Canon has released the EF 70-300mm f/4-5.6L IS USM, aimed at being an affordable ‘L’-grade telephoto lens. It offers a ring-type ultrasonic autofocus motor, weatherproof construction, claimed four-stop image stabilization and a minimum focus distance of 1.2m, all in a package about the same size as the existing EF 70-300mm f/4-5.6 IS USM. Additional features include an 8-bladed circular aperture, full-time manual focus override, and an optional tripod mount ring.
