Overview

The Topcor Macro-Topcor 135mm f/4 is a coated triplet bellows lens praised for its macro capability and compatibility with Topcon helicoids for infinity focus. Optically, it delivers sharp results at f/8–f/11 but exhibits noticeable chromatic aberration wide open. Build is solid, typical of manual-focus era lenses. It suits macro enthusiasts and those seeking a compact, affordable legacy lens for close-up work, though CA may be a concern for critical use.
