Sony Alpha a7RII Mirrorless Camera has been announced with the world’s first full-frame 42.4-megapixel Exmor R back-illuminated structure CMOS sensor. This sensor design both improves low-light operation and speeds up data throughout, enabling fast high-resolution stills and UHD 4K video recording. Working with the BIONZ X image processor, these images can be produced at sensitivities up to ISO 102,400 and at a continuous 5 fps shooting rate. Five-axis SteadyShot INSIDE image stabilization has also been implemented, compensating for vertical, horizontal, pitch, yaw, and roll movements.

High Resolution, High Sensitivity and High-Speed Response
The newly developed 42.4 MP back-illuminated CMOS sensor is the most advanced, versatile and highest resolution full-frame image sensor that Sony has ever created, allowing the α7R II to reach new levels of quality, sensitivity and response speed. In the past, many photographers have been forced to choose between high-resolution and high-speed or high resolution and high sensitivity when selecting a camera. The new α7R II eliminates that sacrifice thanks to its innovative image sensor.
The 42.4 MP sensor combines gapless on-chip lens design and AR (anti-reflective) coating on the surface of the sensor’s glass seal to dramatically improve light collection efficiency, resulting in high sensitivity with low-noise performance and wide dynamic range. This allows the camera to shoot at an impressive ISO range of 100 to 25600 that is expandable to ISO 50 to 1024002.
Additionally, the sensor’s back-illuminated structure, with an expanded circuit scale and copper wiring design, enables faster transmission speed and ensures content can be captured in high resolution without sacrificing sensitivity. Data can also be output from the sensor at an approximately 3.5x faster rate compared to the original α7R.
An ideal match for Sony’s extensive collection of FE lenses (35mm full-frame compatible E-mount lenses), the new α7R II features a high-speed BIONZ X image processing engine that allows images and video from the camera to be captured with supreme details and low noise. There is also no optical low pass filter on the camera, ensuring that scenery and landscapes are captured in the highest possible resolution and clarity.
The α7R II has a new highly durable reduced-vibration shutter that realizes 50% less vibration from shutter movements compared to its predecessor, and has a cycle durability of approximately 500,000 shots4. The camera can also be set to Silent Shooting mode in order to shoot images quietly without any sensor vibration or movement.
The new image sensor features 399 focal-plane phase-detection AF points – the world’s widest AF coverage on a full-frame sensor1 – that work together with 25 contrast AF points to achieve focus response that is about 40% faster than the original model. The α7R II utilizes an advanced motion-detection algorithm combined with this Fast Hybrid AF system to achieve up to 5fps continuous shooting with AF tracking.
Additionally, the focal plane phase-detection AF system on the α7R II works well with Sony A-mount lenses when they are mounted on the camera using an LA-EA3 or LA-EA1 mount adapter. This allows users to enjoy the wide AF coverage of 399 focal plane phase-detection AF points, high-speed response and high tracking performance with a wider range of lenses. This marks the first time that the AF system of a mirrorless camera can achieve high performance with lenses originally designed for DSLRs.
5-Axis Image Stabilization Optimized for 42.4 MP
The new flagship α7R II model is equipped with an innovative 5-axis image stabilization system that has been fine-tuned to support its high-resolution shooting capacity. Similar to the system launched on the acclaimed α7 II model, this advanced form of image stabilization corrects camera shake along five axes during shooting, including angular shake (pitch and yaw) that tends to occur with a telephoto lens, shift shake (X and Y axes) which becomes noticeable as magnification increases, and rotational shake (roll) that often affects video recording. This camera shake compensation system is equivalent to shooting at a shutter speed approximately 4.5 steps faster5.
Additionally, the 5-axis stabilization works cooperatively with Sony α lenses with optical SteadyShot™ (OSS) to provide maximum stabilization and clarity, while also performing admirably via a compatible mount adapter with Sony α A-mount lenses6 without on-board stabilization. Effects of the stabilization can be previewed via live-view on the LCD or OLED viewfinder of the camera.
Unrivaled 4K Movie Shooting Performance
The impressive video credentials of Sony’s new α7R II camera include the ability to record movies in 4K quality (QFHD 3840×2160) in either Super 35mm crop mode or full-frame mode.
In Super 35mm mode, the camera collects a wealth of information from approximately 1.8x as many pixels as 4K by using full pixel readout without pixel binning and oversamples the information to produce 4K movies with minimal moire and ‘jaggies’.
In full-frame mode, the α7RII utilizes the full width of the 35mm sensor for 4K recording, allowing users to utilize the expanded expressive power of the sensor. It is the world’s first digital camera to offer this in-camera full-frame format 4K recording capacity1.
The camera utilizes the advanced XAVC S7 codec during video shooting, which records at a high bit rate of 100 Mbps during 4K recording and 50 Mbps during full HD shooting.
Additionally, the α7RII model features a variety of functions to support a professional video workflow including Picture Profile, S-Log2 Gamma and S-Gamut, 120fps high frame rate movie shooting in HD (720p), time code, clean HDMI output and more.
Enhanced Design, Operability and Reliability
The new full-frame α7RII has an upgraded XGA OLED Tru-Finder™ with a double-sided aspherical lens that delivers the world’s highest viewfinder magnification3 of 0.78x for crystal clear image preview and playback across the entire display area. ZEISS® T* Coating is also utilized to reduce unwanted reflections that interfere with the shooting experience.
The camera has an extremely solid, professional feel in-hand thanks to its light, rigid magnesium alloy design, and has a re-designed grip and shutter button compared to its predecessor. There is also a new mechanism to conveniently lock the mode dial, and an expanded range of customizable functions and buttons to suit the most demanding photographers.
The new α7R II camera is Wi-Fi® and NFC compatible and fully functional with Sony’s PlayMemories Mobile™ application available for Android™ and iOS platforms, as well as Sony’s growing range of PlayMemories Camera Apps™, which add a range of creative capabilities to the camera. For example, there is more creativity available now for time-lapse photography thanks to a new “Angle Shift add-on” app allows users to easily add pan, tilt and zoom to time-lapse images without any additional shooting equipment or PC software required.

Sony has also introduced a new LCD monitor model CLM-FHD5, an ideal companion to the α7R II for video shooting. A compact 5.0 type Full HD (1920x1080p) LCD monitor, the CLM-FHD5 features enlarging and peaking functionality for precise focusing, false color and video level marker for adjusting exposure and S-Log display assist to assist S-Log shooting.
