This Schneider-Kreuznach Symmar-S 135mm f5.6 lens is a relatively modern lens with multicoating and a good Copal 0 shutter. Compact enough for a field camera and in excellent condition overall, with no internal haze or fungus but a touch of that good ol’ Schneideritis at the element edges (it’s a flaw in the element rim coating- outside the optical path- that makes the blackened rim of the element look spotty). Includes retaining ring.
