This is the standard lens for 4x5 cameras. It is compact, sharp and has excellent image quality. It comes on a Copal No. 0 shutter.
This lens is in good condition and works perfectly. The glass is clean and scratch-free with no haze nor fungus. There is moderate fading of the masking paint on the edges of the glass, often called "Schneideritis." This is just cosmetic and does not affect image quality. The shutter is strong and accurate at all speeds. The lock nut is included.
