DxOMark tested the Canon EF 17-40mm f/4L lens (price & specs), a well-known work-horse for lots of photographers, and one of the less expensive “L” lenses. More after the break.
Due to its more glamorous sibling this modest lens is often overlooked though it’s well known for its high-performance by Canon users. As a small, light, highly portable zoom it would make a great choice for travel, landscapes and general-purpose photography. Although not exactly cheap at $839, if portability is a concern it’s a great alternative to the faster model.
I was curious to see how the 17-40mm and 16-35mm performed on an EOS 70D, when compared to the awesome Sigma 18-35mm f/1.8 DC HSM (price & specs). See below, and judge by yourself.
The Sigma scores 27 points, compared to the 15 of the 16-35mm and 14 of the 17-40mm.
