The EF 20mm f/2.8 USM Lens from Canon is an ultra-wide-angle lensWIDE-ANGLE LENSHas a short focal length, hence a field covering a wide angle, ideal for architectural, interior and landscape photography where the photographer may be unable to move further away from the scene to photograph it. Wide-angle lenses come in both fixed-focal length and zoom lens varieties. with a fast 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. for full frame EF mount cameras. 


Precise, fast and quiet autofocus

A floating rear focusing system gives sharp images at all subject distances and an ultrasonic motor (USM) enables fast, smooth and quiet autofocus. Full-time manual focus override allows for precise manual focus even when in AF mode. The minimum focus distance is 9.8". 


Suppress 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.

Sharp, high-contrastCONTRASTThe difference between areas of different brightness levels in a photograph: A high-contrast image has a greater difference between light and dark areas, whereas a low-contrast image has a narrow range of tones. Contrast is used to direct a viewer’s attention to a photographer’s subject either with colour contrast (bold versus duller colours) or tonal contrast (bright versus darker tones). images and minimised aberrations result from the lens' optical construction which includes aspherical and Super UD lens elements.


Superior protection

Canon's Super Spectra lens coating suppresses ghosting and flare by absorbing light that might otherwise reflect off the camera's sensor. A metal front barrel (including filter ring and lens hood mount) provides durability and a stable hold for those optional accessories.
