^ Of course, the camera has to be able to quickly process the images as well before storing them on the card. H7 uses the BIONZ processor, same one used in its Alpha (DSLR) series.
I'm using original 2GB storage card by LEXAR.
BTW, I was just wondering....if the Canon and H7 both have same MP and CCD, the only difference remains in the lens...which isn't that bad in the H7 (its a Carl-Zeis with 'floating' lens system for image stabilisation).
