Without a doubt, today was a day of premieres. The most important premiere was for sure the announcement of a new Sony A7r III, the camera for which we had to wait for 2 years, and about which we’ve been hearing rumors for the last few months. The newest camera is to have better image quality and it is supposed to be significantly faster and more effective than its predecessor.
The third generation of a full-frame mirrorless Sony camera is equipped with 42.2-MP CMOS Exmor R sensor, which was designed in BSI (Back Side Illumination – similarly to Nikon D850) technology. The sensor has 5-axis stabilization and is supposed to have the efficiency of 5.5 EV.
The sensor does not have a low-pass filter, which should influence quality and detailedness of photographs.
Pixel Shift Multi system is also used in the camera. It uses 5-axis stabilizer to take photographs with very high resolution. When you turn on this mode, the camera will precisely move image processor by 1 pixel, as a result of which four independent images, mutually moved by 1 pixel, will be registered. The images will have around 169.6 Mp altogether. Then these four images can be joined together in the mentioned “Imaging Edge” software package.

BIONZ X processor has been modernized when compared to its predecessor. It is supposed to be around 1.8x more efficient.
The camera can work within the ISO range of 100-32.000, which can be extended to ISO 50-102.400. 15-grade dynamic range in low sensitivities is also impressive.
With the use of the new camera, we will be able to take photographs with the speed up to 10f/s, with full focus and exposition automation, both in the mechanical shutter mode and in the electronic shutter mode.
The system of low-vibration shutter is also a novelty. It reduces the amount of vibrations and prevents image blurring in all modes, also during continuous shooting. During one series, one can take up to 76 JPEG/RAW photographs or up to 28 RAW photographs without compression.

Focus adjustment system in Sony AR7 III includes 399 phase-detection AF points placed in focal length plane, which cover around 68% of image area. 425 contrast-detection AF points are also available - 400 more than in the previous generation’s version of this mirrorless camera. The autofocus system also works in zoom mode.

When it comes to the construction, the camera has not undergone many changes. A direction joystick used to choose focus areas has been added. The body, similarly to is predecessor’s, is made of magnesium and it is fully sealed.
The camera is also equipped with a bright electronic viewfinder OLED Tru-Finder, with high resolution of around 3.686 million points. We can also choose the speed of its refreshing from 60 up to 120 fps.
The main screen has been designed in WhiteMagic technology, which is to improve visibility on sunny days. We can also choose the quality of the image displayed on a viewfinder and on the screen.
The camera also possesses 2 memory card slots, one of which operates with SD (UHS-II). Working time of a rechargeable battery has increased significantly, because the new camera is powered by Sony battery from Z series, which has 2.2 times more capacity than a rechargeable battery from W series, which was used in the previous body.

Many people will be interested in the film-making functions of the new Sony A7R III. The camera enables recording in 4K (3840x2160 pixels) with the use of full width of a full-frame image processor. A generated image is made smaller to 4K, which influences image quality in a very positive way.
In addition, we have gamma curves - S-Log2 and S-Log3. There is also a new HLG (Hybrid Log-Gamma) format which enables us to use “Instant HDR” work organization system in the camera and display 4K HDR images on the TV sets compatible with HDR (HLG) technology.
The camera also enables registering material in Full HD, with the speed of 120fps, with focus tracking.
