50mm F1.4 Dg Dn Art Lens Sony E Mount

The Sigma 50mm F1.4 DG DN Art is s fast-aperture, full frame prime lens designed for Sony E-mount mirrorless cameras. This all-round optic is ideal for portrait, wedding, street, landscape photography and is an excellent option for video shooting. It offers fast, precise autofocus and super-smooth bokeh in a compact and lightweight body. Optical performance Employing the latest optical design technology, the lens is constructed of 14 elements in 11 groups, including one SLD (Special Low Dispersion) element and three apsherical elements. It delivers significant improvements to sagittal coma flare and effectively suppresses various aberrations such as astigmatism and field curvature, which cannot be corrected digitally. It boasts an ultra-wide aperture of F1.4, making it ideal for low-light photography such as concerts, interiors and weddings. It also delivers a very shallow depth-of-field for background blur, which is perfect for creating stand-out portraits. The bokeh is smooth and attractive, and thanks to the lenss 11 diaphragm blades, the out-of-focus highlights are nicely rounded. Even when working wide-open at F1.4, photographers can be assured of razor sharp edge-to-edge results. Ultra-fast AF motor The Sigma 50mm F1.4 DG DN | Art is the first DG DN lens in the Art line to incorporate Sigmas HLA (Highresponse Linear Actuator) autofocus motor technology. This ensures fast, accurate and near-silent focusing, and despite its ultra-wide aperture, exceptionally fast tracking performance. Owing to the power of the HLA motor, Sigma were able to use a single double-sided aspherical element as the focusing lens - this has delivered both autofocus and optical design benefits. Robust and compact design The Sigma 50mm F1.4 DG DN | Art is a light and compact lens that feels well-balanced on a full-frame mirrorless camera without compromising on optical performance. The lenss build quality is superb, and meets the very high standards expected from a Sigma Art line lens. With a dust and splash-resistant structure, a rubber seal around the mount, and a water- and oil-repellent coating on the front-element, this lens suitable for use in difficult shooting conditions. The outer barrel is constructed of TSC (Thermally Stable Composite), which has a similar thermal expansion rate to aluminium. This means the metal inner barrel and the TSC outer barrel behave in a similar way as temperatures change, ensuring a consistent performance in all environments. Advanced feature-set designed for professionals The lens barrel is equipped with a range of useful functions. As well as a manual aperture ring, the lens has an Aperture Ring Click switch, which allows users to switch between stepped, third-stop aperture increments and a smooth, click-free action. This is particularly useful for videographers who may want to use the aperture to adjust exposure seamlessly while filming. The aperture ring can be locked with lock switch. The lens has an AFL button, which can be customised to perform a range of different functions (depending on camera model). Also on the lens barrel is an Focus Mode switch, a rubberised focus ring with a smooth, fluid-like movement, and a robust, petal-type lens hood with lock button. The hood also has a rubberised grip for easy attachment and removal.
