The Sony A7R IV A is now officially available for pre-order at FocusCamera, but this curious piece of photographic tech is best described as an incremental update to the original Sony A7R IV. Featuring the same high-powered 61MP full frame Exmor R sensor and 4K HDR video capabilities, the Sony A7R IV A's updates concern the physical body of the camera instead. With added USB 3.2 support and an increase in screen resolution, we'd recommend plumping for the 'A' variant if you're interested in purchasing the Sony A7R IV.

The Sony A7R IV A features the same high-speed BIONZ X image processor and in-body 5-axis image stabilization that's found in the original Sony A7R IV. However, those aren't the only features that remain the same. The Sony A7R IV A essentially retains all of the internal technology of its predecessor, but bumps up the screen resolution and provides USB 3.2 support as well.
However, there is a small trade-off for these added features. According to Sony Alpha Rumors, Sony A7R IV A has a slightly reduced battery life than the Sony A7R IV, delivering 660 shots instead of the 670 on the A7R IV. However, with a difference of just 10 shots, we would still see the Sony A7R IV A as the better choice.
