Overview

The Soligor 135mm f/1.8 is a vintage manual-focus preset lens with a Sonnar-type design (5 elements in 3 groups) and a 16-blade aperture for smooth bokeh. Optically, it shows acceptable sharpness wide open that improves when stopped down, but chromatic aberration is present, though less aggressive than the f/1.5 version. Distortion is low. Build-wise, it is significantly lighter and more manageable than the f/1.5, allowing handheld use. It suits photographers seeking a fast vintage telephoto with character for portraiture or creative work, accepting its optical compromises versus modern lenses.
