Sold internationally as "MF 50mm f1.8 Full Frame Lens With Shaped Aperture". Four built-in shaped aperture plates (heart, snowflake, oval, star) instead of a conventional diaphragm; F1.8 only. Bokeh shapes invert between front and back focus. Size excludes the mount. The distributor says "release without lens" must be enabled, so the lens has no electronic contacts.
