Panasonic has a Class 10 32 GB SDHC card. It's almost $300. Does it offer any advantage in the EX1/EX3? A friend has an EX1 and he occasionally has problems with his Sandisc Class 4 SD cards. Am I correct in assuming that the Class 10 Panasonic cards will be more reliable? Is it fast enough to over crank as well?
