Canon Telephoto 420-800mm

★★★★☆ 4.1 (386)

Its 420-800mm zoom range and full metal construction deliver extreme telephoto reach for budget shooters, with manual focus only and an f/8.3-16 aperture. Built-in optical stabilization and multi-coated low-dispersion glass help reduce shake and aberrations on long-distance subjects. This lens is ideal for hobbyist wildlife and moon photographers comfortable with manual focus and looking to spend very little.
