Additionally, this design also contributes to high detail rendering capabilities throughout the entire focusing range. ![]() This floating system helps to realize a minimum focusing distance of 1.3' with a maximum magnification of 1:5.6. Floating Systemīy employing a floating system, the distance between glass elements is adjusted during focusing in order to limit the amount of lens movement required when shooting. Super Multi-Layer CoatingĪ Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions. This design also lends itself to minimizing vignetting throughout the aperture range for greater clarity and detail across the image frame. In designing the lens with a large 85.4mm diameter, and placing the widest elements within the front group, greater peripheral brightness is more easily attained when working with larger apertures. This helps to ensure maintained image sharpness, clarity, and contrast regardless of focus point or aperture setting. Three SLD (Special Low Dispersion) glass elements have been incorporated within the lens design to correct for axial chromatic aberration throughout the entire focusing range. By reducing these aberrations, this lens is also well-suited to astrophotography or other situations with point-light sources due to its ability to suppress blur near the edges of the frame. This design also works to minimize vignetting, color blur, and other distortions help to produce natural and pleasing bokeh for selective focus and shallow depth of field techniques. A molded glass aspherical element corrects for sagittal coma flare and enables full use of the fast f/1.4 maximum aperture with maintained sharpness and clarity. This lens has been designed using an advanced optical structure to achieve both high resolution and sharpness along with an aesthetic out-of-focus quality for greater subject separation. Sigma Global Vision - ArtĪs part of the Art line within Sigma's Global Vision series, this lens' is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications. This AF motor also permits full-time manual focusing control for refined precision by simply turning the focus ring at any time. A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and color fidelity.Ī Hyper Sonic AF Motor, along with an optimized AF algorithm, produces quiet, smooth, and fast autofocus performance that benefits this lens' use in a wide variety of situations. The lens' large diameter and floating system also help to correct for vignetting to ensure maintained peripheral brightness. These elements, coupled with an advanced optical design, work to minimize sagittal coma flare and chromatic aberrations in order to provide high image sharpness and clarity. They cannot be converted to either an APS-C or a Full Frame format.The Canon EF mount Sigma 50mm f/1.4 DG HSM Lens is a fast standard-length prime designed to achieve high optical performance through the incorporation of both three Special Low Dispersion glass elements and one molded glass aspherical element. Sigma lenses currently from the Contemporary, Art or Sports line, in Sigma, Canon, Nikon, Sony, Pentax mounts can be converted to Sigma, Canon, Nikon, Sony or Pentax*. Sigma will convert the current mount of your Sigma Global Vision lens to another of your choice. The Sigma 50mm 1.4 lens is the new exceptional standard, standard prime. ![]() ![]() 13 elements in 8 groups allow for unsurpassed performance even at wide apertures and close-up photography is easily managed with a minimum focusing distance of 40cm. A Hyper Sonic Motor (HSM) ensures quiet, smooth and accurate autofocusing and paired with Special Low Dispersion (SLD) glass and Super Multi-Layer coating, the 50mm 1.4 is a high performance lens for the modern DSLR sensors. ![]() With a large 1.4 aperture, the Sigma 50mm 1.4 prime lens is a pro level performer for shooting everything including portrait photography, landscape photography, studio photography and street photography. The staple Sigma 50mm 1.4 DG HSM has been redesigned and reengineered to set a new standard for the Art line.
