Overview

The Prinzflex 135mm f/3.5 Auto Reflex is a telephoto prime lens for M42 mount SLRs, manufactured by a Japanese ODM and sold under various brands. Users report good results stopped down to f/4, with pleasing bokeh and a cinematic feel. However, copy variation exists; some find it soft even stopped down. Build is typical of its era, and it works with adapters on modern DSLRs, though metering quirks may occur. It suits budget-conscious photographers seeking a vintage 135mm look.
