Lens Review
Introduction | Canon EF 17-40mm f/4L USM lens performance | Canon EF 17-40mm f/4L USM versus Canon EF 16-35mm f/2.8L II USM | Conclusion

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.
