Cameras (besides Canon) in order of most use:
Cosina Voigtländer (Bessa L)
Mamiya (645AF)
Kiev (88CM and 60)
Pentacon (6)
Petri (7s Rangefinder)
Nikon (Nikonos V, just got it from a mate but haven't even done a test roll yet)
Non-Canon Lenses in order of use:
Zeiss (mostly on the P6-variants, can't afford ZE prices)
Sigma (8-16mm gets a fair workout on the 7D)
Cosina Voigtländer (21mm f/4 is a damn fine lens)
RokiBowYang (35/1.4, thanks to Roger at LensRentals I can't call it anything else)
KMZ (for the soviet versions of the P6-mount lenses, plus the M42 Jupiter, Helios, Cyclop, Tair, and Mir)
Lensbaby (almost everything except the 80mm and 35mm)
... and various others, like Asahi Pentax (Takumars), Olympus OM macro lenses, Tokina (a little-used 17mm), a collection of Schneider Kreuznach for some of the Kodak Retina models, and some that I have no idea what they are or where they came from.
