Product Description
Sigma provides the new ultra-wide angle zoom lens from 15mm and this lens is the first of its kind in the world. It can be useful for images of landscapes, large buildings, group photographs or even more. The perspective that changes with the angle-of-view gives picture an extraordinary feeling. Delicate compositions can be adjusted by lens zooming and this is helpful for close-up photography. Provides deep depth of field with its short focal length for amazing photographic expressions. This ultra-wide zoom lens covers a large wide-angle range from 15 mm to 30 mm. With a minimum focusing distance of 30 cm(11.8 inches) throughout the entire zoom range, it is an ideal lens for Digital SLR Cameras. It incorporates hybrid aspherical lens in the front lens group to minimize distortion and astigmatism, and molded glass aspherical lens in the rear lens group to minimize spherical aberration. Minimization of the distortion is a most important issue for zoom lens, but Sigma has succeeded, to provide image quality with minimal distortion by employing aspherical lenses. This lens in corporates an internal focusing system, which eliminates front lens rotation. Since focusing do not change its overall length, this lens is easy to hold and use. Also it is allowing the use of a Petal-type Hood. The lens also incorporates Dual-Focus (DF) mechanism. It is easy to hold the lens, since the focusing ring does not rotate during auto-focus, yet it provides adequate focusing torque of the focusing ring during manual focusing of the lens.
Designed exclusively for Nikon digital SLR cameras capable of wide-angle photography, the Sigma 10-20mm f/4-5.6 lens is a powerful tool for landscape photography and other wide-angle applications. The lens offers an ultra-wide angle of view of 94.5 to 56.8 degrees, with three special low dispersion (SLD) glass elements and three aspherical lenses providing optimum image quality throughout the entire zoom range. The lens also incorporates a Hyper Sonic Motor (HSM) to ensure quiet, high-speed autofocusing in addition to full-time manual focusing. Other features include a close focusing distance of 9.4 inches, a non-rotating lens barrel that perfectly suits the petal-shaped lens hood (included), and a one-year warranty.

From the Manufacturer
The 10 to 20 millimeters f4 to 5.6 EX DC HSM lens allows enjoyment of super wide-angle photography and it is a very powerful tool for indoor shooting and landscape photography with APS-C size image sensors of digital SLR cameras.
Wide angle of view (102.4 degrees at 10 millimeters and 63.8 degrees at 20 millimeters) offers the photographer greater freedom of expression.
Three SLD glass elements are employed for effective compensation of color aberration, which is a common problem with super-wide angle lenses. One piece of glass mold and two hybrid aspherical lenses, offer excellent correction for distortion, as well as all types of aberration.
This lens is equipped with an inner focusing system, and the models which are equipped with HSM system provide quiet, high speed autofocus shooting and also offer full time manual focusing. It has a minimum focusing distance of 24 centimeters (9.4 inches) at all focal lengths. The non-rotating lens barrel perfectly suits the petal shaped lens hood. A circular polarizing filter can also be used conveniently.
- It covers a superwide angle of view 102.4 to 63.8 degrees
- Three pieces of Special Low Dispersion (SLD) elements and three aspherical lens elements produce top quality optical performance.
- Inner focusing system ensures the length of the lens remains unchanged whilst controlling aberrations.
- Equipped with HSM (Hyper Sonic Motor) system
- Minimum focusing distance of 24 centimeters (9.4 inches) at all focal lengths
- Relatively compact, lightweight for an ultra wide-angle zoom lens
