Sony Announces A7s Full-Frame Mirrorless Camera With 4K Video

Sony has announced the A7s, a new variant in its A7 line of full-frame interchangeable lens cameras. The new A7s is a more video-centric version of the A7, capable of shooting 4K video.

The A7s is equipped with a 12.2 effective megapixel 35mm Exmor CMOS sensor partnered with a BIONZ X image processor and the “s” in the camera’s name stands for sensitivity so the A7s is capable of a wide sensitivity range of ISO 50 – 409600. For comparison, the A7 is only capable of going up until ISO 25,700. It’s also equipped with S-Log2 gamma which expands the camera’s dynamic range by up to 1300% for minimizing clipped highlights and detail loss in shadows.

According to Sony, the A7s is the world’s first camera that uses the full width of the camera’s full-frame image sensor for 4K video capture without the need to crop or skip any lines of the sensor. While the A7s is capable of shooting 4K video, it will require a third-party external device for recording it. In-camera recording will be limited to full HD (1920 x 1080) video at 60p, 60i, 30p, and 24p.

The A7s is also capable of recording video at APS-C crop mode which will make the A7s capable of shooting at a high frame rate 120fps mode at a standard HD resolution (1280 x 720) for slow-motion video shooting. Sony has also added XAVC S format support to the A7s which allows for full HD recording at a data rate of 50mbps.

“The alpha7S gives Sony the most complete, versatile lineup of full-frame cameras in the market today,” said Neal Manowitz, director of the interchangeable lens camera business at Sony Electronics.  “Between the  alpha99, VG900, RX1, alpha7, alpha7R and now alpha7S 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.”

Sony also announced that they’re working on a new E-mount lens for the A7s, the lens is a full-frame power zoom 28-135mm F4 lens.

Sony didn’t announce a date of release or an SRP for the A7s or the new lens saying only that the information will be “announced at a future date.”
