The Canon EF-S 55-250mm f/4-5.6 IS is a general-purpose telephoto zoom lens for photographers who want an affordable telephoto lens. With a focal length equivalent of 88-400mm in 35mm format, the lens is capable of most general telephoto photography. The aperture’s circular design is also ideal for isolating subjects at large aperture by delivering smooth and even-looking background blur.

In terms of image quality, the lens incorporates a 4-stop compensation Image Stabiliser technology that allows shooting at shutter speed of down to 4 times slower without image blur. It also has an UD (Ultra-low Dispersion) element and a Super Spectra Coating for accurate colour balance and high contrast and they suppress ghosting and flare by absorbing unwanted reflections in the lens. This lens is also environmental-friendly with lead-free glass being used.
