Overview

The Revuenon 135mm f/2.8 Auto is a well-built M42 lens with solid metal construction and smooth controls. Optically, it is soft in the center and very soft in the corners wide open, with chromatic aberration and low contrast; center sharpness improves by f/4, but corners remain poor. Flare handling is poor, producing large rainbow arcs. Bokeh is smooth and pleasant. It suits photographers seeking a characterful, budget-friendly telephoto for portraits or creative work on mirrorless cameras.
