About the Sony Alpha a7S
Shoot detailed photos, even in low light
Shoot detailed photos, even in low light
The Sony Alpha a7S is so compact, you wouldn't guess how much cutting-edge technology there is inside. The camera uses upgraded sensor technology to gather as much light as possible. The impressive direct pixel readout chip inside the camera is the same size as a full frame of 35mm film, allowing for high sensitivity and low noise levels with high dynamic range in every light condition from severe low light to bright sunlight. Sony's BIONZ processor makes sure beautiful photos emerge quickly.
The upshot of all that technology inside the camera? Every pixel is working at maximum efficiency, so you can shoot high-definition stills and let the camera convert the images for optimum playback on a compatible Sony 4K TV.
It's a high-quality video camera, too
The technological advances that make the a7S a great choice for still photos also make it an excellent video camera. Shooting in the AVCHD format with a speed class 10 memory card, the camera can capture full HD video at 1920 x 1080p resolution. If you're looking for the best possible image quality for your nature documentary or film school project, the a7S can even output uncompressed 4K video to an optional external third-party 4k recorder via HDMI. S-Log2 technology expands the camera's dynamic range by up to 1300% to minimize clipped highlights and loss of detail in shadows.
Easy uploads with Wi-Fi® and NFC pairing
The a7S also supports Wi-Fi and NFC (Near Field Communication). NFC provides a "one touch connection" with NFC enabled smartphones and tablets. The free Sony PlayMemories apps add functionality when downloaded, including the ability to control camera functions remotely via a compatible device.
