The Canon 16-35mm F2.8L II has been one of the most coveted lenses amongst landscape photographers for a fairly long time. The legendary sunstar was one of the major selling points of the lens and it was one of the major characteristics that really separated the Canon lens from the rest of the field.

When we first heard that Canon was going to release an updated version of the lens we were pretty darn excited. The Mark II was a fantastic piece of glass, but struggled in terms of corner sharpness and control of chromatic aberration along the edges and in the corners of the frame. The upgraded version of the Canon lens promised to correct a number of those issues while still holding onto some of the characteristics of the previous version that made it so appealing to landscape shooters around the world.

With that said, the real question is; how does the updated Canon lens compare to its predecessor? The previous iteration of this lens had a number of issues that we will discuss in this review while we compare and contrast the two versions. The fundamental questions that we will be addressing in this review is; if the upgrade warrants the price increase and if the performance from the new design is convincing enough to justify the upgrade.


With an equivalent focal length of 25.6-56mm and an equivalent aperture of F4.5 there are better wide-angle APS-C options on the market such as the Tokina 11-16mm F2.8 AT-X116 Pro DX II Lens or the Sigma 18-35mm F1.8 Art DC HSM that can really take advantage of a fast aperture for a fraction of the price. For this reason we're not going to consider this lens for use on the APS-C platform in this review.
