The updated cameras now have an ‘a’ appended to their model numbers to differentiate them from their original predecessors.According to the update 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. Sony notes in the 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. Aside from those details, it’s not clear what else, if anything, has changed.Note the ‘Sony’ underneath the LCD panel on this product image of the original a7R IV.Note The lack of the ‘Sony’ logo under the LCD panel of the newly-updated a7R IV ‘a’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. Neither Adorama or B&H Photo have the new models listed as of publication. This, combined with the fact Sony hasn’t actually changed the more general name of the cameras will likely lead to some confusion for buyers, so you might want to hold off if you’re hoping to get one of these updated cameras until more information is available.We have contacted Sony for more details and will update this article accordingly when we receive a response.
