The new Canon 6D uses SD cards instead of the old reliable Compact Flash cards. Is this a good choice and do you think Canon will be using the SD cards in their upcoming cameras ? As far as I know SD cards are now comparable to compact flash as far as speed. Not only that, they are more popular and sell at retail stores like Radio Shack in varying sizes. I had problems trying to find Compact Cards greater than 2GB at Radio Shack. SD card are used in more electronic devices such as cell phones and MP3 players. But all this popularity makes me think of consumer Gizmos for the masses. One thing Compact Flash card have going for it is that my desk top computer has a slot for Compact Cards not SD cards and they seem to be more rugged. Can anybody think of any other adavntages the Compact Card has over the SD card ?
