Overview

The Steinheil München-Cassarit 135mm f/4.5 is a compact triplet lens with 13 aperture blades and a weight of 260g. Optically, it is a typical triplet design, which may produce distinctive bokeh but is often criticized for its rendering. Build quality is simple and lightweight, with an M42 mount. It suits photographers interested in vintage triplet characteristics or collectors of classic German lenses, though it is not highly regarded as a general-purpose telephoto.
