Review on Canon EF 20-35mm f/3.5-4.5 USM Ultra Wide Angle Zoom Lens - Optimized for Canon SLR Cameras by Mirzet Gosselin

amazing wide angle lens for its price. Although this product has been discontinued by Canon, it still offers fantastic imaging capabilities and has been my favorite for landscape photography so far. its fast focusing and silent with USM. Manual focus correction is ideal for night shots. I don't notice any vignetting at the widest focal length, which is quite common with wide-angle lenses. there is also no barrel deformation. The construction seems solid enough to me with the metal bracket. It may take some time before I update this lens. A must for amateur photographers interested in landscape photography.
