Weighing just 508g, this lens delivers a 75-300mm reach in a package as light as a water bottle, making it exceptionally portable for an RF-mount telephoto zoom. Its constant f/4 aperture enables consistent subject isolation with blurred backgrounds across the entire zoom range without the cost or bulk of faster glass. This lens is best for budget-conscious EOS R series owners who want a lightweight, all-purpose telephoto for outdoor portraits and travel photography.
