SIGMA PHOTO DG HSM NA F/1.4 Wide Angle Lens 28 mm

28mm angle of view used to be a representative wide-angle in the era of film cameras, and attracts many fans even today. To accommodate the request from many photographers who expressed the strong interest in using the familiar 28mm with Art line quality, SIGMA produces the SIGMA 28mm F1.4 DG HSM | Art, based on the know-how gained through development of the Art F1.4 prime lens lineup released so far. This newest traditional wide-angle lens, advantaged by the latest design and materials, as well as the processing technologies, is now available from SIGMA’s Art line. Features: Best-in-class performance: - This lens incorporates two FLD (“F” Low Dispersion) glass elements and three SLD (Special Low Dispersion) glass elements. In addition, it effectively arranges three aspherical lenses, including a large-diameter aspherical lens to provide thorough correction of magnification chromatic aberration —encountered particularly in wide-angle lenses. This offers high resolution over the entire sensor, while sagittal coma flare is thoroughly corrected and distortion is also minimized to the fullest. Excellent performance is delivered in street photography, as well as shooting landscapes and night skies. Designed to meet all shooting conditions: - The water- and oil-repellent coating on the front lens element, together with the dust and splash resistant structure*, ensures excellent performance even in the most challenging shooting conditions. The high-speed AF, thanks to the HSM (Hyper Sonic Motor) with an updated algorithm, captures instantaneous photography movement. water- and oil-repellent coating: - The front lens element incorporates 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. Dust and Splash Resistant Structure: - This lens features a highly effective dust and splash resistant structure* with special sealing at the mount connection, manual focus ring, and cover connection, allowing photographers to work in all types of weather. High-speed AF: - The high-speed AF, thanks to the HSM (Hyper Sonic Motor) with an updated algorithm, captures instantaneous photography movement. Hood with lock: - Features a hood with lock to prevent dropping the hood. SIGMA’s industry-leading wide-angle collection: - With the launch of this lens, the lineup of large-diameter wide-angle prime lenses compatible with 35mm full-frame has expanded to five, ranging from 14mm to 35mm. All lenses except for 14mm have an F1.4 brightness (F1.8 for 14mm), enabling photographers to choose the angle of view that best suits them, process attractive bokeh in the background, and capture their imagination. Compatible with Canon Lens Aberration Correction: - The Canon mount version of this lens is compatible with the Canon Lens Aberration Correction function.* Matching 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. Designed to minimize flare and ghosting: - 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. 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. Rounded diaphragm: - The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image. Nikon electromagnetic diaphragm mechanism included: - The Nikon mount version of this lens includes an electromagnetic diaphragm mechanism that allows it to receive the appropriate signals from the camera body. This feature ensures precision diaphragm control and stable Auto Exposure (AE) performance during continuous shooting. Essentials: You´ll find our philosophy and craftsmanship in every product: Our new lineup fully expresses our approach to lenses and photography itself. All of our lenses belong to one of three lines—Contemporary, Art, or Sports—all of which share our development philosophy and advanced manufacturing system. High performance, high quality, and high end in every respect, these lenses give people who love photography lasting value and consistent, exciting results. The secret is our passion for craftsmanship that we put into every production process and every product.
