Canon EF 16-35mm f/2.8L III USM Ultra Wide Angle

The Canon EF 16–35mm f/2.8L III USM is an ultra-wide-angle zoom lens geared for professional and enthusiast photographers who want high performance in diverse conditions. This lens has a constant maximum aperture of f/2.8, which provides control over depth of field and the ability to maintain the same aperture throughout the zoom range. This feature is most helpful when shooting outdoors at dusk, in inclement weather, or in dimly lit rooms. Plus, its nine-blade circular aperture delivers soft backgrounds, while its new optical design with a high-resolution sensor provides clear images with improved depth. Subwavelength and air sphere coatings help reduce reflection, flare, and ghosting.
