Leica summarit m 35mm f 2 4 asph vs ttartisan apo m 35mm f 2 asph?

Both are 35mm primes for full frame Leica M cameras, both manual focus and not stabilised, so the choice comes down to aperture and badge.

The TTArtisan APO-M 35mm f/2 ASPH is the faster lens. Its f/2 gives you more light and a bit more background separation than the Leica Summarit-M 35mm f/2.4 ASPH. I'd pick it for dim interiors or street work.

The Summarit is Leica-made, but it's from Leica's discontinued lower-priced line, so you'll be buying used. If the Leica name matters to you and you'll mostly shoot in good light, it's a sensible choice.

Both fit the same Leica M bodies, from the M9 through the M11 family. For how a 35mm behaves on people and groups, see portraits.
