Highly effective dust- and splash-proof structure: Like SIGMA's Sports line lenses, the 14-24mm F2.8 DG HSM | Art features a highly effective dust- and splash-proof structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection, allowing photographers to work in all types of weather. In addition, the front of the lens is protected by a water- and oil-repellent coating that makes cleaning easy. The high-speed, high-accuracy autofocus helps photographers react in an instant to get those special shots.
Aspherical lens elements: Aspherical lens elements used for SIGMA 18-35mm F1.8 DC HSM | Art (left) and SIGMA 14-24mm F2.8 DG HSM | Art (right). This premier optical technology promises to set a new standard for excellence in ultra-wide-angle lenses.
Smooth bokeh and minimised flare: The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image. From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA's Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions.
Front Conversion Service (Optional): To support the needs of virtual reality creators engaged in multi-camera videography, SIGMA is offering the new Front Conversion Service for the 14-24mm F2.8 DG HSM | Art lens . With this service, SIGMA converts the petal-type hood of the lens to an exclusive round component that lacks a light-blocking function. The new front helps prevent the lens from interfering with other lenses or from casting a visible shadow during multi-camera work. This is a for-fee service performed exclusively by SIGMA.
REAR FILTER HOLDER FHR-11 (Optional): The Rear Filter Holder FHR-11 is an accessory that enables photographers to use a filter sheet with the lens. By attaching it to the rear of the lens, it will allow more freedom of expression. * Only available for the Canon mount lens. There are no plans for the development in SIGMA and Nikon mounts.
High-precision, rugged brass bayonet mount: The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
