28–80mm · f/2.8–4
The Canon EF 28-80mm f/2.8-4 L is an old professional zoom lens that offers solid build and sharp optics, with a useful walk-around focal range. It suffers from distortion, particularly for architecture, and slow autofocus in low light. A major weakness is reliability: when the focus motor or aperture blades fail, repair is often impossible due to scarce parts, rendering the lens unusable. It suits budget-conscious users who can accept the risk of failure and lack of weather sealing.
