    If you are shooting HD video, you definitely need high speed CF memory. This CF is on Canon's list of tested CF memory cards.

    they gotta get rid of this style of memory card. The contacts are THE WORST. I messed up the inside of my camera because I was not careful enough - completely my fault and there is nothing wrong with the card itself. Its just the design is terrible and after some internet searching in not the only one that feels this way. Anyway, I was able to straighten out the contacts with a tiny flathead, but i am too scared to take the CF out for fear of not being able to get it back in...
