Ultra-wide-angle 12-24mm F4 DG HSM by Sigma
focusing distance of 24cm
dust- and splash-proof
Hyper Sonic Motor (HSM)
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. The SIGMA 12-24mm F4 DG HSM Art offers an optimal package of center-to-edge image quality, minimized distortion, and minimum focusing distance. 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.
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 new SIGMA 12-24mm F4 DG HSM Art leverages SIGMA’s accumulated expertise in the processing and manufacture of aspherical lenses and incorporates multiple aspherical lenses produced with precision glass molding. 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.
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. A constant aperture during zooming also makes this lens exceptionally easy to use.
Minimum focusing distance of 24cm
Leveraging the incredibly broad perspective of an ultra-wide-angle lens, photographers can compose close-up shots with impressively expansive backgrounds.
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.
