Q
I bought a kingston canvas select class 10 memory card. the first day all ok. next day when a tried to film in 4k show me card speed slow error. why??
Answer Question
A
If a class 10 doesn't work, use a UHS 3 rated memory card. (On the card it looks like a U with a 3 in it instead of a C with a 10 in it). The UHS3 is much faster. The class 10 didn't work in mine either whereas the UHS3 works great.
A
Probably bad card. I would go with a good name branded card that is class 10 U3
