Today Sony announced two small updated versions of their current a7rIII and a7rIV cameras. In both cases, the cameras get a small “a” suffix to their model numbers to differentiate them from their original predecessors.
According to the updated product specifications, both the a7R III (model: ILCE-7RM3A) and a7R IV (model: ILCE-7RM4A) have improved rear LCD panels, up to 2.36 million dots compared to the 1.44 million dots in the original models. Both cameras are now compatible with USB 3.2 (SuperSpeed USB 5Gbps). Sony notes in the battery life of the updated cameras has dropped slightly (10 shots) when using the LCD panel. Also, based on the product photos on Sony’s website, the a7R IV (model: ILCE-7RM4A) no longer has the Sony logo under the LCD monitor.
Sony’s updated product pages don’t show whether or not the price has changed and, as of publication, Sony’s site isn’t linking out to any retailers with the new models in stock.
