Can I use adapted lenses on the leica cl?
I don't cover adapted lenses on the Leica CL, so I can't say from this site whether they work or how well. What I can tell you is that the CL uses the L-Mount and takes TL and SL lenses. Its full lens list is on the Leica CL page, and it covers everything from fisheyes to 600mm-equivalent zooms, so you may find what you need there without adapting anything.
If you're thinking about a particular adapted lens, check the lens's own page on the site for its mount and details before you buy. For general advice on choosing a camera and lens, start with cst1 likes cameras.
