As expected, Sony today unveiled the new Sony Alpha 7R IV full-frame mirrorless camera. The most important innovation is probably the completely new CMOS sensor with 61 MP resolution. The new Sony Alpha 7R IV achieves speeds of up to 10 fps including autofocus and exposure tracking with a maximum of 68 images. Following Sony&s example, the AF system of the Sony Alpha 9 has been integrated into the Sony 7 series with the new Alpha 7 IV.
In addition, the new Sony A7R IV provides video users with an eye AF function for the first time for the AF functions in video mode. The 61 MP sensor of the Sony A7R IV provides a total of 567 phase detection points, which comprise 74% of the image. In APS-C mode (26 MP-Crop) there are 325 AF points covering almost 100& of the frame.
8K video functions or codec updates up to 10 bits seem to have been missing with the new Sony Alpha 7R IV. Sony will save something for the upcoming Sony A7S III. Thus, the video functions remain at 4K 8 bit and S-Log 2 and 3. 4K is sampled down by a 6K full sensor readout.
We see the Sony A7R IV more as an evolution than a revolution. We are particularly excited about the AF performance and the viewfinder with its 5.76 million pixels (UXGA OLED) also promises to be interesting.
The new Sony 7R IV will be available from September 2019 for 3,500 dollars.
