Overview

The Sirius 28mm f/2.8 MC Automatic is a vintage third-party lens with a 1:4 macro capability, offering a 300° focus throw and all-metal build that feels superior to some branded lenses. Optically, it has multi-coated elements but is soft and dreamy at f/2.8, improving when stopped down. It suits videographers on crop sensors who want cinematic close-ups with shallow depth of field, though it is not a true macro lens.
