For japhotovideo - No adaptor is needed when an EF lens is used on Canon DSLR's, such as my 5D MkII or even a cropped camera like the 40D etc. Hope this answers the mail.

Hi I am just wondering where did you buy your adapter for the 5d mark 2, it says here that you used the 35 F2.0 lens.. This is a nice pic.. please email me TY
