I am looking for advice on a few items for my new Canon R5. I am mostly shooting stills with my telephoto lens. I have been using my existing ScanDisk SD cards but read that the CFExpress is essential in read/write speed for both still and/or video. Looking for advice on which SD and CFexpress cards to buy for ample results. Since I don’t intend to shoot video any time soon, I am mostly interested in a product to support my photography. What is the ideal read/write speed for photography only? Thanks in advance.
