CompactFlash is just about perfect to use in a camera in the field. As the size shrinks, so does one's ability to easily handle the card. SD is getting marginal as far as usability in the field. Forget about changing a Micro SDHC card unless you are back at your computer! Too small to handle and easy to drop and loose!However, with the 32GB and 64GB cards, that's not quite an issue especially if you leave the card in the camera! The camera is larger than the card my a great deal. Set it down and it's a lot easier to find and handle than a micro card (shown twice as large as life when I was writing this review).My cards came with SD adaptors so that they would be useable in my work flow, a plus. Also, within the adaptor, I can use the card in devices with SD slots and download using my existing readers.
