Canon EF 70-200mm f/2.8L IS USM III Lens

New EF 70-200mm f/2.8 Mk III Lens

One of the most versatile lenses available, the Canon EF 70-200mm f/2.8L IS III USM is an 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. zoom distinguished by its bright design and advanced optics. Ideal for a variety of subjects ranging from portraiture to sports, the fast constant f/2.8 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. excels in difficult lighting conditions and also offers increased control over depth of field for isolating subjects.

The optical layout makes use of one fluorite element and five UD elements to suppress chromatic aberrations and colour fringing in order to realise a high degree of clarity throughout the zoom range. An Air Sphere Coating is also featured and works to reduce 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. and ghosting for greater colour fidelity and 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). in all conditions.

Complementing the speed and optics is an Optical Image Stabiliser, which compensates for 3.5 stops of camera shake to better enable working handheld and in low-light situations. A ring-type USM and internal focusing mechanism also afford quick, quiet, and accurate autofocus performance, as well as full-time manual focus override. Additionally, this lens is weather-sealed for use in trying environmental conditions.
