The Alpha A7 III sits on the bottom rung of Sony’s full-frame mirrorless camera range, and is designed to appeal to both keen enthusiast photographers and professionals. It’s no surprise to see 4K video capture on the Alpha A7 III. Recording in 24p, the full full width of the sensor is used, with full pixel readout and without pixel binning. It supports 4K capture at 60 or 100Mbps using the XAVC S 4K codec at your choice of 24 or 30fps. The 24fps video uses the full width of the frame, but there is a modest crop applied when shooting at 30fps. Dropping down to Full HD gives you 50 or 100Mbs options at 24, 30, or 60p, and there is an in-camera slow-motion option at 60 or 100Mbps and 120fps.
