NTx, good info but I need clarification. You said “larger card” and “card size” but how do you know the size? It sounds like for my purpose it doesn’t matter but I’m curious. GB is “memory” size I guess, but that’s not what you mean, correct? On some they have another number “MB”, is that the size reference, or speed. Dumb it down somebody.


Sorry. By size I meant data storage size rather that physical size. One gigabyte is equal to 1,024 megabytes (MB) and one megabyte is equal to 1,024 kilobytes (KB). Think of it as inches being MB and feet being GB. You want GB. Back when low resolution cameras were common, a person could use a SD card in MB, but with modern high resolution cameras, you would fill a MB card up quick. 32GB is a good all around card for modern cameras that isn't near as expensive as the larger cards.
