Best portrait lens for the leica m10?
For portraits on the M10, I'd choose the focal length first, because the lens matters far more than the body. Three good options from the catalogue:
- Leica Summilux-M 50mm f/1.4 ASPH: fast and versatile, good when you want some of the setting in the frame.
- Leica APO-Summicron-M 75mm f/2 ASPH: a tighter, flattering framing for head and shoulders.
- Leica APO-Summicron-M 90mm f/2 ASPH: my pick if you mostly shoot close portraits and want the background to fall away.
Light still counts for more than any of these. Face a window, turn your subject a little, and expose for the face; the portraits guide has the details.
Keep in mind that M lenses focus manually, and the M10 has no in-body stabilisation, so keep your shutter speed up.
