April 7, 2014: Sony has developed its new full-frame mirrorless camera known as ‘A7s’. This camera comprises of a 12.2 effective mega pixel 35mm Exmor CMOS sensor, which is also paired with BIONZ X image processor. It enables individuals shoot at a sensitivity range of ISO 50 – 4096002 with unprecedented dynamic range and low noise as well.
Its video modes can be changed from full-frame to APS-C (super 35mm equivalent). In its crop mode, the camera can support high frame rate 120fps shooting at standard HD resolution (1280 x 720p), creating a 5x slow-motion effect.
7S can output 4K video4 at QFHD (3840x2160) to an optional external 4K recorder. Adding to this, it can also record full HD (1920x1080) at frame rates of 60p, 60i, 30p and 24p directly to a compatible memory card.
Official reports also stated ‘The 12.2 MP sensor in this camera also helps to collect dramatically more light than traditional cameras and to produce beautifully detailed, low-noise images in even the darkest environments.’
Equipped with S-Log2 gamma, its dynamic range is expandable up to 1300% to minimize clipped highlights and loss of detail in shadows. This model also adopts the workflow-friendly XAVC S recording format in addition to AVCHD and MP4 codecs. This will help photographers with full HD recording at a data rate of 50 mbps with lower compression for improved video quality.
"The A7s gives Sony the most complete, versatile lineup of full-frame cameras in market . Between the 99, VG900, RX1, 7, 7R and now 7S models, we have completely revolutionized what it means to be a 'full-frame' camera, bringing a new level of quality and portability to enthusiast photographers and videographers," highlighted Neal Manowitz, Director of the interchangeable lens camera business at Sony Electronics.
