Canon EF 16-35mm f/2.8L III USM Lens

The Canon EF 16-35mm f/2.8L III USM is a full-frame wide-angle zoom lens built for Canon’s EF mount DSLR system and positioned within Canon’s L-series lineup, representing the higher tier of Canon’s optical and mechanical standards. Covering a focal range from 16mm to 35mm with a constant f/2.8 maximum aperture throughout, it addresses wide-angle applications including landscape, architecture, interior, environmental portraiture, and event photography where a fast, high-quality wide zoom is needed. The third-generation optical formula delivers improved resolution and corner performance compared to its predecessors, and the ring-type USM motor provides fast, quiet, and precise autofocus performance suitable for both stills and video use. Aspherical and UD elements help control distortion, aberrations, and chromatic aberration across the zoom range, and dust and moisture resistant sealing throughout the barrel adds reliability in demanding outdoor and professional shooting environments.
