Yeah any micro sd card will work. Micro sd vs sdhc vs sdxc is just about maximum available storage capacities, sd the lowest and xc the highest. Just figure out how much storage you want. Micro’s are also cheaper than regular cards. I’ve always used regular (not micro) sandisc 16 gb sdhc cards in my camera’s and I’ve never had problems with sandisc. I prefer not to lose 32 or 64 gb’s of photos for whatever reason, I’d go just a little less crazy losing 16 gb’s of a days photos before getting them off the card and into an external drive.
