TTArtisan's ultra-compact M-mount pancake — 28mm f/5.6 in body-cap dimensions for Leica M.
The TTArtisan 28mm f/5.6 is an incredibly thin pancake prime for Leica M-mount — barely thicker than a body cap. At f/5.6 it is deliberately slow, relying on deep depth of field for zone focusing — a street photography concept.
Optically basic — designed for zone focus at f/5.6 where depth of field is enormous. The slow aperture means almost everything is in focus from a few feet to infinity. Sharp enough from f/8. The concept is simplicity — no focusing needed.
Leica M mount. Near-body-cap thickness. Zone focus marks — set to 3m at f/5.6 and everything from 1.5m to infinity is sharp. No rangefinder coupling on some versions. All-metal construction. Filter thread on most versions.
Available used at budget prices. The f/5.6 is deliberately slow — the concept is point-and-shoot street photography with infinite DOF. For Leica M street photographers wanting the most discreet possible lens — barely visible on the camera.
