As to be expected of a lens that’s made for high-end, professional use, this fast telephoto zoom is as advanced as it gets. Optically it’s superb, combining high levels of sharpness with effective suppression of aberrations. Other desirable features include weather-resistant construction, autofocus that’s fast, silent and accurate, and effective optical stabilisation. A customisable control ring, two programmable buttons and a top-plate display panel provide an unmatched level of control. The result is a fantastic lens that’s ideal for a wide variety of uses, ranging from wildlife and sports to portrait and wedding photography.
