Overview

The Quantaray 135mm f/2.8 MC is a manual focus telephoto lens. Optical strengths include good sharpness when stopped down, but wide-open performance may be softer. Chromatic aberrations are present, especially lateral CA at edges. Build quality is typical for its era, with all-metal construction and smooth focus ring. It suits photographers seeking an affordable 135mm prime for portraits or telephoto work, particularly on APS-C cameras, where its flaws are less apparent.
