Ok, so I did some comparisons of the various Canon SLR's and their dimensions (actually, also checked out Nikon & Olympus). Easily enough, the New F-1 has the exact dimensions as the EF, except for 1mm taller, which obviously isn't a problem.

PLUS, they apparently made a half case w/o the tripod socket, which would've been a problem since the socket on the EF is off centered.

So basically, I can get a New F-1 half case and call it a day.

Thanks everyone!
