In this Canon-compatible version, it stands out for its all-metal construction and streamlined ergonomics, much appreciated by wildlife and sports shooters who want to reach far without sacrificing robustness and consistent handling. This 500mm offers a maximum aperture of f/6.3 with precise, progressive manual focus designed for fine control at distance.
