It has the optical performance of a fixed focal length lens and is designed for video photography. The wide-normal focal length means a lighter camera bag without compromising on image quality.<\/p>\n<h3>Design and performance<\/h3>\n<p>The lens has a total of 17 elements in 11 groups, including four aspherical and four special low-dispersion elements. These minimise flare and ghosting and reduce various aberrations. As a result, optical performance matches or exceeds that of other Sigma Art lenses, including <a href=\"https:\/\/devbed.fotomonza.com\/en\/kauppa\/sigma-18-35-f1-8-art-dc-hsm-eos\/\">18-35mm f\/1.8 DC HSM Art<\/a> -lens. Together with its 11-bladed, rounded dimmer plate, the design promotes sharpness and a large, smooth bokeh when used wide open.<\/p>\n<p>In addition to the maximum aperture of F\/1.8, the lens maintains a minimum focusing distance of 28 cm throughout the zoom range. It achieves a maximum magnification ratio of 1:4.8 at its longest focal length, increasing depth of field and versatility in confined spaces.<\/p>\n<h3>Video production<\/h3>\n<p>The lens is designed for video creation. Its bright f\/1.8 aperture and wide-normal zoom range make it a versatile tool, ideal for individual photographers shooting on the move. The built-in zoom design maintains overall length during use, making it easy to balance on gimbals. The design also restrains focus shake for smooth movement throughout the focal length range.<\/p>\n<p>Sigma's fast, high-response linear actuator autofocus remains both quiet and accurate, while manual focus is enhanced by click and lock mechanisms.<\/p>\n<ul>\n<li>Two AFL buttons<\/li>\n<li>Focus mode switch<\/li>\n<li>Water- and oil-repellent coating on the front element<\/li>\n<li>Dust and splash resistant design<\/li>\n<li>Durable brass bayonet mount<\/li>\n<\/ul>\n<h2>Technical specifications:<\/h2>\n<ul>\n<li>Firing range: 17 - 40mm (35mm Equivalence: 25.5 - 60mm)<\/li>\n<li>Aperture: maximum: f\/1.8, minimum: f\/16<\/li>\n<li>Lens mount: Canon RF<\/li>\n<li>Lens format coverage: APS-C<\/li>\n<li>Angle of view: 76.5\u00b0 - 37.1\u00b0<\/li>\n<li>Minimum focusing distance: 28 cm<\/li>\n<li>Magnification ratio: 1:4.8 macro reproduction ratio, 0.21x magnification<\/li>\n<li>Optical structure: 17 elements in 11 groups<\/li>\n<li>Dimmer\/Iris leaves: 11, Rounded<\/li>\n<li>Focus type: autofocus<\/li>\n<li>Image stabilizer: No<\/li>\n<li>Filter size: 67 mm (Front)<\/li>\n<li>Dimensions: \u00f8: 72.9 x L: 115.9 mm<\/li>\n<li>Weight: 560 g<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>The Sigma 17-40mm f\/1.8 DC Art lens for Canon RF cameras offers a wide zoom range and excellent optical performance.
