About this model
The Canon EF 16-35mm f/2.8L II USM is a professional ultra-wide zoom from Canon's L series. On a full-frame body it covers a dramatic 16mm wide-angle to a natural 35mm, ideal for landscapes, architecture, interiors, events and astrophotography. The constant f/2.8 aperture keeps shutter speeds up in low light and lets you shoot starry skies, while the ring-type USM motor focuses quickly and quietly with full-time manual override. Built to L-series standards with weather sealing (when a front filter is fitted), it is a tough, reliable lens that has been a favourite of wedding and landscape photographers for years.
