Konica Hexanon 50mm f/1.8 AR mount - Excellent condition, with no lens scratches or fungus. Aperture blades are nice and snappy. Focus ring action is smooth. It looks like there is a small mark in the rear lens coating, but does not affect photos. This is the metal barrel version, not the later plastic version. Comes with generic front and rear caps. Serial 7061392. Only slightly (~5mm) taller and heavier than the 40/1.8 pancake. This was the smaller and lighter replacement for the legendary 50/1.7 in Konica's lineup. You don't read much about the 50/1.8 because it wasn't produced for very long before Konica got out of the SLR business. But honestly based on several test shots comparing the two 50mm lenses I don't see any difference in color rendering or sharpness. $30, I'll cover Paypal fees and shipping to your door (USA). (in the lineup shot, it is in the middle between the 40/1.8 and the 50/1.7).
