Sony Announces α7R II With Internal 4K Recording

By James DeRuvo (doddleNEWS)

Sony has announced the α7R II, a full-frame 4K mirrorless camera that comes with a 42.4 MP Exmor R CMOS sensor and up to 40% faster auto focus, plus a five axis image stabilization scheme. But the biggest feature may be its ability to record full-frame 4K internally.

The new α7R II interchangeable lens camera features the world’s first back-illuminated full-frame Exmor R CMOS sensor1, which realizes high resolution (42.4 MP approx. effective megapixels), high sensitivity (expandable up to ISO 102400)2 and high speed AF response up to 40% faster than the original α7R thanks to 399 focal plane phase detection AF points.

The camera also includes a 5-axis image stabilization system borrowed from the acclaimed α7 II model and can shoot and record 4K video in multiple formats including Super 35mm (without pixel binning) and full-frame format, a world’s first for digital cameras1.  Additionally, it has a newly refined XGA OLED Tru-Finder with the world’s highest (0.78x) viewfinder magnification3. – Sony Press Release


In addition to providing internal 4K recording, the α7R II can shoot in either Super35 or Full Frame format, making it the first camera to be able to switch sensor platforms on the fly. It also has a refined OLED viewfinder with a .78x viewer magnification. The α7R II also has a gapless on chip lens design which provides for higher light sensitivity without inviting noise to the party. This enables the α7R II to record in extreme low light situations, demanding an expandable ISO rating of 102400.

Sony has also refined the design of the α7R II’s circuitry in order to provide faster data transmission that won’t sacrifice sensitivity. The result is a data output of 3.5x faster than the original α7R design.

For film shooters, there is one feature that runners and gunners are sure to love. The α7R II can switch on the fly between full frame 4K recording and Super 35, a world’s first. In Super 35, the camera gives users nearly two times as many pixels for shooting in ultra high definition, without pixel binning.

It also oversamples the image information in order to eliminate the annoying moire and jaggies that can plague digital images. In Full Frame mode, the camera uses the full sensor to capture 4K internally, a first according to Sony. The α7R II also uses Sony’s advanced XAVC-S codec for video shooting at a high bit rate of 100 Mbps and 50Mbps for HD.

The α7R II also supports support a Picture Profile, S-Log2 Gamma and S-Gamut, 120fps high frame rate movie shooting in 720p, time code, clean HDMI output and more.

Other features of the α7R Mk. II include:

  • 42MP Full-Frame Exmor R BSI CMOS Sensor
  • BIONZ X Image Processor
  • 5-Axis SteadyShot INSIDE Stabilization
  • 399 Phase-Detect AF Points & 5 fps Burst
  • Internal 4K XAVC S Video & S-Log2 Gamma
  • Weather-Resistant Magnesium Alloy Body
  • Built-In Wi-Fi Connectivity with NFC
  • ISO 102,400
  • no shutter blade motion
  • 3,5x faster than the A7r
  • A7r II focus is almost 40% faster than the one of the A7r

The Sony α7R II will cost around $3200 and will be available in August.

Sony also announced a new α7R II compatible LCD monitor called the CLM-FHD5. A compact, 5-inch screen with full HD, enlarging and peaking functions, false color and video level markers for exposure adjustments. It also has an S-Log display assist for S-Log mode video workflows.
