Sony Alpha a7s Mirrorless Digital Camera

The Sony Alpha a7s Mirrorless Digital Camera is a 12MP full-frame camera designed for both stills and video. The camera can read out its entire sensor fast enough to output 8-bit 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. The latest model is not constrained by the AVCHD standard, also offering the XAVC S system, with bitrates of up to 50Mbps. 

The 'S' in the camera's name denotes 'sensitivity'. In movie shooting, it offers an ISO 200 - 102,400, with extension to 409,600. In stills it offers ISO 100-102,400, extendible to an ISO 50 - 409,600 range. The camera's large pixels will offer good dynamic range, graduation and colour fidelity for still shooters. 

Built-in Wi-Fi connectivity, with support for NFC, is available for instant sharing of imagery from the camera as well as remote camera control from a linked mobile device.
