If your lens is a Symmar-S 5.6 / 135 than the front filter thread is M49x0.75 (metric specifications - thread diameter = 49 mm ; thread pitch = 0.75 mm)

See the latest Symmar-S documentation in pdf here as of 1990

I have an Apo Symmar 5.6 /135 with the same filter thread M49x0.75. I have bought a step-up ring from M49x0.75 to M52x0.75 so that I can use M52x0.75 accessories, one of the most widespread filrre thread for 35 mm camera lenses.
