The Sigma 12-24mm f4 DG HSM Art is a premium full frame wide angle zoom designed to have minimal distortion in its wide angle imagery. Part of the Art line, the Sigma 12-24mm F4 DG HSM Art was created from decades of experience manufacturing wide-angle lenses. FLD glass elements, with performance equal to fluorite, provide for exceptional image quality while an updated Hyper Sonic Motor (HSM) uses 1.3X the torque for quick AF. A constant F4 aperture through the entire zoom range allows for greater ability in low light compared to previous models and the use of the largest aspherical element in the industry controls distortion, ghosting and flaring. An emphasis on edge to edge performance brings stunningly sharp and contrasty images to life. Ideal for many types of photography, the 12-24mm f4 Art is perfect for landscape photography, architecture photography, interior photography and much more.
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 color 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 Technical Details:
The lens also features lens elements madewith FLD (“F” Low Dispersion) glass, which is equivalent to fluorite in performance, and an optimized power distribution.Together, these features help minimize distortion, transverse chromatic aberration, and coma flare. As a result, image quality is outstanding across the image, all the way to the edges. It also features an 80mm large-diameter molded glass aspherical lens—the largest such element in this class of lens. This lens is highly effective in minimizing distortion, spherical aberration, and coma flare.
More Reasons to Choose a SIGMA Lens:
Sigma inspects each and every lens with their proprietary Foveon-based A1 MTF measuring system, which guarantees every lens meets their high optical standards.
“Made in Japan” craftsmanship is what makes SIGMA lenses high-performance, high-quality, and high-end.
