with you. It is clear that the quality this camera can provide is above the norm but we still do see some aliasing in diagonal fine lines which is to be expected by a sensor that is skipping some of the lines to achieve 1080p 120fps.
While the 4k UHD in this camera is derived from an oversampling of 6k; the 1080p 120fps is being extracted from a 24.2MP sensor using a 13MP effective crop factor 1.9x; is throwing away some line information to get there. Also the camera caps frame rate output over HDMI at 60fps so there is no way to record super slow motion to an external recorder at 120fps.
