Sony Alpha 7s and Shogun

We asked Michael Bubolo, one of Sony’s engineers, to go over the specs of the Alpha 7s at NAB2014. He also spoke about the ATOMOS Shogun 4K recorder and the XLR adapter.

Here are the product descriptions mentioned in this interview:

The Atomos Shogun 7″ 4K HDMI and 12G-SDI Monitor & Recorder combines a color-calibrated 1920 x 1200 resolution display with 4K video recording and edit-ready codecs. The Shogun utilizes 4K HDMI and 12G-SDI inputs to record clean output signals at resolutions up to UHD 4K (3840 x 2160) at 23.98, 24, 25, 29.97, and 30p, as well as Full HD (1920 x 1080) video up to 120 fps when used with capable cameras.

The Shogun records 10-bit, 4:2:2 UHD 4K and HD video to Apple ProRes HQ, 422, or LT formats. It can also record HD video using Avid’s DNxHD format, and UHD 4K raw video using the uncompressed Cinema DNG Raw format. Video is recorded to single or raided 2.5″ HDD and SDDs for fast and reliable write speeds.

As a monitor, the Shogun features a 7″ IPS capacitive touchscreen display with resolution of 1920 x 1200. It is Rec. 709 color calibrated and supports multi-frequency operation (48/50/60 Hz) for monitoring and playback of a variety of input frame rates. An SDI loop output is available for passing the signal to an additional monitor.

Joining the acclaimed α7 and α7R family of the world’s smallest full-frame interchangeable lens cameras1, Sony’s new α7S model puts extraordinary sensitivity, low noise and spectacular 4K video quality into the hands of professional photographers and videographers.

The innovative α7S camera features a newly developed, 12.2 effective megapixel 35mm Exmor® CMOS sensor paired with a powerful BIONZ X image processor, allowing it to shoot at a sensitivity range of ISO 50 – 4096002 with unprecedented dynamic range and low noise.

The new model is also the world’s first camera to utilize the entire width of a full-frame image sensor in 4K video acquisition, and does this without cropping or line skipping as it can read and process data from every one of the sensor’s pixels. This allows 4K video shooters to utilize all of the artistic and creative benefits provided by the unique sensor.
