I try to buy a new memory card for my Olympus Stylus 1200 and I am confused about the M and M + cards. Does anyone know the difference. I wanted an 8GB card but I can not find. Can you help me?

M was the original. M + is 1.5 times faster than M and H cards are three times faster than cards M.
The maximum size is 2GB.

Some devices have problems with M and H cards .... but your camera is fine with all the flavors of the card.
