Sony unveils the 42.4 MP a7R III mirrorless 4K camera.
As rumored, Sony has announced the a7R III, a 35mm full-frame 42.4 MP mirrorless 4K camera with a back-illuminated Exmor R CMOS image sensor. While the sensor is nearly identical to the a7R II, Sony improved 4K UHD shooting with a brand new Hybrid-Gamma Log profile and 15-stops of dynamic range. Sony is also claiming it has reduced noise reduction almost a full stop compared to the a7R II.
The a7R III offers internal 4K (3840×2160 pixels) in multiple frame rates up to 30 fps. When shooting in Super 35mm, the camera uses full pixel readout without pixel binning to collect 5K (15-megapixel), oversampling to produce its 4K footage. 4K recording has also been improved in the mid to high levels to use the entire full-frame sensor width. The a7R III can also record Full HD up to 120 fps. UHD 4K movies and lower-resolution proxy movies can also be simultaneously recorded.
