Of its predecessor camera have inherited a full-frame image sensor type CMOS back-illuminated (BSI CMOS) resolution 42,4 MP without low-pass optical filter. At the same time, the addition of BIS interface, the use of more powerful Bionz X processor and improved processing algorithms have improved the speed of the camera. In particular, the burst speed increased from 5 to 10 fps. continuous shooting Speed in Live View is 8. the Maximum length of a series of 87 shots in RAW format with compression, or 28 without compression.

According to the manufacturer, the dynamic range of the camera reaches up to 15 stops of exposure. Specify that it is achieved with 14-bit data representation, which is not available in all modes. In particular, the continuous shooting with a maximum speed running, saving images in 12-bit format without the compression.

The system of automatic focusing includes 399 points of phase focusing, covering 68% of the frame, and 425 points contrast focus.

The camera is equipped with image stabilizer, the efficiency of which the manufacturer estimates at the 5.5 level of exposure (stabilizer Sony a7R II saves up to 4.5 steps).

The camera supports shooting 4K video. Available shot using the whole width of the sensor or using a window size 5176 x 2924 pixels (Super 35mm size frame is close to APS-C) with conversion to the resolution of 3840 x 2160 pixels.

In equipping the camera can distinguish the presence of the USB connector and the micro-USB connector and two SD card slots, one of which supports UHS-I, and the second — UHS-II.

Significantly increased autonomy without recharging the battery the camera allows you to make 530 images using the electronic viewfinder or even 650 shots using the LCD screen, and not 290 as in the case of the Sony a7R III.
