Back in April, Sony quietly updated its a7R IV, bumping the quality of its rear display and renaming it the a7R IVA, in keeping with manufacturers’ tendency to choose model names that follow no logic. The a7R IV has now disappeared from sale, and right now, you’ll struggle to buy either of these cameras.
Dan Watson explains the situation, outlining the improvement to the resolution of the rear LCD, with Sony increasing it from 1.44 million dots to 2.36 million dots and giving it better specs than the a7S III that was launched in October last year. A few other small changes are included in the a7R IVA: battery life sees a small improvement, and the USB port also receives a boost.
Price and availability will frustrate some buyers, but where it gets confusing are the product codes used by Sony. Searching B&H Photo for the a7R IV will only produce results for the a7R IVA. If you want to find the a7R IV, you will have to type in “ILCE7RM4/B,” where you will find that the camera is listed as discontinued. Given that it was launched as "ILCE7RM4," the /B has since been added to differentiate it from /A, one would assume.
That would all make sense until you realize that the updated version is not "ILCE7RM4/A" as you’d expect, but "ILCE7RM4A/B." To add further confusion, some retailers are listing the updated model not as the “a7R IVA” but as the “a7R IV (Updated Version).”
