Equivalent to 24-450mm in 35mm format, this portable lens covers everything from wide-angle for landscapes and interiors to super-telephoto for sports, wildlife and aviation.Maximum magnification ratio of 1:2 at 70mm for striking close-upsWith a maximum magnification ratio of 1:2 at 70mm, the Sigma 16-300mm F3.5-6.7 DC OS | Contemporary provides excellent close-up performance, perfect for capturing flowers, insects and other small subjects in great detail. With a maximum magnification of 1:3 at the wide end and 1:4 at the telephoto end, photographers have access to a huge range of creative expression.Small, lightweight and portableDespite its impressive zoom range of 16-300mm, the Sigma 16-300mm F3.5-6.7 DC OS | Contemporary prioritizes high portability, measuring just 73.8mm in diameter by 121.4mm in length and weighing just 615g. This is achieved through advanced mechanical and optical design, including a high refractive index glass element with significant thickness variation and an aspherical lens element.Accelerated AF speed and accuracy with HLA autofocus motorTo help photographers capture even the most fleeting moments, the Sigma 16-300mm F3.5-6.7 DC OS | Contemporary uses a High-response Linear Actuator (HLA) motor to achieve high-speed autofocus functionality with excellent drive accuracy.Outstanding optical stabilization powered by the OS2 algorithmInspired by the same technology that powers Sigma's super-telephoto lenses used by professional wildlife and sports photographers, the Sigma 16-300mm F3.5-6.7 DC OS | Contemporary features 6 stops of optical stabilization at the wide end and 4.5 stops at the telephoto end. The latest OS2 optical stabilization algorithm provides superior image stabilization to mitigate the effects of camera shake, helping photographers achieve blur-free results without the need for a tripod, even when shooting in low light and at full zoom.Equipped with a zoom lock switch at the wide endThe Sigma 16-300mm F3.5-6.7 DC OS | Contemporary features a zoom lock switch that can be fixed at the wide end to prevent the lens from extending.Dust- and splash-resistant structure and water-repellent coatingDesigned to help photographers work in all environments, the Sigma 16-300mm F3.5-6.7 DC OS | Contemporary features a dust- and splash-resistant structure for use in harsh conditions. In addition, the front element features a water- and oil-repellent coating that helps keep the lens free of contaminants.Consistently high image quality across the entire zoom rangeThanks to its advanced optical design with 1 FLD, 4 SLD and 4 aspherical elements, the lens has excellent aberration correction and delivers sharp results throughout the whole zoom and focus range.Engineered to minimize flare and ghostingBy measuring light incidence under all conditions and using advanced simulation technology, the Sigma 16-300mm F3.5-6.7 DC OS | Contemporary guarantees superior resistance to flare and ghosting, allowing photographers to capture crisp, clear images in even the most challenging lighting conditions - just as an all-in-one lens should.Suppressed focus breathing for consistent framingThe Sigma 16-300mm F3.5-6.7 DC OS | Contemporary is designed to effectively suppress focus breathing, making it a perfect choice for filmmakers as well as photographers working with multi-shot techniques such as focus stacking. Throughout the zoom range, changes in angle of view are kept to an absolute minimum when changing focus.HLA (High-response Linear Actuator)HLA is Sigma's proprietary linear motor. It drives the focus lens directly without going through gears or other mechanical parts, resulting in quiet, high-precision autofocusing.Inner focus systemTo increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.OS2OS2 is the newly developed optical stabilizer algorithm. Compared to the previous algorithm used by Sigma lenses, OS2 improves the effect of optical stabilization significantly.Compatible with Lens Aberration CorrectionMatching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.Water and oil repellent coatingIncorporates a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.Zoom lock switch (Wide end)The zoom lock switch fixes the zoom ring at the widest end, preventing it from rotating and causing the lens barrel to extendunder its own weight during transportation.Dust and Splash Resistant StructureThis lens features a highly effective dust and splash resistant structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection.Super Multi-Layer CoatingSigma's own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections with in the lens. All lenses in the current Sigma range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, Sigma's Super Multi-Layer Coating is highly effective, assuring images of outstanding contrast.Linear focus / Non-linear focus (for L-Mount only)A focus movement method of interchangeable lenses for mirrorless cameras (DN lens) in relation to the rotational angle of the focus ring during manual focusing.With "non-linear focus," the amount of focal point movement varies depending on the focus ring rotational speed.With linear focus, if the focus ring rotational angle is the same, the amount of focal point movement remains the same regardless of the focus ring rotational speed.High-precision, rugged brass bayonet mountThe brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.Rounded diaphragmThe polygonal shape of a conventional iris diaphragm causes out-of-focus light points to appear polygonal. A rounded diaphragm is designed to produce rounded out-of-focus light points when opened to near maximum aperture. This creates attractive bokeh effects in many situations, such as when photographing a subject against an out-of-focus surface of water from which light is being reflected.
