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

By B&H Photo's

Characterized by a revamped optical design, the EF 16-35mm f/2.8L III USM from Canon is a workhorse wide-angle zoom and member of the well-regarded L-series of lenses. Featuring a series of specialized elements, this lens utilizes a trio of aspherical elements and two ultra-low dispersion glass elements to control a variety of aberrations for high sharpness and clarity. Both SWC and ASC coatings have also been applied to the elements in order to reduce lens flare and ghosting for increased contrast and color accuracy.

Complementing its optical prowess, a ring-type Ultrasonic Motor offers fast, smooth, and near-silent autofocus performance, which is further benefitted by full-time manual focus operation and an internal focusing design. The lens is both water and dust-resistant, and fluorine coatings have also been applied to the front and rear elements to protect against fingerprints and smudges from affecting image quality.

Wide-angle zoom 16-35mm lens is compatible with full-frame Canon EF-mount DSLRs, as well as APS-C-sized models where it will provide a 25.6-56mm equivalent focal length range.
Constant f/2.8 maximum aperture offers consistent performance and excellent light transmission throughout the zoom range.
Two large-diameter glass-molded dual-surface aspherical elements and one ground aspherical element help to minimize distortions and spherical aberrations throughout the zoom range in order to maintain edge-to-edge sharpness and illumination.
Two ultra-low dispersion elements are used to minimize chromatic aberrations as well as eliminate color blurring around the edges of subjects.
Both a Subwavelength Coating (SWC) and an Air Sphere Coating (ASC) have been applied to lens elements to reduce backlit flaring and ghosting for maintained light transmission and high contrast in strong lighting conditions.
A ring-type Ultrasonic Motor (USM), along with an internal focusing system, high-speed CPU, and optimized AF algorithms, are employed to deliver fast, precise, and near-silent autofocus performance as well as full-time manual focus override.
As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions.
Protective fluorine coating has been applied to the front bulbous element to resist fingerprints and smudges and to make cleaning significantly easier.
Rounded nine-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.

Great fast lens, no distortion. One of my primary workhorses, my kit wouldn't be complete without it.

This is the best lens I have ever bought and I wish I got it sooner. I also have the 16-35 f4 which is very good but the 2.8 ver 3 blows it away. I was actually not expecting this much of a difference based on the research I did prior to buying. I have a Canon 5DS-R (Canon's best camera for photography), and the combo produces beautiful images.

Excellent Wide angle!

I am a wide angle photographer, I Love Capturing the surroundings in a very symmetrical way, so I purchased this after market 14mm, its a hit and miss not so happy, I also have the canon 16-35mm 4.0 that I liked. I had the opportunity to borrow this 16-35mm 2.8 lll and Absolutely knew I had to have it! Great sharp images! I Highly recommend This version 100% if you are into wide angle shots.

Awesome!

A Great Lens

I have nothing but praises to Canon for this lens. This lens covers all of my wide angle needs. The lens has some vignetting in the corners, but it is to be expected in a wide angle lens. This can always be corrected in post processing. The vignetting, I have found, is sometimes desirable. Other than the aforementioned trait, the lens performance is superb. A Great Lens!

Will this lens work with EOS RP? I realize I would have to use the EF to RF adapter and am wondering any less of sharpness? Should I go with the RF 15-35 ; even though more expensive. I shoot landscapes and night sky.

I am considering the Canon 16-35 f/2.8 lens (or the f/4) for use on my 80D. In view of the reported severe vignetting would that be a problem with the 80D? It has the APS-C sensor which uses less of the image circle cast by the lens, especially in the corners. So I'm thinking it might be a good fit. I can up ISO by a factor of 2, minimum, to make up for the slower f/4 and get IS to boot while saving a bunch of money. But either lens could be acceptable. Any comments would be welcome.
Asked by: David
You would not see any vignetting when using this lens on a cropped sensor camera, it would work very well on your 80D.

Yes you will get distortion at 16mm -- standard for any zoom lens. It quickly dissipates when you get to like 20mm.
