Schneider-Kreuznach XENON-EMERALD 50mm F2.2 Schneider Xenon Emerald "M Mount Modified" Leica M Mount Prototype Used only once after purchase and then stored in a dry cabinet. Currently satisfied with my existing lenses, so I'm selling it to organize my equipment. The body is lightweight and has good resolution from the open aperture, and sharp rendering when stopped down. Reportedly has the same resolution as the apo componon 45mm F4.
