Canon Mark 3 video
I spend a lot of time, trying to find a information, about recommended minimum speed for recording full HD all-i video. It's clear, that SD card slot is not fast enough, i know there isn't possible to to gain over 133x at SD slot. But how fast the CF card should be? I don't want to spend money on expensive 1000x Lexar or Sandisc cards, unless i have to. Is 400x card will be enough?
I will not use the cards for ML Raw video, only for 1080P ALL-I
