The Sigma 28-105mm F2.8 DG DN | Art is a powerful wide-angle to medium telephoto lens with a bright F2.8 aperture throughout. This full-frame zoom is compatible with Sony mirrorless cameras and combines outstanding optical performance, superb build quality and a range of pro grade features. This versatile lens includes high-speed AF with HLA technology, aperture ring and a rugged, compact and lightweight (weighs less than 1kg) structure, making it an ideal all-round lens for both stills and video. Superior optical performance The Sigma 28-105mm F2.8 DG DN | Art operates without compromise, suppressing aberrations very effectively within each lens group, and throughout the entire zoom and focal range. This ensures the lens has a consistent performance even with such a long zoom range. This is thanks to the lens’s premium optical design, which includes two FLD, one SLD and five aspherical elements, the first grouping of which uses a large-diameter φ66.4mm element. Superb portability The Sigma 28-105mm F2.8 DG DN Art has been designed with portability in mind. It combines five aspherical elements effectively in place to shorten the overall length, and a magnesium-alloy construction around the mount, keeping the weight of the lens to less than 1kg. This ensures the lens has superb portability similar to shorter standard zoom lenses, while providing a wider zoom range. Versatile F2.8 aperture With its fast aperture across the whole focal range, the Sigma 28-105mm F2.8 DG DN Art is a true workhorse lens that can be used for almost any type of photography. Scenic photographers can shoot wide-angle landscapes, using the F2.8 aperture for low-light scenes and twilight urban views, while the middle focal lengths tackle dimly lit documentary and street subjects. At the long end, popular portrait focal lengths from 85mm and 105mm, combined with the F2.8 maximum aperture, produce a shallow depth-of-field that will isolate a subject for beautiful bokeh. Linear motor HLA for rapid and accurate AF The lens incorporates a linear motor HLA (High-response Linear Actuator) that delivers a maximum drive speed, ensuring responsive, precise and smooth AF. With its high level of quietness, the motor also provides noise-free video capability. Superb close-up performance Achieving a minimum focus distance of just 40cm across its entire zoom range, this lens can get you closer to your subject, filling the frame with detail and texture. At its 105mm setting, this creates a very useful maximum magnification ratio of 1:3.1 for powerful macro-style results. Minimal focus breathing Vital for film makers who demand consistent framing, the lens has been designed to keep focus breathing to a minimum. This ensures that any changes to the angle-of-view due to focus shift are minimized across the entire zoom range, ensuring natural-looking focus pulls when recording video, and easier image alignment when focus stacking. Nano porous coating and super multi-layer coating Using advanced simulation technology, flare and ghosting have been largely eliminated, ensuring that the lens renders rich, high-contrast results in all conditions. In addition, SIGMA’s Nano Porous Coating and Super Multi-Layer Coating have been applied to further suppress flare and ghosting. Weather resistant structure The lens has a dust and splash-resistant structure that keeps it free of contaminants in harsh outdoor environments. The front element also features a water- and oil-repellent coating that helps keep it clean in adverse shooting conditions. Aperture ring for improved ergonomics For quick changes to exposure, or a more traditional way of shooting, the lens is equipped with a dedicated aperture ring, allowing the user to change aperture via the lens if preferred. An aperture ring click switch is a useful tool for film-makers, and a lock switch helps ensure the aperture ring is not knocked out of its setting accidentally.
