The new Canon EF 16-35mm f/2.8L III USM is an outstanding but also very expensive ultra-wide-angle zoom lens that will appeal most to landscape, reportage and wedding photographers looking for a well-built, weather-proof optic with the main advantage of a fast and constant f/2.8 aperture for...

The updated Canon 16-35mm F2.8L III offers some incredible performance wide open at 16mm. It's one of the sharpest wide angle zoom lens options on the market.

The lens does suffer a bit in terms of sharpness at focal lengths beyond 24mm, but many of those issues can be resolved by stopping the lens down. If you're in the market to upgrade your 16-35mm F2.8L II or if you're looking for a fast wide-angle zoom, then this lens is an excellent option.

I've owned all 3 iterations of Canon's 16-35 mm f:2.8 L zoom. The first model was okay for its day, and rendered good 'sunstars' in backlit images, but resolution was just adequate for 8 mp sensors and corners tended to go soft with color fringing at most apertures.

very good

This is an incredible lens. I haven't had the opportunity to try the previous-generation models. Even at 16mm, the vignetting is very muted, and what little there is adds to the look of the photos. I'm extremely pleased.

Love it, best one for pros and so much better in low light!!!!

Great pictures and a good wide-angle

Don't feel as good build quality as my EF70/200mm f2.8 is usm mk2 lens

I use this lens with a 5D Mk III. I spent ages wondering about buying it as an upgrade to my old F4 L series lens covering the same range but decided to "go for it" ahead of a big trip to New Zealand.
