Can I use adapted lenses on the sigma bf?

The site doesn't cover adapted lenses, so I can't tell you how any particular adapter works with the BF. The BF uses L-Mount, and the Sigma BF page lists plenty of native L-Mount lenses from Sigma, Panasonic, Leica and Samyang, plus budget options from 7Artisans and Viltrox. Those are the simpler route.

Keep in mind that the BF has no stabilisation in the body, so slow shutter speeds will depend on stabilised lenses. The Lenses page also has a useful rule: check that a third-party lens supports your body's autofocus, and that the maker allows third-party lenses on that mount.
