Canon 17-40mm f/4L

Canon 17-40mm f/4L

The 17-40 is a stop slower than the 16-35, but otherwise there’s very little difference between them. Some reviewers have found the 17-40 is actually sharper at the wide end and it may be less prone to lens flare. Its an excellent quality wide angle lens at a very reasonable price.

Roger’s Take: Like the 70-200 f/4, this is a reasonably priced “L” quality lens that is just excellent. I prefer it to the 16-35 f/2.8 for landscape and outdoor wide angle shots. Its every bit as sharp, perhaps sharper, and is more flare resistant. Plus it takes more reasonably priced 77mm filters. If you don’t need f/2.8, this is the wide angle lens of choice for full frame cameras in my opinion. On a crop frame camera, the 17-55 f/2.8 IS offers image quality nearly as good with added image stabilization. Its a bit more “fragile” than the 17-40, though.
