The EF 16-35mm f/2.8L III USM is an indispensable ultra wide-angle zoom lensZOOM LENSAllows a camera to, unlike a fixed-focal length or prime lens, change smoothly from a long shot to a close-up or vice versa by varying the focal length. A true zoom lens, also called a parfocal lens, is one that maintains focus when its focal length changes. Due to more moving parts, zoom lenses often produce images of slightly lesser quality than their prime lens counterparts. However due to the inherent flexibility of being able to vary the focal length, they are extremely popular for photography where composition needs to be adapted quickly - such as at weddings, for example. for professional and enthusiast photographers who demand superlative operation and performance, in virtually any condition. Its 16-35mm focal range provides superb control of perspective, helping you capture pictures and movies with amazing, dramatic compositions limited only by your imagination. Combining outstanding image quality, a fast, constant 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. and a rugged design, the EF 16-35mm f/2.8L III USM delivers eye-catching results whether capturing detailed, nuanced landscapes, dramatic interiors and much more. Both still and moving images can be captured with consistent edge-to-edge sharpness, improved peripheral illumination and reduced distortion at extremely wide angles - especially important when using SLR cameras with full-frame sensors. Engineered with high-resolution photography and videography in mind, the EF 16-35mm f/2.8L III USM provides the optical performance necessary for critical applications, while delivering the renowned function and feel you've come to expect from Canon's celebrated L-series lenses.
Large F/2.8 Constant Aperture Provides Superb Control Over ExposureEXPOSUREExposure is controlled by three elements: Aperture, Shutter Speed and ISO. Achieving the correct exposure is similar to collecting rain in a bucket, up to an optimum level. The rate of rainfall is out of your control (light), yet you can control these three factors: the bucket’s width (lens aperture), the duration you leave it in the rain (shutter speed), and how effective your bucket is in collecting rain (ISO). These three elements work together to control the amount of light per unit area, preventing underexposure (too dark) or overexposure (too bright), giving you a natural looking image. and Depth-Of-Field
The EF 16–35mm f/2.8L III USM has a bright constant maximum aperture of f/2.8, which provides superb control over depth-of-field and the ability to maintain the same aperture throughout the zoom range. This is particularly helpful when shooting outdoors at dusk or in inclement weather, or indoors in dimly lit rooms. At f/2.8, the EF 16–35mm f/2.8L III USM offers a bright view when composing images using the camera’s viewfinder.
All-new Optical Design for Significant Improvements in Outer Corner Sharpness
The EF 16–35mm f/2.8L III USM features a new optical design engineered to deliver images of remarkable clarity and depth – a magnificent complement to the large, high-resolution sensors in the SLRs favoured by today’s advanced photographers. It employs two large-diameter double-surface GMo lenses plus a ground aspherical lens to help decrease distortion, curvature of field and astigmatism. Two UD lenses help to reduce chromatic aberration, leading to precise color rendition, accurate edge-to-edge detail plus excellent 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). throughout the lens’s zoom range. This means sharp landscapes, reduced distortion in the edges of the frame and an overall improvement in image quality no matter the subject.
Sub-wavelength Coating (SWC) and Air Sphere Coating (ASC) Significantly 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
The EF 16–35mm f/2.8L III USM features both Sub-wavelength Coatings (SWC) and Air Sphere Coatings (ASC) on its lens elements to help combat reflections, flare and ghosting, and deliver clean images with reduced aberrations from reflected light. Sub-wavelength Coatings help prevent reflections by arranging an array of wedge-shaped nanostructures on the lens’s surface that are smaller than the wavelength of visible light and are able to help control reflection and flare. Air Sphere Coating technology puts an ultra-low refractive layer on the lens element designed to significantly reduce both flare and ghosting. These coatings, in concert with the EF 16–35mm f/2.8L III USM’s overall optical formula, help to deliver a clean image to the camera’s sensor, which can decrease the need for post-production.
Circular 9-Blade Aperture Helps Deliver Beautiful BokehBOKEHPronounced: /ˈboʊkɛ/, /ˈboʊkeɪ/ [boh-kay] or /ˈboʊkə/ [boh-kə]
Originating from the Japanese word Boke (ボケ), meaning 'blur' or 'haze', it refers to the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. It has also been defined as the way the lens renders out-of-focus points of light. Bokeh depends on various aspects of lens design. Aperture design has the largest effect on Bokeh, and generally a lens with a more rounded aperture produces a more pleasing, natural Bokeh.
Thanks to its 9-blade, circular aperture, the EF 16–35mm f/2.8L III USM is capable of gorgeous, evocative out-of-focus areas and soft backgrounds throughout its zoom range. Its f/2.8 maximum aperture enables shallow depth-of-field, which is often difficult to achieve with 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.es and lenses with small maximum apertures. By delivering an incredible level of control over background blur, the EF 16–35mm f/2.8L III USM helps you define the mood of your image, creating impactful photos and videos.
Fluorine Coating Helps Reduce Fingerprints and Fingerprints
To help maintain a clean lens, even after multiple lens changes in sub-optimal conditions, the EF 16–35mm f/2.8L III USM has a specially designed non-stick fluorine coating on its front and rear surfaces. This fluorine coating helps prevent dust, water, oil and other surface residue like fingerprints from sticking to the lens, resulting in quick and easy wiping, without the use of solvents.
