    Overview

    The Vega-12 90mm f/2.8 is a Soviet medium-format lens designed for Kiev and Pentacon Six mounts. Optically, it produces sharp, contrasty images from f/4 onward, with slight softness wide open. Build quality is mixed; the aperture mechanism is prone to jamming. It offers a short minimum focus distance, adding versatility. Best suited for users comfortable with vintage Soviet lenses who prioritize optical performance over handling reliability.
