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 Technical Details:
Premium FLD glass, with performance equal to flourite, and seven SLD glass elements allow for outstanding image quality. A large diameter aspherical lens, a complicated element to manufacture, allows for a stunning level of brightness. This complicated optical formula creates outstanding image quality throughout the focal range, and even at the widest of apertures. An updated AF algorithm makes for smooth, accurate and fast autofocusing while multi layer coating control flare and ghosting.
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.
