"<p>The Canon Extender EF 2X III is designed for select Canon L-series telephoto lenses. The extender is perfect for photojournalists, nature and sports photographers who need to get close to distant and challenging subjects. The Extender EF 2x III increases the focal length of a lens by a factor of 2x while still delivering superb image quality. To ensure the best possible image quality in all shooting conditions, it also combines enhanced environmental protection, redesigned optics and improved data communication between lens and camera.</p>
<p>The extender allows professional photographers to shoot distant subjects without having to carry a number of heavy lenses. The Extender EF 2x III features five groups of nine elements, ensuring improved optical performance. All optical elements use Canon's Super Spectra coating, reducing ghosting and flare to minimize post-processing requirements. A new Fluorine Coating on the front and rear elements makes marks, such as spots left by water or fingerprints, much easier to clean than standard coatings.</p>"@en

"Designed for high-quality still image and video capture while being compact and lightweight, the EF-S 18-55 mm f/3.5-5.6 IS STM lens features the optics, AF and image stabilization necessary for shooting in any number of situations. For brilliant image quality it has one high-precision aspheric lens to reduce chromatic aberration throughout the zoom range. It features optimized lens coatings to ensure exceptional color balance while minimizing ghosting and flare and a 7-blade circular aperture to ensure beautiful, soft backgrounds. For outstanding performance, the EF-S 18-55 mm f/3.5-5.6 IS STM lens perfectly complements the movie servo AF feature found on select EOS cameras with a compact six-group zoom system and a stepping motor and focus mechanism to deliver smooth and quiet continuous AF during movie shooting. Still photography benefits from a high-speed CPU and an optimized AF algorithm. Full-time manual focus is available in AF mode and the front element does not rotate during focus, perfect for use with polarizing filters. Handheld photography is enhanced by the lens' optical image stabilizer system, offering the equivalent of four stops of compensation. Compact and highly versatile, it is the ideal lens to carry anywhere."
