„The Sony A1 and Sony A9 III both receive Relay Playback, a feature that streamlines the way you play files back when you have a memory card in each slot. As of now, when you're playing back from one card, you need to go into the menu to shift to the other card. Following the update, there will be seamless playback from the cards in slot one and slot two.“
