What cameras fit the leica elmar m 24mm f 3 8 asph?
The Leica Elmar-M 24mm f/3.8 ASPH is a small, slow prime that's built for Leica M bodies and is one of the cheaper Leica wides on the used market. It fits a long list of full frame Leica M cameras, including the M9, M9-P, M (Typ 240), M Monochrom, M10 and M11 families, and the M EV1. The full list is on its catalogue page.
If you're after a camera to pair it with, I'd look at the Leica M10 or the Leica M11 for a modern body with the sensor and finish you'd expect at this price. Either way, it's manual focus only and not stabilised, so it suits people who enjoy focusing by hand. For a quick read on what a lens like this is good for, the lenses guide covers focal length and aperture in plain terms.
