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

The Canon EF 16–35mm f/2.8L III USM is an indispensable ultra wide-angle zoom lens for professional and enthusiast photographers who demand superlative operation and performance, in virtually any condition. Its 16–35mm focal range provides superb control of perspective, helping you capture pictures and movies with amazing, dramatic compositions limited only by your imagination. Combining outstanding image quality, a fast, constant aperture and a rugged design, the EF 16–35mm f/2.8L III USM delivers eye-catching results whether capturing detailed, nuanced landscapes, dramatic interiors and much more. 

Ultra-Wide-Angle Zoom Lens

A wide-angle lens refers to a lens whose focal length shorter than a normal lens for a given picture plane. A wide-angle lens allows for more of the scene to be included in your picture. Wide-angle lenses allows for the photographer to get creative with the depth of field since the background can be made to look expansive and these lenses are great for scenic landscape photography, architecture and interior photography. The EF 16–35mm f/2.8L III USM has a bright constant maximum aperture of f/2.8, which provides superb control over depth of field and the ability to maintain the same aperture throughout the zoom range. This is particularly helpful when shooting outdoors at dusk or in inclement weather, or indoors in dimly lit rooms. At f/2.8, the EF 16–35mm f/2.8L III USM offers a bright view when composing images using the camera’s viewfinder.

All-New Optical Design

The EF 16–35mm f/2.8L III USM features a new optical design engineered to deliver images of remarkable clarity and depth – a magnificent complement to the large, high-resolution sensors in the SLRs favored by today’s advanced photographers. It employs two large-diameter double-surface GMo lenses plus a ground aspherical lens to help decrease distortion, curvature of field and astigmatism. Two UD lenses help to reduce chromatic aberration, leading to precise color rendition, accurate edge-to-edge detail plus excellent contrast throughout the lens’s zoom range. This means sharp landscapes, reduced distortion in the edges of the frame and an overall improvement in image quality no matter the subject.

Subwavelength Coating (SWC) and Air Sphere Coating (ASC)

The EF 16–35mm f/2.8L III USM features both Subwavelength Coatings (SWC) and Air Sphere Coatings (ASC) on its lens elements to help combat reflections, flare and ghosting, and deliver clean images with reduced aberrations from reflected light. Subwavelength Coatings help prevent reflections by arranging an array of wedge-shaped nanostructures on the lens’s surface that are smaller than the wavelength of visible light and are able to help control reflection and flare. Air Sphere Coating technology puts an ultra-low refractive layer on the lens element designed to significantly reduce both flare and ghosting. These coatings, in concert with the EF 16–35mm f/2.8L III USM’s overall optical formula, help to deliver a clean image to the camera’s sensor, which can decrease the need for post-production.

Highly Resistant to Dust and Water Intrusion

Befitting an L-series lens, the EF 16–35mm f/2.8L III USM is built to endure photography and moviemaking in even the harshest conditions*. It features a dust- and water-resistant construction on the switch panel, the zoom and focus rings, and on the lens mount, helping to prevent dust and moisture from interfering with operation. When outfitted with a Canon filter, the EF 16–35mm f/2.8L III USM is supremely dust- and water-resistant.

Rated 5 out of 5 by from One of my favorites This is a great lens. I previously had a 3rd party 14mm for wide angle use that I rarely used because of poor picture quality. First day using this, photos were colorful and sharp corner to corner.

Rated 5 out of 5 by from Essential element Took this lens to China and used it under various conditions from cloudy and misty to night to sunshine to fog/pollution and got wonderful results. Sharp shots even without IS and handheld. Shot pics at night going through the Gorges Dam. Paired it with a Canon 5d Mark III.
