Well, this is unusual, although not all that surprising. I mean, it’s a surprise move, but if it had to be anybody… Sony likes to be different, especially when it comes to memory cards. According to a report on Sony Alpha Rumours, the Sony A7S III will be the first camera to use CFexpress Type A memory cards. It’s an odd choice, given that nobody makes CFexpress Type A, although it does make some sense.
They also say that it won’t quite be the dual card slots we’re used to. Instead of two separate slots for two separate cards, it’ll have a combination card slot of sorts, that can accept both CFexpress Type A or SD cards – although obviously not at the same time. Also, it might actually have a pair of these combination card slots.
