Okay I'm sure its been discussed I just can't find it. I need memory for my new 5D mkll, what is the recommended cards and card sizes. My 5D Classic is perfectly content with San Disk Extreme lll and lV 4GB cards but the files sizes on the new camera have me a bit concerned. I have looked at San Disk's inventory and I can't decide if the 16GB Extreme Professional Grade is usable or do I need to go with the the Extreme Pro which is almost $100 more. I'd like this to economical but do not want to sacrifice quality.
Arguably, an 8GB card would give you approximately the same storage capacity on the 5DMKII as a 4GB on the 5D. I use the 8GB Sandisk Extreme 30MB/s cards on the Mark II for that very reason.
