New versions of the a7R III and a7R IV cameras have recently been launched by Sony with little-to-no real fanfare.
The addition of a new “a” has been added to the official product name that differentiates them from the originals, so the a7R IIIa and the a7R IVa respectively. The new cameras appear to feature a few small cosmetic changes along with noticeable improvements to specific hardware, according to a press release from Sony.
An extensive upgrade to the rear LCD resolution might be the largest change here, which jumps from 1,440,000 dots to 2,359,296 dots. The Sony logo under the LCD monitor is apparently gone, but that doesn’t seem like a big deal at all. The USB port, however, has been upgraded to USB 3.2 “SuperSpeed USB 5Gbps.”
