Designed with state of the art technology, the Sigma Art 50mm F1.4 DG HSM achieves remarkably high resolution and astonishing rendering performance over the entire image, while delivering a beautiful bokeh effect. Its large aperture makes this lens the professional's choice for shooting everything including portraits, landscapes, studio photography and street photography. Aberrations such as sagittal coma flare and colour distortion are minimized and corrected through the use of molded glass aspherical lens elements and SLD (Special Low Dispersion) glass elements. This also makes it ideal for astronomical photography because of the reduced blur of point light sources near the edge of the image.
This lens provides unsurpassed performance even at wide apertures, and even allows for close-up photography with a minimum focusing distance of 40cm. Its Hyper Sonic Motor ensures a high auto-focus speed, and the incorporation of a rounded 9-blade diaphragm creates an attractive blur to the out-of-focus areas of the image. For resiliency and accuracy, the bayonet mount is made of brass.
SIGMA DG Lenses are High-performance SLR lenses with full-frame sensor coverage Designed to deliver the ultimate in performance on full-frame digital SLRs, Sigma DG lenses also bring out the best in 35mm SLR film cameras and APS-C size DSLRs. Remarkable image rendition is achieved by comprehensive correction of aberrations and distortions. Special care is taken to thoroughly minimize colour fringing caused by lateral chromatic aberration, which is particularly noticeable at high resolution in digital photography. DG lenses can offer both high contrast and subtle tonal gradations, unmarred by flare and ghosting, thanks to Sigma's digitally optimized optical design and original Super Multi-Layer Coating technology, which suppress reflections between image sensor and lens surfaces. Large image circles assure ample peripheral bright- ness to prevent vignetting.
The HSM (Hyper Sonic Motor) ensures a silent, high-speed AF function. By optimizing the AF algorithm, smoother AF is achieved. Also, this lens offers full-time MF by rotating the focus ring of the lens while auto focusing. Without changing the AF/MF Focus Mode Switch, it allows faster focus adjustment.
What makes a Sigma Art lens an “Art” lens?
Sigma’s Art line lenses are designed to meet the expectations of users who value a creative, dramatic outcome above compactness and multi-function. Along with landscapes, portraits, still-life, close-up and casual snaps, they're perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much expressive scope when capturing architecture, starry skies, underwater shots and many other scenes.
The L-Mount is born from a partnership between Leica, Panasonic, and Sigma, providing a robust mount with compatibility between all three brands.
