Best portrait lens for the leica m typ 240?

For portraits on the Leica M (Typ 240), I'd start with the Leica APO-Summicron-M 90mm f/2 ASPH. It's a classic portrait length on full frame, and the f/2 aperture gives you soft backgrounds without being fussy to focus.

If you want something more compact, the Leica Summilux-M 75mm f/1.4 gives you a similar look with more light-gathering, and the Leica APO-Summicron-M 75mm f/2 ASPH is a smaller, sharper option at a slower aperture.

For a wider, more environmental portrait, the Leica Summilux-M 50mm f/1.4 ASPH is the one I'd reach for first.

Whichever you pick, light matters more than the lens. Read the portraits guide for how to use a window or open shade, and see lenses if you're still building a kit.
