Product Description
Can Ef S 17 55mm F28 Is Usm Lens , Pelican 1750 Case , Can 200dg Digital Camera Gadget Bag , Epro Slingshot 102 Aw , Case Logic Tbc 307 Slr Camera Backpack , Product Description Designed to meet consumer demands for a fast EF-S zoom lens, the EF-S 17-55mm offers image quality on par with Canon's highly regarded L-series lenses. The lens features a large circular aperture that produces a shallow depth of field, creating background blur that draws special attention to the photographic subject. The lens construction, meanwhile, includes UD and aspherical elements that deliver impressive image quality throughout the entire zoom range. And thanks to the Image Stabilizer lens groups--which shift to compensate for camera shake--the image appears crisp and clear on the image plane, eve in dim light. Finally, the lens offers a ring-type ultra-sonic monitor (USM), inner focusing, and new AF algorithms to help achieve autofocus quickly and quietly, along with full-time mechanical manual focusing that makes it possible to manually adjust the focus even in AF mode. As with all Canon lenses, this lens carries a one-year warranty.

This review is from: Canon EF-S 17-55mm f/2.8 IS USM Lens for Canon DSLR Cameras (Camera)
This is an amazing lens. I used it for 1000+ pictures on a recent trip to Egypt. It never came off my 20d. The low light performance is stellar as is the sharpness. The weight of the lens has been described as a detracting factor but I found it nicely balanced. The build quality has also been questioned by some but other than a significant problem with dust intrustion, this is built well (not like a tank mind you, but well).
Now for the negatives: this lens does suck in dust. I went to Egypt with one little teeny fleck of dust (provided by Canon...). To be fair I used it in some of the dustiest conditions I have experienced (I needed to wipe the lens barrel several times to get rid of talcum like dust in Luxor) and it came back with many.many more flecks inside.
Thus my recently purchased 17 55 looks like an aged lens that has been thru the wringer.
These flecks have not affected image quality so far but do affect customer perception (remember photography is also about "gear" ;-). I think Canon does need to address this topic aggressively, if only as a cosmetic issue. One pays Canon $1000+ for this kind of lens to get customer service after all. If I were Canon, I'd issue a recall and get this sorted out via a proper dust seal and cleaning to maintain my leading brand image.
The only other small beef I have have is also directed at Canon: they need to stop doing silly things like charging $50 for the hood and "pretending" that L series are only for full frame lenses. There are going to be tons of 1.6x cameras out there, Canon needs to wake up and admit that they need 1.6x L grade lenses. I can imagine that some MBA told them that they could maintain "price differentiation" and "value addition" by their decision to keep L targeted only at full frame but this is a very myopic strategy.
I was and still am a Canon fan. With this lens, they have come close to sweet perfection but too bad that they let a dust seal steal away a perfect 10 score :-( The dust problem is real, please be aware of that as you consider this otherwise excellent lens.
