Canon expands EF-S range with two new lenses

Amstelveen, The Netherlands, 20 August, 2007: Canon today strengthens its EF-S series of lenses with the launch of the EF-S 18-55mm f/3.5-5.6 IS and EF-S 55-250mm f/4-5.6 IS. With equivalent focal lengths of 29-88mm and 88-400mm respectively, the lenses are the first in the EF-S series to incorporate a 4-stop Image Stabilizer, dramatically extending low-light performance. Both lenses incorporate specialist optics to achieve exceptional image clarity - the EF-S 18-55mm f/3.5-5.6 IS employing an aspherical lens element with the EF-S 55-250mm f/4-5.6 IS benefiting from an Ultra-Low Dispersion (UD) lens element. The lenses are built to fit exclusively on those EOS cameras with an EF–S lens mount – including the new EOS 40D, EOS 30D, EOS 400D and earlier models.

The EF-S 18-55mm f/3.5-5.6 IS is a lightweight general-purpose zoom lens that is ideal for handheld photography in a wide range of lighting conditions. Offering high optical quality, the lens has an 11 element, 9 group construction, including one aspherical element for crisp corner-to-corner detail. The lens maintains a closest focusing distance of just 25cm throughout the zoom range, giving photographs the flexibility to frame up close when needed.

Compact and lightweight, the EF-S 55-250mm f/4-5.6 IS offers the longest zoom range in the EF-S series to date. The 88-400mm equivalent focal length opens up new framing possibilities for owners of EF-S mount cameras shooting wildlife, sports and travel photography. Optical quality is assured through a UD element, which minimises chromatic aberrations that could otherwise cause reduced contrast and colour fringing.
