Hi everyone I have a 32 GB SanDisk micro SD which works fine and also a new Sony 64 GB micro SD class X which I can't get to work. It says SD card error(I noticed the other forum postings about this) and when I try to format the card it doesn't seem to help. Has anyone successfully used a 64 GB card with this camera? More google searches are showing that 32 is the max. Anyone had any luck? Should I format the card in my (Mac) computer first?
