| A Superb Canon EF S 17 55 Mm F2 8 IS USM Lens - Presenting High Quality Image Sharpness, Fast & Exact Auto Focus
The Canon EF S 17 55mm f2 8 IS USM Lens is a tremendous, top quality lens that is basically made for the EF-S zoom lens range, though the image quality is so good that some have compared it to being on par with that of the renowned and highly regarded Canon L series range.
The main reason behind this is a large round aperture that creates a shallow depth of field and high quality low dispersion aspherical lens elements that make certain that you get excellent image quality throughout the entire zoom range.
This lens also has one more vital and equally as impressive feature - image stabilization. This means that the camera can accommodate for camera shake under certain circumstances, enabling you to shoot in low light more often and with more confidence that your images will still be of the best quality.
Furthermore, the EF S 17 55 f 2.8 IS USM features an easy to use, ring-type ultra-sonic motor and an extremely fast and user-friendly auto focus system, that is a true pleasure to use.
