理解中,會以慢嗰張嘅速度做寫入。

不過你都可以揀影相/拍片先寫兩張咭,咁可能會彈性大啲(e.g. A74可以快CFA拍S&Q,影相再同時寫CFA同SD)
Please note that if you want to shoot simultaneously to both card slots then there’s no benefit to using a CFexpress Type-A card in slot one, as you will alway be limited by the maximum speed of the SD card in slot two.
However, if you shoot in sort mode and record RAW images to slot 1 and JPEGs to slot 2 then there is still a benefit to using a CFexpress card in slot 1. Also providing you use a fast SD card such as the Kingston Canvas React Plus cards then you won’t hit the buffer shooting in Hi+ drive mode with compressed RAW images to slot 1 and JPEGs to slot 2.
