Sony A7s Announced, Price, Specs, Release Date


Sony A7S 1
Sony A7s has just announced, a 12MP full-frame mirrorless camera designed for both stills and video. The camera can read out its entire sensor fast enough to output 4:2:2 4k video over HDMI at up to 30p, without the need for line skipping or pixel binning. This also promises higher quality for the 1080p video (at up to 60p) it can record internally. Unlike the A7 and A7R, the latest model is not constrained by the AVCHD standard, also offering the XAVCS system, with bitrates of up to 50Mbps.
