I'm going to purchase a Canon 40D.My question is what speed and capacity CP card would you recommend.Thank you. <!--color-->
Considering how cheap the 4G cards are, I'd suggest you get one of those. e.g http://www.amazon.com/SanDisk-SDCFX3-409...9395&sr=8-1
is a 4G card for $59.
If you shoot RAW (or even worse- RAW+JPEG) then you should probably go for a 8G card e.g. http://www.amazon.com/Sandisk-Performanc...9549&sr=8-1
It's a bit slower than the 4G extreme III version, but unless you need those 6fps real bad, I think you'll appreciate the extra space.
Thanks very much for the information.
