Overview

The Prinzflex 135mm f/2.8 is a vintage M42 lens, likely made by Komine (Nittoh Kogaku) in the 1970s. Optical strengths include lovely bokeh wide open, but it may have a slightly non-standard thread requiring an adapter. Build and handling are typical of the era. It suits photographers seeking a fast, affordable telephoto for creative use, though alternatives like the Tamron 135mm f/2.8 are also available.
