Increase Your Lens's Focal LengthFOCAL LENGTHMeasured in mm, it is the distance from the focal point of a lens (its centre or curved mirror where light converges) to the plane of the image sensor (film) when an object is in focus. A shorter focal length lens sees a wider image and a longer focal length brings your subject closer. For example, a 15mm lens sees a very wide image and is perfect for landscape photography. Conversely, a 500mm lens sees a very narrow image, brings the subject much closer and is thus great for subjects that are far away, like a bird in a tree. With zoom lenses, its minimum and maximum focal lengths are indicated, for example, as 24-105mm. A zoom lens allows you to change the lens’ focal length, with shorter (wide-angle) and longer (telephoto) options, whereas a fixed focal length lens requires you to move back and forth to find the correct image composition. by A Factor of 2X

The Extender EF 2X III from Canon is designed for select Canon EF mount L-series telephotoTELEPHOTOA lens with long focal length capable of making distant objects appear nearer thus larger. Essentially, it isolates and magnifies the subject so that it appears as a full image when shooting from a distance. Telephoto lenses are ideal for photographing subjects that are further away, such as wildlife and sports photography. lenses. It 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 combines redesigned optics, improved data communication between lens and camera and enhanced environmental protection. It is ideal for photojournalists and wildlife, nature and sports photographers who need to get close to distant and challenging subjects and it reduces the need to carry heavy telephoto lenses.


Improved optical performance

The Extender EF 2x III features nine optical elements in five groups, ensuring improved optical performance. All optical elements have Canon's Super Spectra coating to reduce ghosting and flareFLAREOccurs when a point light source such as the sun or an artificial light (that is brighter than the rest of the scene), hits the front element of a lens resulting in a lack of contrast, haze, or unwanted semi-transparent objects being present in the image. You can avoid lens flare with a lenshood or filters, however, the effect is also useful for bringing artistic elements into an image, such as sun rays peaking out from behind a rock formation. . 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.

To facilitate the accurate transfer of imaging data between the lens and camera body, the extender features an integrated processor which ensures all focusing, metering and ID information is available - allowing the photographer to capture balanced, well-exposed images. When combined with the latest range of premium Canon L-series lenses, these extenders enable AF accuracy even when capturing moving subjects. When attached, the 2x extender reduces the effective maximum apertureAPERTUREAperture, shutter speed and ISO form what is known as the exposure triangle in photography. Aperture refers to an opening inside the lens, similar to the iris of your eye, that changes in diameter to control the amount of light that enters a camera. Aperture is expressed in f-stops: the lower the number, the larger the aperture, e.g. f/1.4 is larger than f/8. A larger (or wider) aperture allows more light to pass through the lens to the sensor (film) as a picture is taken, particularly useful in low-light conditions. A larger aperture also produces a shallower depth-of-field, and thus more background blur. by two stops.


Exceptionally build-quality

A carefully positioned lens release mechanism also makes it easy to mount the extenders quickly, reducing the time that the camera and lens are exposed to the environment. The extenders offer the exceptional build-quality expected from Canon's professional products, and are resistant to both dust and water, allowing photographers to use them in extreme shooting conditions.
