Sony tends to stick to its own standards, and this was also the case with recording media for digital cameras. In the early days of digital cameras, they developed Memory Stick, which was used as the recording media for their digital cameras. Although it was a small, stable and excellent recording media, unfortunately other digital camera manufacturers did not adopt it. Other manufacturers adopted CF cards or SD cards as recording media. However, Sony stuck to Memory Stick, and it was much later that they adopted an SD compatible slot. The new recording media standard that Sony adopted was the CFexpress Type A card. While other manufacturers were using CFexpress Type B cards, it seems that Sony decided to adopt Type A, prioritizing small size. They adopted an SD card compatible slot to avoid inconvenience to users, but once again other manufacturers have not followed suit. At present, only Sony digital cameras use Type A cards. Will Sony continue to use Type A cards, or will they switch to Type B? Adapters that allow Type A cards to be used in Type B slots will likely be available, but it will be interesting to see whether this will lead to a gradual switch to Type B.
