I have just unwrapped my shiney new EOS 5D MkII. (I could go on about it all day), With it I bought a SanDisk Extreme 60 Mb/S 8 Gb CF card. I chose SanDisk because in MY opinion you just can't get any better. And I chose 8 Gb 60 Mb/S after a phone call to Canon asking there advice. I am now thinking of a couple of "Back up" cards and think that I should go for 2 X 4 Gb (They seem big enough for my requirements, and if something tragic happens I have only lost 4 Gb of date.. Has anyone with experience of this set up got any advice about the speed of the card I should be getting. (The guy at Canon was a really nice lad, but gave me the impression that his idea of a "Prpoer camera was something his girlfriend could put in her clutch bag...) cheers folks Tim H.
