New Sony alpha 7R II Mirror-less Camera is 4K Video Dream Tool

Sony unveiled their new flagship mirror-less camera with the Sony alpha 7R II. This new camera shoots 4K video with a 42.4MP sensor.

Sony has announced their new flagship full-frame mirrorless camera with the Sony α7R II (model ILCE-7RM2) with 4K video recording and a new 42.4MP sensor amongst many new advanced features that make this $3,200 camera prosumers dream.

The new Sony alpha 7R II interchangeable lens camera features the world’s first back-illuminated full-frame Exmor R CMOS sensor, which realizes high resolution (42.4 MP approx. effective megapixels), high sensitivity (expandable up to ISO 102400) 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 continues to deliver game-changing imaging products that are changing the way imaging enthusiasts, hobbyists and professionals can see and capture the world,” said Mike Fasulo, President of Sony Electronics.

Kimio Maki, Senior General Manager of Digital imaging Business Group for Sony Corporation, added “By harmonizing high resolution, sensitivity and speed, we’re delivering a high-level full-frame imaging experience unlike anything else in market today, with Sony’s newly developed, world’s first back-illuminated 35mm full frame CMOS sensor.”

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 new flagship α7R II model is equipped with an 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 faster.

The 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 α7R II 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 α7R II 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.

The new full-frame α7R II 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.

Pricing and Availability

The Sony α7R II full-frame interchangeable lens camera will be available in August for about $3,200.
