All I know is that this is a smaller camcorder…in direct competition with the JVC HM100/Panasonic AG-HMC151 and I will stick my neck out by telling you that it may use Memory Stick DUO Pro HG. It may be 1/3″ chips but I suspect 1/4″ to accommodate the size, 1/3″ would be more preferable but it may also have the Exmor R chipset the one I was expecting to see on the EX-1R…this would set it above the competition.
