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

The Canon EF 16‑35mm f/2.8L III USM is a high‑performance, professional‑grade ultra‑wide‑angle zoom lens designed for Canon EF‑mount full‑frame DSLRs. As part of Canon’s prestigious L‑series, this lens delivers superb optical quality, robust build quality, and reliable performance across a wide range of shooting conditions — from landscapes and architecture to events, travel, and multimedia production.

Exceptional Optical Design

Canon engineered this lens with a 16‑element, 11‑group optical formula that includes multiple aspherical elements and Ultra Low Dispersion (UD) glass to effectively control distortion, spherical aberration, and chromatic aberration. This design produces high resolution and accurate colors from the center of the frame to the edges throughout the entire zoom range.

Wide‑Angle Range & Constant Aperture

With a 16–35 mm focal range and a constant f/2.8 maximum aperture, this zoom lens offers excellent versatility and consistent performance in both stills and video production. The constant f/2.8 allows greater control over depth of field and improved low‑light shooting compared with slower zoom lenses.

Advanced Coatings for Clean Images

Both Subwavelength Structure Coating (SWC) and Air Sphere Coating (ASC) are applied to critical lens surfaces to suppress flare and ghosting under challenging lighting — such as when shooting toward the sun or bright light sources — ensuring strong contrast and clean images.

Fast, Precise Autofocus & Manual Control

A ring‑type Ultrasonic Motor (USM) paired with a high‑performance control CPU enables fast, quiet, and accurate autofocus for responsive operation. The lens also offers full‑time manual focus override, letting you quickly fine‑tune focus even when autofocus is engaged, which is particularly valuable when shooting video or precise stills.

Durable & Weather‑Resistant Construction

Built to Canon’s L‑series standards, the lens features dust and moisture resistance around key areas for reliable use in demanding environments. A fluorine coating on the front and rear elements helps repel water, oil, and fingerprints, making cleaning easier after outdoor use.

Smooth, Pleasing Backgrounds

A nine‑blade circular diaphragm yields smooth, pleasing out‑of‑focus areas (bokeh) and enhanced control over depth of field — even for wider scenes where selective focus is desired.

Reliable Performance for Professionals

• Ultra‑wide field of view ideal for landscape, architecture, and interiors.

• Weather‑sealed build withstands challenging shooting conditions.

• Fast f/2.8 aperture balances performance in low light with creative depth‑of‑field control.

• Advanced coatings reduce flare and ghosting for cleaner images.

Whether you’re shooting expansive landscapes, dramatic interiors, or cinematic video sequences, the Canon EF 16‑35mm f/2.8L III USM combines versatility, rugged durability, and Canon’s legendary optical quality — making it a reliable choice for professionals and serious enthusiasts.
