What cameras fit the leica noctilux m 50mm f 1?
The Noctilux-M 50mm f/1 is a manual-focus Leica M lens, so it fits any Leica M body, and all of them are full frame. The catalogue lists about twenty of them, from the Leica M9 through to the Leica M11. If you're buying one, the Leica M10 is a good middle choice from that range. You'll be focusing by eye, so the viewfinder and your own focusing skill matter more than autofocus. The full list is on the Leica Noctilux-M 50mm f/1 page.
