7Artisans has teamed up with historic Chinese camera brand Seagull to launch a new limited-edition 35mm rangefinder lens for Leica M-mount cameras, and it might just be one of the most interesting affordable M-mount lenses we have seen this year. The new Seagull x 7Artisans M 35mm f/1.7 is a full-frame manual-focus prime designed for Leica M cameras, combining a classic 35mm focal length with a fast f/1.7 maximum aperture.
