Canon EF 16–35mm f/2.8L III USM Lens, Black (0573C002)

The Canon EF 16-35mm f/2.8L III series lens is the successor to the EF 16-35mm f/2.8L II series lens. It's vastly improved image quality and superb contrast make it a worthy upgrade, if you have the extra cash to upgrade, or are buying a 16-35mm for the first time. The II series has soft corners, and exhibits way too much vignetting, IMHO, at 16mm. The III-series lens, shows very little. The saturation and contrast of the lens is superb. The III is heavier, longer, and larger in diameter than the II-series version, in addition to being more expensive. But those are the trade-offs for improved image quality. If you liked the II series version, I have no doubt you'll love the III series. Highly recommended.

This is my 11th L lens. For many years I thought I didn't need a 16-35mm, and only recently I started evaluating this glass. With the 11-24mm, the 35mm and the 24-70mm I initially believed there was no need for an additional lens in that range. Then I started comparing the 2.8 mark III vs the f 4.0, and eventually decided to go for the extra stops.Used it for the first time for an entire weekend and found it a perfect solution for what I frequent try do: landscape and urban exploration. While not an expert, I feel pictures are very sharp and the focal range covered is perfect for what I do, avoiding the extra complexity of the 11-24mm in terms of wait, size, lack of filter support and inevitable distortion in the foreground. While I will continue to use the 11-24mm in the foreseeable future, I have the impression this 16-35mm will become my preferred choice in many situations and circumstances. Super flexible, is an excellent compromise offering great quality at every focal length. So far, out of 440 shots, 156 at 30+mm, 140 <+200mm, 76 in the 26-28mm range and the rest distributed homogeneously.

From what I understand, this is one of the holy trinity of lens when it comes to Canon, the others being the EF 24-70mm f/2.8 and EF 70-200mm f/2.8. It's the second lens of it's kind that I've bought and is perfect for wide angle shots and landscapes without compromising your aperture. You might need something just a touch wider if you're doing real estate photography and are shooting a small bathroom, but otherwise, this lens has you covered.

Only wish it was cheaper. Other than that, everything else worked as advertised.

After first renting this lens from Lensrental.com for a gig I decided to buy this bad boy. Sure it weighs more than the same Mark ii version but so what? I had the Tokina 16-28 mm a few years ago and that's just as heavy and whatever abut the thing NOT flaring. Loved it but half my shots had a JJ Abrams flare going on.Someone wrote a review saying this Canon Mark iii lens flared and so far not one flare so I don't believe that and I've already shot about 500 shots on it. Love that the corners don't creep and the glass produces such sharp corner and beautiful picture. In a nutshell I LOVE my new lens after two weeks and I'm a pro who's shot 16 going on 17 years. Buy it for wide angle and landscaping shots plus indoor house photography. Heck, use it anyway you want and just buy insurance in case you drop it as it's a bit of a dime.Yes it's expensive but I'm going to be using it for years to come , it comes with a sweet leather bag and a Canon lens hood. L series is finally catching up on Nikon with the L series and this bad boy proves it.

This lens is truly amazing. I tested it quite a bit prior to a mountain trekking trip and found it to be sharp at all apertures and focus distances, unlike the mk1 version that I also own. I subjected this lens to days of hiking in dusty mountains and jungles and it always performed well. It is also comfortable to wear since the lens does not extend to zoom or focus.

I have 30 years of photography experience going back to the 4x5 camera days. Until this lens I have never been happy with the sharpness of any digital lens. This lens is tack sharp like the old Linhof Schneider lenses. Corner to corner sharp. No chromatic aberration problems that seem to plague the rest of the canon line. Hopefully a 24-105mm lens will be the next on Canon's sharpness upgrade.Buy this lens. It is worth the upgrade from the previous 16-35mm and it is light years better and worth every dollar that you waste on that crappy 17-40mm lens.

This is an awesome lens. I use it for real estate photography and sharpness is phenomenal.
