Canon EF-S 17-55mm f/2.8 IS USM Lens
To meet user demands for a fast EF-S zoom lens, Canon has specially designed a new lens with a large aperture of f/2.8 for select Canon Digital SLR cameras.* The large circular aperture produces a shallow depth-of-field, creating background blur that draws attention to the photographic subject. The lens construction includes UD and aspherical elements, which deliver impressive image quality throughout the entire zoom range. Image Stabilizer lens groups shift to compensate for camera movement so that the image appears steady on the image plane, ensuring clear, crisp images, even in dim light. With a Ring-type USM, inner focusing and new AF algorithms, this lens achieves autofocus quickly and quietly, and with full-time mechanical manual focusing, manually adjusting the focus is possible even in AF mode.Product Review
An EF-S lens. $1,000. I told myself repeatedly that I would not buy it. I mean come on, a non-L series lens for this much money? You have got to be kidding me? After killing myself over the decision between the Canon EF 24-105mm F4L IS USM and the Canon EF 24-70mm F2.8L USM lenses, I somehow ended..Like so many people, I bought this to replace my kit lens. In my case that's the 18-55mm IS associated with the XSI. The main issue I had with that lens was the variable (and small) aperature. I wanted constant 2.8 without sacrificing zoom or IS. That's what you get here.
I purchased the Canon EF-S 17-55mm f/2.8 IS USM Lens primarily for my wedding photography business. This lens has proven to be more valuable to me than I ever could have imagined.
