Frequent issue: Trying to make an SD-card work in a CF-card slot by inserting card into an adapter. Frankly, most adapters are just crap. There are some adapters able to work with ML's method of checking for a bootable card. But most will just get your cam stalled. It is strongly recommended **not** to use SD-to-CF adapters with Magic Lantern. ML project does not support it and in case of failure you won't get any help.\\ | Frequent issue: Trying to make an SD-card work in a CF-card slot by inserting card into an adapter.

Don't get me wrong, most current available UHS-II cards do perform pretty well in UHS-I compatibility mode and are only a tad slower compared to fastest UHS-I cards. But you have to take special care if you select UHS-II cards for your UHS-I camera if you go for performance. And most benchmarks available on the web don't make a difference and test UHS-II mode only. | Don't get me wrong, most current available UHS-II cards do perform pretty well in UHS-I compatibility mode and are only a tad slower compared to fastest UHS-I cards.
