ARGH! no! curse SD cards, they are useless!!1!! Self proclaimed compact flash fanboy I really haven't paid any attention to that model to be fair, It just never struck me as anything interesting, just assumed it would be CF as its kind of a logical progression from the 400.
I thought SD was a huge PRO in a camera, and thought of getting the 450D. Luckily I found out the advantage of CF before buying one.
Likewise, I always saw CF as the bulky old method that the industry wont drop. So much more than that.
Luckily, moving over from an old ixus 500, i have plenty of CF cards knocking around Thanks for all the replies guys, i have been having fun over the last week with my new camera, and i really cannot wait untill exams are over and i can get shooting properly!
