On the 5D (not sure about the Mark II, but at least on the original) the mirror is larger than on the other bodies from what I gather, and sometimes the camera has to be modified to handle certain Takumar lenses that have protruding rear sections.
The 1Ds II I have appears to have fewer clearance issues. While I haven't put any Pentax glass on it yet I am using a Tele-Lentar 135/2.8, a Jupiter-9 and a Zuiko 50/1.8 on it currently.
