A:AnswerI purchased 64gb SDHC, but it can take SD, SDHC, and SDXC all capacities. You can get micro SD, but you will need the larger sized converter for it to fit in the camera.
A:AnswerThe camera has built in WiFi, so if you have access to a WiFi service, you should be able to upload with no other device. I haven't specifically tried Facebook, but the WiFi does work.
