EISA AWARD WINNER FOR BEST DSLR ZOOM LENS 2018-2019

The Sigma 14-24mm ART Series wide-angle zoom lens is the perfect tool for serious landscape and architectural photography. It offers an extremely wide angle of view with minimal distortion and excellent control over destructive chromatic aberration so often experienced with wide-angle lenses. An ultra-fast f/2.8 aperture allows for the use of faster shutter speeds in low light conditions and renders crisper images, free of blur when shooting hand-held in darker than ideal conditions. The 14-24mm ART is compatible with the Sigma USB dock which enables fine focus adjustment.

Outstanding Art line image quality

Designed to team up with 50-megapixelPIXELThe shortening of 'picture element', a basic unit of programmable colour forming the dots that make up an image. Pixel size depends on a camera’s resolution, which is measured in megapixels (MP), meaning millions of pixels. The more pixels on a sensor, the smaller they have to be to fit. An image's number (or density) of pixels correlate to the amount of information and image holds. Cameras with more pixels on the sensor have a higher pixel density and thus more resolving power, able to capture smaller details with much more clarity and accuracy. Higher resolution images can be cropped more agressively and also produce better quality large prints.-plus cameras and offer top-level optical performance throughout the zoom range, the 14-24mm f/2.8 DG HSM | Art incorporates three FLD glass elements, three SLD glass elements, and three aspherical lens elements, including one large-diameter aspherical element. Effective distribution of these high-refractive-index glass elements further enhances the corrective effect of the FLD and SLD glass. This optical system minimises transverse chromatic aberration and other optical aberrations, resulting in outstanding high-resolution image quality.
The first element in the optical system is a large-diameter aspherical lens. Optimising the power distribution of this and the other lens elements minimises distortion to 1% or lower. As a result, points of light appear as points without streaking from the centre of the image to the edge, and the light volume is also abundant throughout the frame. In addition, simulations performed from the design stage onward have helped minimise 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. In combination, these technologies ensure excellent ultra-wide-angle performance.

The definitive wide-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. 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.

Leveraging major manufacturing advances at the Aizu factory, Sigma is now producing ultra-high-precision moulded glass aspherical lens elements as large as φ80mm and incorporating them in new products. This premier optical technology promises to set a new standard for excellence in 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.
For the Art line, Sigma began development simultaneously of two ultra-wide-angle lenses offering the key 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. of 14mm: one prime, and one zoom. In 2017, the company launched the 14mm f/1.8 DG HSM | Art as the ultimate ultra-wide-angle prime lensPRIME LENSA photographic lens used as an (1) alternative, fixed focal length alternative to a zoom lens or, (2) more traditionally, as the primary lens in a combination lens system. In the first sense, a prime lens is known for having a larger maximum aperture and consequently offers greater shutter speeds, having advanced optics and weighing less than zoom lenses, albeit less flexible, because of their simpler construction with less moving parts. In the second sense, a prime lens refers to the primary lens when paired with other optical devices. A prime lens's focal length is fixed and the photographer is required to move closer or further to achieve the correct image composition.. This lens offers outstanding image quality in combination with f/1.8 brightness.
Now Sigma is introducing the 14-24mm f/2.8 DG HSM | Art as the ultimate ultra-wide-angle zoom. While minimizing distortion, this lens offers outstanding f/2.8 brightness throughout the zoom range and delivers top-level image quality at every focal length and every shooting distance. For these reasons, it is the definitive large-diameter ultra-wide-angle zoom lens.

Exclusive low-dispersion glass

The degree to which light is refracted by glass depends on the light's wavelength. This fact causes different colours of light to focus at slightly different points. The result is chromatic aberration, the colour fringing that is particularly noticeable in 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. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain. To minimise this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass and optimisation of power distribution gives SIGMA lenses superlative image rendition undiminished by residual chromatic aberration.

Designed to minimize flare and ghosting

From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and 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 even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.

Allowing photographers to work in all types of weather

Like SIGMA’s Sports line lenses, the 14-24mm f/2.8 DG HSM | Art features a highly effective dust- and splash-proof structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection, allowing photographers to work in all types of weather. In addition, the front of the lens is protected by a water- and oil-repellent coating that makes cleaning easy. The high-speed, high-accuracy autofocus helps photographers react in an instant to get those special shots.

Fast AF with full-time manual focus

Full-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring.

High-precision, rugged brass bayonet mount

The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

Rounded diaphragm

The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

Sigma USB Dock makes customization and flexible adjustment possible

With the optional SIGMA USB DOCK, you can update your lens firmware and adjust the focus position and other settings. Simply connect the lens to the SIGMA USB DOCK and the dock to a computer to use the dedicated SIGMA Optimisation Pro software and perform various types of customisation and adjustment.
