This is a big wideangle lens for 4x5", with an unusually fast maximum aperture to making focusing and composing a breeze. Ample room for movements with 4x5" and can cover 5x7" when stopped down. Mounted in a Copal 0 shutter, healthy throughout its range of speeds. Aperture is smooth and glass is free of issues. There is notable body damage to the front housing and some cosmetic wear on the rear housing,
