I have some questions about the E-M1 II and the use of SD cards, that I'm hoping someone can answer for me. I'm aware that on the E-M1 II, only slot 1 is UHS-II compatible. I'm also aware that video can be recorded to one card, and stills to the other. My question is, has anybody tested it to prove that Cinemak 4K video can be recorded to a U3 UHS-I card? It should be possible, because U3 UHS-I cards guarantee a minimum write speed of 30 MB/s, or 240 Mbps, and the C4K codec the E-M1 II uses has a max bitrate of 237 Mbps, so in theory a U3 UHS-I card should be able to handle any 4K video the E-M1 will record. My question is, has anybody done this, tested C4K to a U3 UHS-I card in card slot 2, and can confirm it records without issue? If so, then my plan would be to record RAW images to a UHS-II card slot 1, and 4K video to a larger capacity (i.e. 128GB) UHS-I card in slot 2. Thanks in advance.
