Amazing piece of glass
"Pros:
? Cheapest L series lens on the market
? Reasonably fast (F4)
? Sharpest of Canon's Ultrawide Angle lenses (Q3, 2011)
? 77mm Diameter
? Distance/Focus gauge
? Excellent Build Quality
? Excellent Image Quality
Cons
? Not quite as wide as Nikons flagship 14-24mm
? Lose one stop of light vs the 16-35mm
? Corners are poor quality @ 17mm on Full Frame
? Aberration needs heavy correction.
Overall this is a fantastic lens, and if you don't find yourself needing a wide angle full time, but still want that focal range, this one for sure. It is SHARPER than the 16-35, however if you are using a wide angle often, look into a F to EF adapter and get the Nikon 14-24. Best wide angle on the market."

To Josh
"I would disagree with Josh. You can't compare 17-40mm lens to 14-24mm lens and rate them. You are comparing apples and oranges.
17-40mm L is a great glass for its value."

Great glass for a great price.
"The 17-40 f4L is my first L series lens and I've been more than happy with it's performance over the past month (shooting with 60D). For the money you're getting a great focal range making this a very versatile lens. I've found applications for it in everything from landscape to street. With it's wider end being 17 I'd probably avoid portrait because of the distortion but that's to be expected I think from this type of lens. Considering the highest f-stop is 4.0 the bokeh is pretty reasonable. Vignetting is noticeable when at it's widest but disappears when brought in to 40mm. The build quality is amazing as well and the focus, and zoom rings are really smooth. This being my first I thought it was a big deal! Also if you add a filter it is water sealed assuming your body is as well.
TL DR Amazingly versatile and strong piece of glass for the price. A great introduction to the L series."

L Lens at an Affordable Price
"The 17-40mm L is an amazing piece of glass. I use this lens on my 7D so I don't get the full capability of its width on the cropped sensor, which one would on full frame. But even mounted on a crop, it still gives a very wide field of view. The build quality of this lens is exactly what you'd expect of an L series. It feels strong, and has a good weight to it. There isn't any play in the rings, and it has a metal mount. And of course, it has that nice red ring. This lens produce fantastic image quality. With a max aperture of f/4.0, you aren't going to get shallow DOF but that isn't really the purpose of this lens anyway. Between f/8 and f/11 is where is lens shines with amazing sharpness, edge to edge. An indication of what this lens is intended for landscape photography. I can't say enough about how good this lens is. A lens with this level of quality, and the L moniker at such a good price you can't go wrong. If you enjoy landscape photography this lens will not disappoint."

Great Camera for Holiday-makers
"For its price, the Nikon Coolpix P7000 provides a newbie like me the ability to take slightly more interesting shots given its array of feature sets available - a step higher than your standard lower end compact digital cameras. I was seriously considering a DSLR camera but knowing myself, and that I dislike lugging around a large camera everywhere I go when I am on vacation, I decided why not stick with a camera with the same design frame (compact like) but provides great features for photo taking. Furthermore, I saved half the cost and at the same time enjoyed the benefits of shooting higher quality shots that Nikon p7000 has to offer me. Unlike your standard $100-$200 compact cameras, this model has a more solid and sturdy frame and has a very good grip. I also like the fact that it comes with sleek looking neck strap that allows me to rest the camera on my shoulder or around my neck in the even that I am not taking any shots. This camera also comes with a view finder which is a plus for me since I sometimes prefer the ol-fashion way of taking shots. One thing is for sure is that unlike my old compact camera, the Nikon P7000 was able to take better night shots while at the same time has a longer lasting battery life. Overall, I would recommend this camera for those who are not so sure of going for a DSLR but at the same time want to benefit from a camera that allows you to do more with what you can take."

Q & A
I have & love this lens, but I'm wondering why you chose not to put image stabilization on it?
Simon, sorry for the confusion. I thought I was posing (posting?) the question to Canon. Your answer makes total sense. Thank-you. George
