Digital camera reviews of Canon EF 17-40mm f/4L USM Ultra Wide Angle Zoom Lens for Canon SLR Cameras
Digital camera Review: It's really nice, but...
Summary: 4 Stars
this lens is my first L, and i was hoping to be blown away. perhaps that was my own mistake for setting my expectations too high. don't get me wrong, it's a great lens, and it does everything i need it to do very well, but i could have gotten a lens for $300 cheaper that would do the same at about the same quality. one thing i do really like is the ultra fast, ultra quiet auto focus. the design is very sturdy, and it does take some great shots. honestly, though, i keep returning to my <$100 50mm to do the serious shooting.
