It's just does not have the 'hoopla' of lenses like the 70-200mm, but as good as that is for telephoto, this is superb for wide angle.
For the price.
Yes, you can get faster lenses, but on a full frame this a as wide as you will need for just about anything,
on a crop sensor you want to buy the Canon 10mm-22mm EF-S lens.
This is good on a crop camera, and will work, on one, just wont be as wide.
No Image Stabilization is OK. Wide angle lenses are much more forgiving with handheld shots in bright light,
and in dark, you just get a good tripod, which every photographer should already have.
This lens rules. Sharp images, corner to corner.
To me, this really is a full-frame lens where you can really utilize that great 17mm perspective. I think there are better options for those shooting with the 1.6x APS-C sensors. But that really is really up to the users and the needs they have. My girlfriend often borrows this lens to use with her T2i and loves it (I think the images look fantastic, as well!).
One thing I love most about this lens is the contrast and color rendition. Simply beautiful images straight out of camera. The build quality is top notch as well, the zoom and focus rings are very smooth and well damped. The lens is weather sealed, but does require a filter (per-Canon) to complete the sealing.
I give this lens 5/5 stars, simply due to its extremely affordable price (for an L lens) and excellent performance. Sure, there are sharper lenses out there, but that does not hinder this one at all. It still performs great and is a blast to use for dramatic perspectives. One of the most fun lenses to mount to the camera IMO. The light weight, great build quality and very good IQ make this a winner and a spot in my collection.
Its advantages include its utility as an all-purpose wide angle lens (capture range from slightly wide to ultrawide) and its relatively low price for a complicated semi-specialty lens. At f/4 it is not a fast lens, and as has been pointed out in other reviews it suffers from slight softness at some apertures. It is one of Canon's L (red ring) lenses, which are higher-end products, and one can trust the company to have minimized the negative issues that can emerge in complex lens designs. If you feel the need for a perfectly satisfactory wide-angle zoom or primary lens, but don't want to break the bank to get the best one, this is a good lens to consider.
On the other hand, if you want a faster lens with a bit more lateral grasp, Canon also offers the 16-35mm f/2.8 zoom lens (also in the red ring/L class) at about twice the price of this one. The more expensive lens offers not only what the 17-40mm zoom does (though it does not go quite as close to a normal focal length on the high end), but provides in addition extra light capture for lower-light environments and the slightly wider angle of acceptance. If I had thought a little longer about the differences between the two lenses, I would have ordered the more expensive one. I may upgrade at some point in the future if I ever feel constrained in the use of the one I did buy. But I am not dissatisfied with this lens and have no qualms giving it the five-star rating it deserves in its own right. It is a solid and reliable tool, well made, and provides excellent images.
