Lightweight 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 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. with State-of-the-Art Technology
The Sigma 100-400mm 5-6.3 DG HSM OS Contemporary is a state-of-the-art telephoto zoom that brings a new level of portability and quality to the super telephoto market. Touting Sigma’s Optical Stabiliser (OS), the Sigma 100-400mm 5-6.3 Contemporary is highly compact and lightweight compared to similar products on this market. A push/pull zooming function and a new Hyper Sonic Motor (HSM) allow for a more responsive approach to photography while a 1:3.8 macroMACROProducing photographs that render extreme close-ups of extremely small subjects like insects, hence its popularity among nature photographers. It requires using a macro lens with a large reproduction (magnification) ratio of at least 1:1, which renders a subject larger than life size. Macro lenses are capable of focussing at extremely short distances (some as little as a few centimetres), allowing the photographer to get very close to the subject. feature can be utilised from up close or from a further distance. Like each and every Global Vision Lens, the Sigma 100-400mm Contemporary Art is handcrafted at our single factory in Aizu, Japan and undergoes individual evaluation before leaving Sigma’s facility.
Top Optical Performance Equivalent To That Of A Much More Expensive Lens
Since its release, the SIGMA 150-600mm f/5-6.3 DG OS HSM | Contemporary has won photographers over with its strong fundamental performance and exceptional image quality. The new lens retains all of this performance in a compact 400mm ultra-telephoto zoom package with a filter size of just 67 mm and weight of just 1.16 kg. Yet it also comes with the full range of features and functions expected of an ultra-telephoto zoom: optical stabiliser (OS), hypersonic motor (HSM) with updated algorithm for fast autofocus, focus limiter, and more. In addition, this uncompromising specification becomes customisable with the available SIGMA USB Dock accessory.
Compact Lens Design With Uncompromising Image Quality
In designing this lens, SIGMA strived to push both compactness and image quality to the limit. Four SLD (Special Low Dispersion) glass lens elements and an optimised power distribution help minimise optical aberrations. Moreover, by taking special care to minimise transverse chromatic aberration, which cannot be corrected via 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. control, SIGMA has ensured outstanding image quality throughout the zoom range.
Push-pull Zoom Mechanism Incorporated in Addition to Conventional Twist Zoom
For quick control of the angle of view, the zoom ring incorporates a push/pull mechanism in addition to the regular twist mechanism. The exclusive lens hood has also been designed to accommodate push-pull zooming and overall lens manoeuvrability. By making it possible to adjust the angle of view instantly, this lens gives photographers an even better chance of getting that crucial shot.
All-New Optical Stabiliser Unit With Exclusive Algorithm
Featuring a newly developed gyroscopic sensor and a new and exclusive algorithm, the all-new OS unit provides a powerful stabilisation effect. An acceleration sensor detects camera shake in any direction—horizontal, vertical, or diagonal. This technology allows the OS to stabilise the image very effectively, regardless of whether the camera is being held in horizontal or vertical orientation.
Shoot in Any Weather with 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.
