Summilux 1.4/50mm chrome prototype

An interesting prototype Summilux 50mm with a serial number from the prototype Summarit 1.4/50mm range, but already engraved with the Summilux name. The lens shows some rare and unique features, like the special aperture ring with engravings similar to prototype Summarit 1.4/50mm lenses, '1.4' engraving on the depth-of-field scale or the focusing mount finished partially in aluminium, unusual feet/meter progression. The offered Summilux is in beautiful, near-mint condition, with excellent optics, it is one of the most interesting prototype lenses we've seen!
