I'm thinking about purchasing 2-3 of their 8GB cards (they areofferinga rebate through March 28th). Currently I have a 20D, but will be upgrading to a 1DsMkII this year, and also using that body for an upcoming equine photography workshop. I shoot RAW, generally not in bursts, but likely will be shooting a lot of action at the workshop.


Thoughts on if this card will be appropriate? Or should I look into the Extreme IV? Thanks!
