A built-in 1.4x teleconverter instantly transforms this zoom into a 252-560mm f/5.6, while its constant f/4 aperture, one fluorite, and eight ED elements maintain clarity. Vibration Reduction stabilization and Nano Crystal Coatings ensure sharp, high-contrast images in demanding light and during handheld use. This lens is best for wildlife and sports photographers who need rapid focal length flexibility in a single, weather-sealed housing.
