Sigma 12-24mm f/4 DG HSM ART Super Wide-Angle Zoom Lens, for Canon EF. Everything photographers require of an ultra-wide-angle zoom and more. The ultra-wide-angle zoom pioneer, SIGMA has developed and launched many extraordinary products in this category over the decades. Now SIGMA introduces an ultra-wide-angle zoom lens that is perfect for the era of ultra-high resolution digital cameras. To achieve these qualities without compromise, SIGMA has leveraged its lens design expertise and all of its leading-edge technologies. Advanced materials such as low-dispersion glass play a crucial role, while SIGMA’s advanced lens processing methods have made possible an aspherical lens of extremely large diameter. Outstanding image quality from center to edges When it comes to ultra-wide-angle lenses, photographers require outstanding image quality from the center of the image to the edges without any distortion. Such performance is particularly valuable in architectural photography. The lens also features lens elements made with 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. 80mm aspherical lens the largest in this lens class: The SIGMA 12-24mm F4 DG HSM / Art features 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. F4 brightness throughout the zoom range: With F4 throughout the zoom range, this lens is one stop brighter than conventional lenses. Photographers can now use a higher shutter speed that will crisply capture leaves fluttering in the breeze and other quick-moving subjects. Minimum focusing distance of 24cm/9.45: Leveraging the incredibly broad perspective of an ultra-wide-angle lens, photographers can compose close-up shots with impressively expansive backgrounds. At 24mm end of the zoom range. Newly designed HSM for nimble AF control: The newly designed Hyper Sonic Motor (HSM) is large, offers 1.3 times the torque of its predecessor. Even at low speeds, it offers exceptionally stable performance. Mount with dust- and splash-proof construction: The lens mount incorporates rubber sealing to protect the mount from dust and water drops. The front and rear lenses feature a water- and oil-repellent coating that is particularly useful when shooting in a drizzle, near ocean spray, and in a wide variety of other conditions. Art line delivers high-level artistic expression: Offering astonishing rendering performance that meets the highest standard, they are perfect for landscapes, portraits, still-lifes, close-ups, and casual snaps. They are made for the kind of photography that unleashes the inner artist. Compatible with Mount Converter MC-11: Mount Converter MC-11 allows you to use your SIGMA SA mount and SIGMA EOS mount (Canon-compatible) interchangeable lenses with the Sony E-mount camera body. Owners of multiple camera systems can get even more out of their valuable lens assets.
