Can I use adapted lenses on the sigma fp l?

I don't cover lens adapters on this site, so I can't tell you how an adapted lens will behave on the fp L. What I can tell you is what the site does cover.

The fp L uses the L-Mount, and the Sigma fp L page lists the lenses made for that mount, from Leica, Panasonic, Sigma, Samyang, Laowa and others. If you want a lens that's already designed for the camera, start there.

If you're thinking about a third-party lens, check two things first. Make sure the lens supports the autofocus features you need, and make sure the maker allows third-party lenses on that mount. The Lenses guide explains both.
