Sigma AF 12-24mm F4.5-5.6 II DG HSM Lens for Canon Overview
The Sigma 12-24mm f/4.5-5.6 EX DG ASP HSM II Wide-Angle Lens for Nikon is designed for use with full-frame digital cameras, and offers a dramatically ultra-wide, minimally distorted zoom lens with a field of view from 122° to 84.1°. This range makes it ideal for the tightest of interiors, as well as for dramatic landscape photography. Using a camera with an APS-C sensor will give you an effective range of 17-35mm, also a very attractive wide-angle zoom range.Features: Designed for use with full frame digital cameras. May also be used with smaller APS-C size sensors with a corresponding effective increase in focal length to about 17-35mm with most cameras One SLD and four FLD glass elements compensate for color aberration and provide high image quality Three glass mold elements and one hybrid aspherical lens give advanced performance and compact, lightweight construction Super Multi-Layer Coating reduces flare and ghosting Superior peripheral brightness--provides sharp, high contrast images even at the maximum apertures HSM (Hyper-Sonic Motor) ensures a quiet and high-speed auto focus, with full-time manual focus override Minimum focusing distance of 11" (28 cm) throughout the entire zoom range Splash-proof design for use in harsh conditions Maximum magnification ratio of 1:6.4 A front cap adapter, front/rear lens cap and carrying case are included with the lens Uses rear-mount gelatin filters
Ultra wide angle zoom lens compatible with digital SLR cameras with 35mm full frame image sensor.
This ultra wide angle zoom lens incorporates the latest optical design provides superior performance. FLD ("F" Low Dispersion) glass elements, which have performance equal to fluorite, and SLD (Special Low Dispersion) glass elements provide excellent correction of color aberration. Aspherical lenses give advanced performance with a compact and lightweight construction. The Super Multi-Layer Coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. Incorporation of HSM ensures quiet and high speed autofocus as well as full-time manual focus capability. This lens has superior peripheral brightness and provides sharp and high contrast images even at the maximum apertures.
Ultra wide angele zoom: Sigma made it first
Sigma designed and produced the first wide-angle zoom lens, the "zoom gamma 21-35mm F3.5-4", in 1979. Sigma has since introduced a number of wide angle zoom lenses. The SIGMA 12-24mm F4.5-5.6 II DG HSM is the successor of the SIGMA 12-24mm F4.5-5.6 EX DG ASPHERICAL / HSM which was launched in November 2003. This ultra wide angle zoom lens is ideal for digital SLRs with a 35mm full frame image sensor and incorporates the latest optical design.
Superior image quality
The ultra-wide angle zoom lens is possible due to large diameter of the front lens. Four FLD ("F" Low Dispersion) glass elements, which have performance equal to fluorite, and one SLD (Special Low Dispersion) glass element provide excellent correction of color aberration. Three glass mold elements and one hybrid aspherical compensate for all types of aberration and ensure high optical performance.
FLD glass is the highest level low dispersion glass available with extremely high light transmission. This optical glass has a performance equal to fluorite glass which has a low refractive index and low dispersion compared to current optical glass. It also benefits from high anomalous dispersion. These characteristics give excellent correction for residual chromatic aberration (secondary spectrum) which cannot be corrected by ordinary optical glass and ensures high definition and high contrast images.
Super Multi-Layer Coating
Due to the ultra-wide angle, the front of this lens is very large. Sigma's Super Multi-Layer Coating reduces flare and ghosting which could otherwise create problems when extraneous light hits the lens' front element. It also provides sharp and high contrast images throughout the entire zoom range.
Superior peripheral brightness
The design of front lens group minimizes light fall off and increases peripheral brightness.
The wide-angle of view produces striking images with exaggerated perspective, enabling photographers to emphasize the subject.
Incorporation of four aspherical lenses provides a compact construction with a diameter of 85mm (3.3"), overall length of 4.7" and weight of 23.6oz. The compact construction makes this lens ideal for travel photography.
Quiet and high speed autofocus
HSM indicates lenses equipped with a Hyper Sonic Motor, driven by ultrasonic waves. Incorporation of HSM (Hyper Sonic Motor) ensures quiet and high speed autofocus, while allowing full-time manual focus override.
Inner focusing system
This lens incorporates an inner focusing system, which eliminates front lens rotation which also minimizes fluctuation of aberration caused by the focusing system
In a conventional lens, focusing requires an extension of the entire lens or the front lens group. However, to better accommodate autofocusing mechanisms and closeup photography, a need has arisen for lenses that do not change their length during focusing or suffer from focus-dependent variation in aberration. Therefore, Sigma has developed focusing systems that only move elements within the lens barrel. These incorporate smaller and lighter moving lens elements which help improve auto-focus speed. With their unchanging barrel length and small variation in the center of gravity, these lenses also enhance balance and stability for the photographer. Furthermore, since the front of the lens does not rotate, polarizing filters can be used with extra convenience.
