Short and sweet: I run the card through a CF adapter also on my EOS 5D Mark II The card stores every task imaginable, indemnify and easily from, is recognized by all readers -. More can and I will not ask. Movies in HD quality have so far been up to min length turned 15, I repeat like: saving went smoothly. Visual aspects are mE completely irrelevant in the evaluation of this storage medium. If the card is so robust, as described - the better and reassuring all - I have not fully test before this. My full recommendation to camera users who want to experience not diminish due to low data transfer even when filming.
