step up in telephoto reach from 70-200mm f/2.8 ‘trinity’ zooms, this is something newlenses have come and gone. The Canon lens is nearly a kilogram lighter than the Sigma Sports lens, although still weighty at 2,590g and much more pricey. Highlights include super-fast Dual Nano USM autofocus, 5.5-stop optical stabilization and top-class L-series build quality and handling. It’s ideal for indoor or floodlit sports, wedding and event photography but has less telephoto reach than any other lens in this test group.
