Overview

The Petri 28mm f/2.8 Super Coated lens offers good sharpness when stopped down, with excellent contrast and well-controlled chromatic aberration and fringing. Flare is generally well controlled, though direct sunlight can cause contrast loss and hexagonal spots. Build quality is solid with smooth, well-dampened focusing, and it balances well on a camera. It suits photographers seeking a compact, manual walk-around lens for street or casual use, particularly on mirrorless bodies.
