I have camera bodies devoted "mostly" to certain types of film. I designate some cameras "color" cameras and some "black and white" cameras. Some "high-speed" cameras, some "low speed" cameras. For example, the Lynx 14 I own sees mostly Tri-X, that I develop in Diafine because of its unique f1.4 lens on a leaf shutter rangefinder. The Konica Auto S3 is for color street stuff, simply because I really like how that one renders colors and is very compact. Etc., etc...
