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.

Pricey; Omits image stabilization; Some distortion and vignetting visible in images

But to be honest, I didn't know what to expect from the beta version of the Canon 16-35mm f2.8 L USM III lens that I tried.

Exceptional Autofocus and sharpness. Replaced 3 of my other dedicated focal length lenses quite easily.

I traded in my 24-70 zoom for this lens, am though my other lens for very good, this is even better, especially for wide angle close ups, it's superb. Obviously I use it with my full frame SLR and it's a great match.

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. Many of the issues such as coma, chromatic aberration and corner sharpness have all been addressed in this update and the results are impressive. 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.

Low-light event photography, landscape, cityscape and architectural photography and those looking for a wide-angle zoom option for astrophotography.;
