For those buying a brand new Canon DSLR I would certainly recommend this over the standard kit lens. Faster glass is always worth the extra investment.

I bought this lens in October of 2013 for my T2i and I love it. It's the only lens I have for my camera but I think it's worth the upgrade from the kit lens that comes with the T2i. Great all-round general purpose lens.

Well-built, wide-aperture, APS-C zoom with three-stop image stabilisation

Peak resolution

Some colour fringing

This lens is the same as the kit lenses that come with the rebel series. ONLY A LOT BETTER! first off the F/2.8 is great in all situations especially for wonderful bokah and low light situations. The only reason why this lens is not an L series is because it does not work with all the cameras.

Consistent Output; Easily Interchangeable; Fast; Rugged; Sharp Focus

Amazing image stabilisation that didnt work on a 550D but worked PERFECTLY on a 7D - easily best lens for EF-S - don't hesitate, just get one! Slightly too heavy, but will have to get used with it...

Great lens, takes sharp pictures, great low light quality. Kind of expensive, but cheaper than L class. Heavy, but good heavy(glass).

Consistent Output; Easily Interchangeable; Fast / accurate auto-focus; Nice Bokeh

Expensive; Heavy

The Canon EF-S 17-55mm f/2.8 IS USM is the fastest standard zoom dedicated to Canon's APS-C DSLRs, and is designed to be an upgrade for disgruntled kit lens owners who want better image quality.

Very Sharp and Fast focus lens, crop sensor L quality and was bid 16-35L lens!

Best lens for canon apsc DSLR. Great image quality and static aspeture f/2.8 makes low light shooting easy.
