Thanks to the help of a couple people on this forum I purchased a Sony HX300 as a gift. I also purchased a 64GB Sony Class 10 card (on a cyber Monday sale). The man at the store where I ordered my HX300 notified me that I need a special proprietary memory card called "digital speed" (I think). He said without this card then this camera won't be able to unlock all its features. Can anyone comment about this and please offer me help. Thanks!
