I have ordered a Mac Pro. I am wondering if I should upgrade the cable I use to upload pics to it since it has thunderbolt and USB 3.0 slots. If you know the fastest option, let me know. I saw that this lightning to USB adapt is for iPads. http://store.apple.com/us/product/MD821ZM/A/lightning-to-usb-camera-adapter?fnode=5b3abcc454654c56a0e1d775d3d6376db8041083c9ce7e2898d21e1eb184a3ad08b295a0f90c525399dc4295859b551fedf4e344b215f60796dcecee09fa49a6
I do not want to get a lighting to sd reader, since I will upgrade to a better camera in the future.
Buy the lexar or sandisk USB 3.0 dual card (cf and sd) reader. They are very fast, and as others have said, canon cameras don't have USB 3.0 output yet.
I have the lexar ($30) Here's what I do:
1. After shooting I pull the card (sd or cf) from the camera
2. Place card in USB 3.0 card reader and connect to MacBook Pro.
3. Transfer images
4. When done, keep images on card as a back up and place card in my camera bag
5. Place a different card back in camera for the next time you shoot. (You should have at least two, but preferably three or more cards)
