The Sony A7R III revolves around the full-frame 42.4-megapixel Exmor R CMOS sensor that works smoothly with the BIONZ X image processor to produce some of the most crystal clear results with impressive speeds. The copper wiring layers helps to enhance data transmission and makes the camera capable of 14 bit images. The camera works in all sorts of lighting conditions thanks to an ISO range of 100-32000 that can go as far as 50-102400. If you are dealing with fast moving objects the camera covers you there with 10 fps continuous shot for 76 consecutive frames.
The Sony A7R III employs the new 4D FOCUS system. This is a mix of 399 phase-detection points that stretch over 68% of the frame area. There are also 425 contrast detection points for swift autofocus and subject tracking. The Fast Hybrid AF system now means that focusing speed is twice as fast when compared to previous models even in low light as dark as -3 EV. The A7R III also has a 5.5-stop effective 5-axis SteadyShot INSIDE image stabilization that can reduce handheld camera shape to produce smooth gimbal-like video.
The Sony A7R III is as impressive with videos as with photos. You can shoot 4K UHD video at a frame rate of 30 fps. The camera makes use of Super35mm recording area and 5K resolution oversampled video to produce some of the clearest details on screen as there is no pixel binning. Other resolutions include Full HD 1080p at a staggering 120 fps for any slow motion videos. You get the option of 4x and 5x slow motion at 30 and 24 fps. Both of these resolutions make use of the 100 Mbps XAVC S format and 4:2:0 bit sampling. If you have an external recorder you can record uncompressed 4:2:2 bit video using the HDMI output.
The Sony A7R III has a new Quad-VGA OLED Tru-Finder EVF which has a 3.69m-dot resolution for crystal clear viewing even in bright settings. On the back of the camera is a 3.0″ 1.44m-dot rear LCD which also acts as a touchscreen for image playback and live view. It can also be used for intuitive focus control. The screen can be bent at various angles for better viewing. The body is made up of magnesium alloy and is weather sealed so you can work easily outdoors.
