Description — Canon EF 17-35mm f/2.8 L USM
The Canon EF 17-35mm f/2.8 L is a full-frame wide-angle zoom lens for Canon EF-mount DSLR cameras. It spans a focal length range of 17mm to 35mm, covering a broad wide-angle perspective that suits architecture, interiors, landscapes, and environmental work. The lens maintains a constant maximum aperture of f/2.8 throughout the zoom range, providing consistent exposure settings as you adjust focal length.
Both autofocus and manual focus are supported, offering flexibility across different shooting scenarios. The 77mm filter thread accommodates a wide range of polarizers, ND filters, and other accessories. At 545g, the lens has a solid, professional feel while remaining practical for field use.
Note that this lens has no image stabilization, so steady shooting in low light will rely on the fast f/2.8 aperture. It is designed specifically for the Canon EF mount and the DSLR camera system.
