Leica noctilux m 35mm f 1 2 asph vs voigtl nder nokton 35mm f 1 2 aspherical iv?
These two lenses have identical listed specs: 35mm, f/1.2, manual focus, no stabilisation, for full-frame Leica M bodies. The site doesn't list prices or compare image quality, so I can't tell you which one is better or which is worth the money.
Both fit the same bodies, so the choice comes down to the lens itself. The Noctilux-M is the newer one, the first 35mm Noctilux, announced in 2026. The Nokton is a Voigtländer. Either one would suit an M11 or an M10, and both work on an M (Typ 240).
If you want a 35mm for people and groups, the portraits guide explains why it's a good focal length. For a broader kit, start with your first lenses.
