Hi,

Through a series of adapters, you can put a wide range of Canon, Nikon, and other lenses on that camera. Rangefinders are great for this, because the distance from the lens flange to the film is narrow compared to an SLR. Same reason Canon FL and FD bodies are great for adapting other lenses to (but FL and FD lenses are not good for adapting to other SLR systems).

You will have to zone focus, of course.

I would first look into what adapters you can rig up. Then start looking for 24s. A 24mm 2.8 will be nice and small/light. Canon ones can be had for well under $50. They are probably one of the most common lenses Canon made after the various 50mm 1.8s and 1.4s
