I think that instead of the Extreme III, you'll want to get a faster card with UDMA, such as the Extreme 60 MB/s UDMA (I use those in my 7D).


If you check out Sandisk's recommended cards for the 7D, you'll see only the Extreme 60 MB/s UDMA and Extreme Pro 90 MB/s UDMA cards on the list. UDMA cards provide faster burst capabilities for still shooting, and Canon recommends a UDMA card if you are taking still photos while capturing movies.
