Independent testing by Gerald Undone using Imatest software and a Xyla color range chart demonstrates a dynamic range of 12.8 stops of light, which is approximately 1/3 of a stop better than the Sony A7s iii and approximately the same as the Sony a1. [17] It color matches fairly well with the Sony A7s iii and Sony a1, with the Sony A7s iii leaning a bit green, the Sony a1 a bit magenta, and this camera between the two (tested using DCS Labs -SW - CDM 28R - v15.2 A3 color chart) and with individual white balancing, the colors are very similar. [17]
Camera is using in house developed AVC Video Format called XAVC. The format is compressed format achieving balanced quality and file size. Recording in color depth of 10-bits and 4:2:2 chroma subsampling is possible with Sony's XAVC codec.
