Wide Angle Lens For Canon Eos Camera

Sandra asks…Need lens recommendation for my camera.?I recently bought a Canon EOS 40D and I am looking for a good wide angle lens. I have two lenses: Canon 24-105mm f/4 L for general purpose photography and Canon 50mm f/1.2 L for portraits. Does anyone know of a good wide angle lens for my camera given its 1.6x crop factor and my existing lenses? Is 17-40mm f/4L a good wide angle on a 1.6x cropped sensor?mr.eos answers:For the 40D (and other cameras with the EF-S mount), Canon makes an EF-S
