It looks like the R&D department at Sony has no chill. That said, they have just proved that they are always a step ahead in the mirrorless full-frame camera world. Sony has announced the A7R IV full-frame mirrorless camera which comes with a monstrous 61-Megapixel sensor. Coming to the A7R IV its make a major bump to the resolution, from 42.4 MP to 61-MP. It also becomes the first full-frame mirrorless camera to employ a back-illuminated sensor with such a high resolution which promises the highest images quality from any full-frame mirrorless camera with less noise and increased sensitivity.

The sensor on the A7R IV promises a 15-stop dynamic range, which is more than Fujifilm’s medium format offering GF 50s and the GFX 100 for the matter of fact. However, it cannot be compared to the medium format offerings as it becomes a completely different category altogether. Sony has also added the 5-axis in-body image stabilization which ensures steady handheld shooting. To complement the new sensor, there is the addition of a new 5.76 million dot UGGA OLED EVF which is 1.6x times more than Sony’s EVF on the A7R III. It can be set to a standard or a high-resolution mode with an option of 60 fps and 120 fps refresh rate.

There are certain improvements, especially to the Pixel Shift Multi Shooting mode. It can stack 16 full-resolution images and merge them into a humongous 963.2 MP of data which is then finally output to a 240 MP image using Sony’s computer application. This allows you to take those crisp and detailed shots of non-moving subjects with even more improved colour accuracy and sharpness.

The A7R IV can shoot full-resolution 61-MP images at a rate of 10 fps with continuous AF/AE tracking. There are 567 phase-detection autofocus points that cover 74% of the image area. You get 425 AF points when using contrast detection. What you also get is Sony’s eye-af detection which we have seen works brilliantly and locks on to the subject.

The video department of the new A7R IV supports 4K video recording using the full width of the sensor and full pixel readout without any pixel binning in the Super 35mm mode. You get Sony’s S-Log 2 and S-Log 3 modes which open higher possibilities of colour grading with 14-stops of dynamic range available in the S-Log 3 mode. HLG is also supported for HDR workflow.

Sony has added the eye tracking AF in video, which is the first for a Sony camera. This allows the camera to track focus on the subject and keeps the eye in focus always while shooting video.

Additionally, it gets improved weather-sealing, a tilting touchscreen display, dual UHS-II memory slots, integrated digital audio interface on the camera’s Multi Interface Hotshoe, dual-band Wi-Fi, and USB Type-C 3.2 Gen 1

The battery on the A7R IV has a CIPA rated capacity of 670 images on a single charge and there is an optional battery grip which can hold two batteries. It has been priced at $3500 and will be first available in the US starting September. There is no word on its India launch and availability.
