Overview

The Sirius 28mm f/2.8 MC Automatic is a vintage third-party lens with solid all-metal build and smooth, long focus throw. Its macro mode offers 1:4 magnification, useful for close-ups on crop sensors. Optically, it is soft and dreamy wide open, with improved sharpness when stopped down. Chromatic aberration and flare are present but manageable. Best suited for users seeking a characterful, budget wide-angle for video or creative photography.
