Overview

The Pentax S-M-C Takumar 135mm f/4 Macro is a lightweight, portable lens praised for sharpness and contrast, especially at smaller apertures. It uses a Dynar/Heliar design. Its macro capability is limited to 1:3.2 without extension tubes; 1:1 requires tubes, which darkens the viewfinder. It suits portrait, landscape, and close-up work, though it may be too sharp for some portraits. A tripod is recommended for best results.
