Top-Level Performance Optimised for the Era of Ultra-High-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. Cameras

The Sigma 24-70mm f/2.8 DG HSM OS Art is a premium workhorse 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. designed for the latest high-megapixel DSLRs. A 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. of f/2.8 through the zoom range make this a highly versatile tool and a brand new Optical Stabilisation (OS) system help compensate for camera shake. Though a common 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. , the Sigma 24-70mm Art brings a new level of usability and durability featuring a rugged metal barrel and an emphasis on image quality. Building off the experience from the 12-24mm Art, the aspherical elements used in the 24-70mm f/2.8 OS Art undergo a highly precise level of polishing producing elements thicker in the centre than on the edges. This process creates stunning image quality and beautiful circular 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.. Like each and every Global Vision Lens, the Sigma 24-70mm f/2.8 DG HSM OS Art is handcrafted at our single factory in Aizu, Japan and undergoes individual evaluation before leaving Sigma’s facility.


Landscapes to Portraits, All with Exceptional Optical Quality

Three SLD (Special Low Dispersion) glass lens elements and four aspherical lens elements help minimise optical aberrations. To ensure outstanding image quality from the centre to the edges of the photograph, the optical system minimises coma, which causes points of light to streak, and transverse chromatic aberration, which cannot be corrected via aperture control, The optical system also minimises distortion, which can be particularly evident in wide-angle shots, resulting in excellent optical performance throughout the zoom range.


Capture Beautiful Portrait Photographs with a Bokeh that is a Cut Above

At wide-open aperture, this lens offers outstanding photographic expression. The area in focus is extremely sharp, while the background exhibits a beautiful bokeh effect with only slight spherical aberration. Since large-diameter zoom lenses are often used at wide-open aperture, SIGMA has paid close attention to the shape of the bokeh, aiming for perfect circularity. 


OS Functionality and Newly Designed HSM for Success on any Shoot

Designed for advanced utility in a wide variety of situations, the optical stabiliser (OS) offers a powerful stabilisation effect. The newly designed large hypersonic motor (HSM) offers 1.3 times the torque of its predecessor and exceptionally stable performance even at lower speeds.


Lens Barrel Designed for high Rigidity

Since large-diameter standard zoom lenses tend to serve as a go-to lens and see frequent use, the SIGMA 24-70mm f/2.8 DG HSM | Art is designed to stand up to the challenging shooting environments that pros encounter. To this end, the lens barrel contains a large amount of metal, while the external moving parts feature thermally stable composite (TSC), which is resistant to thermal expansion and contraction. This structure contributes not only to the outstanding optical performance of the lens but also to its high rigidity and confidence-inspiring build quality.


Shoot in any Weather with a Dust- & Splash-proof Mount Design

Since the area of the lens most vulnerable to dust and other foreign bodies is the mount, rubber sealing helps provide peace of mind. In addition, the front lens element features a water- and oil-repellent coating that helps the lens perform well in the rain, near water, and in other challenging conditions.
