Conclusion: I have carried this lens for little over a year now, using it mainly for real estate photography and landscapes. For this purpose, there was no need to opt for the 16-35 f/2.8, which is double the price. The lens is also great for party shots, when you need to get a big group in the picture. Although there is some distortion, thats what you get at 17mm, with any lens. Between the weight, price, build, and sharpness, this is one of the best "L" lenses that Canon makes.
Conclusion: This lens is sharp from front to back and is one of the sharpest in its class, its the only super wide I have used for years and still is my go to lens for the shot. The quality is well build and weather sealed. It never looked faded or used, flare is under controlled F4 is very sharp and can be used as a macro lens as well, great for portraits. You will not be disappointed with this lens.
Summary: The 17-40 gets mixed reviews for the most part mainly due to poor corner and edge resolution wide open. I use this on the 5D Mark III, a full frame sensor that will show these soft edges much more than a crop sensor such as any rebel, 7D, 60D, etc... Even then, I find the edge performance really quite good once you stop the lens down. Central sharpness is very, very good at 17mm and 40mm wide open.
A perfectly satisfactory ultrawide zoom lens, but not the top such lens Canon makes

Summary: Most photographers who consider themselves serious amateurs and probably almost all professionals will have at least occasional need for an ultrawide lens. Interiors, architectural exteriors, and some travel scenes are best recorded by a lens whose angle of acceptance approaches or exceeds 100 degrees.
Summary: Great for landscapes, sunrises, and sunsets - particularly in combination with graduated neutral density filters to balance exposure of land and sky. Amazing for indoor room photos - a must for any Realtor. Superior for architects' pictures of structures. Fine opportunities for creative "street photos" with artistic approaches and unique angles.
Pros: Easily Interchangeable, Fast / accurate auto-focus, Lightweight
Conclusion: This is a great affordable L series lens. It is wide enough for a full frame or crop body. It is built like a tank and a very reliable lense @ f/4. No need for 2.8 if you use a flash or light your subject correctly.
Pros: Fast auto-focus, Superior build quality, Super-sharp images
Great nature lens, but has also shown itself useful in other situations

Summary: I bought this lens shortly after buying the 24-105 f/4L and seeing the difference all-around in pro glass. While portrait photography is my main thing, I wanted something else that I could bring on hikes and walks to capture some local views, especially during the fall. A lot of times, when we get back home, the colors we caught don't look like the ones we remembered seeing in our head, and I have had that happen a lot less often with this lens.
