It builds this subject-recognition system into its main AF system and will switch between subject-aware and generic (non-recognition-based) tracking, as needed. Remote camera operation using the optional wireless remote controller (RMT-P1BT) allows you to shoot effective stills while avoiding camera shake caused by pressing the shutter release.

The ability to shoot 4K in 10-bit 4:2:2 also gives color graders much more flexibility than on the Sony A7 III. There are two control dials, two buttons, the mode dial and the shutter release on the top of the camera to the right of the viewfinder.

Because it oversamples its 4K/30p video from the sensor's 7K resolution, you get an impressively sharp, noise-free image even up to ISO 12800. In our tests, it managed to shoot 4K/60p for two hours and 20 minutes with no overheating, and a few minutes longer in 4K/24p mode before the battery died.

It shoots in 12-bit mode and then applies visually lossy compression in its 10fps mode, which isn't going to make a lot of difference in a lot of instances, but means we're not going to declare it to be a great sports camera. To maximise the incredible resolution available to the α7R IV the tiniest vibrations need to be supressed, so Sony re-engineered the shutter unit assembly with dampened screws to absorb any shutter shock. I know how to "read" light and I don't need thousands of focus points or 37 different exposure modes to get it right. Dedicated street or sports photographers should look elsewhere, and it isn't the fastest shooter in its class.As far as the battery issue goes, at events where weight and power aren't an issue, carry all the batteries you need. million dots, the EVF is on par with cameras such as the Alpha 9 II and previous generation Alpha 7R III, however, it’s greatly surpassed by the 5.
