Well, this is a little strange. Sony has updated both the Sony A7R IV and the older Sony A7R III (which I didn’t realise they were still even making) with a new, higher-resolution LCD, bumping it up from 1.44 million dots to 2,359,296 dots. Both models also see a slight change in model name, adding an “A” to their previous ILCE designation.
Both cameras now also now say they support USB 3.2, although this is a little bit misleading because nothing’s really changed in the USB department besides the name. The specs say USB 3.2 “SuperSpeed” at 5Gbps. That means USB 3.2 Gen 1, which is the same as USB 3.1 Gen 1 or USB 3.0. It also means the same as the original A7R III and A7R IV.
