Sony – for the first time ever – released a minor hardware upgrade to two long-ago-designed full frame cameras. The new version appears to be marketed as pretty much the old version, which makes sense given that the changes made are fairly minor. The back screen gains some resolution, and the USB connection is upgraded.

Sony makes some of the best – if not the best – LCD screens for cameras, but it stubbornly continues to opt to use cheap ones designed years ago for most of its professional cameras. The back screen on the A7R III and A7R IV will go from a terrible 1.44 million dots to a merely bad 2.36 million dots.

The changes do not appear to be designed to change the positioning of the cameras, but may instead be the result of happenstantial upgrades as manufacturing is adapted to parts availability and economies of scale.
