thanks goatee, i just got the canon a while ago, and am still learning about it, and im kinda bewildered by the amount of gizmoes and gadgets out there, how do i find the compatibility? can most lenses be attached to my camerea, but the autofocus wont work? thats what im wondering, i know it may sound dumb, and soemthing that is obvious to you guys, i just dont want to spend money on something that wont work on my camera, all the stuff ive seen online isnt very user freindly, like the companies you order the stuff from seem to assume your going to know everything but theres stuff in my manual that doesent really tell me anything.....
