In the interest of full disclosure, I'm a PR rep for Lexar. Congratulations on purchasing a 7D. The 7D is UDMA-6 CompactFlash compatible, meaning it can take advantage of UDMA memory cards, which provide faster transfer speeds, both in the camera and when moving images to your host computer for editing (if used with a UDMA-compatible card reader). Lexar offers a number of UDMA CF cards you could consider, including the Lexar Professional 600x CF (available in 8GB. 16GB and 32GB capacities), the Lexar Professional 300x CF card (4GB, 8GB and 16GB capacities), and the Lexar Professional 233x CF (available in 8GB). You should also consider a UDMA-compatible card reader. Both the Lexar Professional FireWire 800 CF reader and the Lexar Professional USB Dual-Slot reader are UDMA compatible. Good luck on your purchase!
