Overview

The Raynox Polaris 135mm f/1.8 is a fast telephoto lens in M42 mount, sold under various brands. Its optical performance is typical of vintage fast 135mm lenses, with moderate sharpness wide open and improving when stopped down. Chromatic aberration and flare can be issues, but it offers a unique rendering with smooth bokeh. Build quality is solid, with a metal barrel and smooth focus ring, though it is heavy. It suits enthusiasts seeking a fast portrait lens with character, especially for adapted mirrorless or DSLR use.
