Atomos Introduce 4K Camera Recorder for the Alpha 7

by on August 7, 2014

There were a variety of exciting new 4K cameras showcased at NAB 2014. Among them were Sony’s Alpha 7 mirror-less camera and the Shogun. The Shogun is an all-in-one 4K HDMI Apple ProRes monitor-recorder.

If you have not heard of the Alpha 7, that is a 4K mirror-less interchangeable lens camera. It is the latest addition to the Sony a7-series, which also includes the a7 and a7R. As it has 4K video capture Sony have considerably bolstered the a7’s camera recording. The director of the interchangeable camera lens business at Sony stated:

The α7S gives Sony the most complete, versatile lineup of full-frame cameras in the market today. Between the α99, VG900, RX1, α7, α7R and now α7S 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.”

However, whilst the camera can shoot 4K videos, it cannot do so to its on-board SD Card. Consequently, an external recorder is required to attach to the top of the Alpha 7. The Shogun is the first such recorder for Sony’s Alpha 7. It is the world’s first 12G SDI & 4K HDMI I/O monitor recorder and deck that utilizes 4K output from HDMI cameras such as the Panasonic GH4, 4K SDI C500 and Alpha 7.

The Atomos CEO said of the Shogun: “Shogun is the culmination of everything we stand for, amazing edit codec’s from the sensor like 4K ProRes and RAW Cinema DNG. Affordable 4K recording through Raided HDD’s and SSD’s and unbelievable custom panels for monitoring. Super light and slim and at a price point under 2K. We offer a faster more affordable camera to timeline workflow with revolutionary 4K cameras from Sony, Panasonic and Canon.

Note that the Shogun’s monitor does not have a 4K resolution. It is a Full HD monitor with a 1,920 x 1,200 resolution. The Shogun’s 7-inch monitor offers both waveform monitoring and focal assist tools to capture shots.

The Shogun camera can record up to 120 fps in Full HD. With it you can record to single or raided HDDs or SSD storage devices. You can record up to two hours of 4K footage with two terabyte raided storage.
