Breaking Canon’s claimed resistance to designing ’superzooms’, the EF-S 18-200mm f/3.5-5.6 IS is designed exclusively for use with EOS cameras featuring an EF-S lens mount – including the new EOS 50D, EOS 1000D, EOS 450D, and earlier models. (The cosmetic design with the silver rings is unusual in a lens costing this much; it’s reminiscent of lower-cost Canon lenses, and an all-black design might have been better received. - Ed)
The EF-S 18-200mm f/3.5-5.6 IS features a 16 element, 12 group construction. This includes UD and aspherical lens elements, which minimise chromatic aberration and ensure crisp, corner-to-corner detail across the zoom range. A close focusing distance of just 45cm offers photographers total framing flexibility.
A Canon 4-stop optical Image Stabilizer – specially designed for the lens’ specific focal length range - works to counteract image blur that can occur when shooting handheld, or at slow shutter speeds. Automatic panning detection ensures effective performance when tracking moving subjects. Plus, because the IS system is based in the lens, results are visible through the viewfinder during framing.
Reflection off a digital camera’s image sensor can cause flare and ghosting. To suppress this, the EF-S 18-200mm f/3.5-5.6 IS uses optics treated with Canon’s patented Super Spectra coatings – for crisp, undistorted images with natural colour balance.
