    Overview

    The Canon EF 28-300mm f/3.5-5.6L IS USM is a superzoom with excellent build quality and a versatile 28-300mm range, ideal for travel and events where lens changes are impractical. Optical strengths include good sharpness, contrast, and well-controlled chromatic aberration and distortion, though corner sharpness does not match primes or shorter zooms. The push-pull zoom is smooth but can be stiff and prone to dust ingress. It is heavy (3.7 lbs) and expensive, best suited for full-frame users who prioritize convenience over ultimate optical performance.
