Product Description
It can be used with wide variety of subjects and it is an ideal large aperture standard zoom lens for digital SLR cameras featuring APS-C size image sensor.This lens has a minimum focusing distance of 7.9" (20cm) throughout the entire zoom range. Maximum magnification of 1:2.3 enables close-up photography like a macro lens. This lens design and multi layer lens coating reduce flare and ghosting, which is a common problem with digital cameras. A Special Low Dispersion (SLD) lens and two aspherical lens elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range.This lens offers a large aperture of F2.8 at 17mm wide angle and yet it is compact, with an overall length of 82.5mm (3.2") and diameter 79mm (3.1"). It performs superbly even in relatively low light conditions indoors or at dusk.The lens design incorporates an inner focusing system, which ensures fast AF speed as well as prevents the front of the lens rotating, making it particularly suitable for use with circular polarizing filters and petal shaped lens hoods. This lens is also equipped with Zoom Lock Switch that eliminates 'Zoom Creep' during transportation.

 Great all around lens August 16, 2008
Melinda Tuttle (Coastal Washington State)
I have found this to be a great all around lens. The pros of this lens are that it does a really great job focusing and has very sharp pictures in most situations. It is very fast. I have captured bees in flight and have been amazed with the clarity. The color is spot on. I am used to having to adjust the color/saturation in photoshop after uploading photos. I rarely have to do so with this lens. I also love that you can get very close to the subject and still focus. Makes macro type work very enjoyable. This isn't a true macro lens but it does a very nice job as "almost macro".
The cons are: this is a heavy lens. I would not want to carry this around my neck all day long. That is a pretty minor con..definitely wouldn't deter from buying. It also does poor in low light. I had to shoot a wedding after sunset and this lens was very soft (focus) in such conditions.
It can be soft (focus) at the end (70mm) also.
I would highly recommend this lens if you want to replace the kit and have a great lens that rarely leaves the camera.
Great "Walkaround" Lens at a great price! August 12, 2008

I was looking for a good every day lens that I could take with me on a trip to San Francisco this past summer but being just a light hobbyist, I didn't want to spend the money for the high cost of some of the canon lenses like the 17-40L or the 17-55IS. So after reading alot of the helpful reviews here, I decided I would give this lens a shot and I'm very happy that I did.
The image quality on this lens is far better than the kit lens that came with my Canon XTI 400D. It actually feels like a whole different camera now. Pictures are sharp and the contrast and color the lens produces are head and shoulders above the kit lens. Also the extra reach this lens has over the kit lens comes in handy too.
At 17mm, the f/2.8 really works well indoors in lowlight situations, but it does stop down quickly...at 20mm, it already jumps to f3.5 and quickly goes up from there. The lens focuses fast and not as loud as I'd expected(going off of some other reviews) and the build quality is good also.
Some extra bonuses that I was happy about...
The Macro feature is a definite bonus, I can zoom into an object that's right up against the lens and it'll still focus well. The lens even came with a hood as opposed to having to buy a separate lens hood($45)for a canon lens.
A few things that were on the negative side...
The lens does tend to hunt in very low-light situations and there is some barrel distortion when shooting wide. Also it's much larger than the kit lens but you do get ALOT more lens so the trade off in weight is well worth it. Plus, I have a battery grip on my XTI which nicely balances it out.
Overall, the pros for this lens far outweigh any cons that this lens might have. It's nearly half the cost of the 17-40L f/4, and almost a third of the cost of the 17-55IS f/2.8. For someone that mainly shoots as a fun hobby on weekends, this was the perfect lens to fit my needs.
Great addition to my collection June 9, 2008

I am a photographer on a budget, not a pro, not a novice, I fall somewhere in between. Maybe it's an obsession for me, an expensive hobby to be sure therefore I like to save money where I can, when I can. This lens aligned well with my collection, I have an 18-55mm (kit), 28-135mm (kit), 50mm f/1.8, 100mm f/2.8, and 70-300mm f/4-5.6. I bought this because the 18-55 just isn't up to par. The 28-135 is much better than the 18-55 but doesn't have the wide angle. This lens for $375 fills that wide angle and fills the gap to my 70-300mm perfectly. Overall I'm very impressed with this lens; I just spent a week in NYC taking photos and used this lens almost exclusively. I am very impressed the with the quality, is it L quality, no, did I pay for L quality, no.
By the way, I now have an 18-55mm and a 28-135mm for sale now if anyone is looking for one.
