FYI You get (significant) diminishing returns on cards that are arates to have a write speed of more than 45Mb/s. (Based on the canon 6d and 5d3 tests) Shall link the research and data that I came across when I get the chance.
In my opinion, don't worry too much about card speed for now. Most of class 10 cards from reputable brands are good enough, and you can always upgrade later.
Thanks everyone for the help!
I shall close this thread!!
thank you very much!!
Enjoy your new cam (whichever model it is) & happy shooting!
