Sigma 12-24mm f/4.5-5.6 MKII DG HSM Lens - Nikon Fit

Manufacturer Refurbished, Minor Marks to Body of Lens, Hence Price, 3 Years Warranty when Registered with Sigma UK

The 12 - 24mm is a classic Sigma ultra-wide angle zoom lens that is great for producing an exaggerated perspective to really add impact to your pictures. With a fine heritage dating back more than 30 years, this compact lightweight design makes it an ideal companion for travelling as well as a great tool for your architectural, landscape, and creative shots. Sigma's unique Super Multi-Layer Coating on the lens elements reduces flare and ghosting that can ruin your shots and the high-speed autofocus system (HSM) ensures quiet and high-speed autofocus. As you would expect from this reputable manufacturer, this zoom has superior peripheral brightness and provides sharp and high contrast images even at the maximum apertures. The Photographer magazine said that they had never seen anything like it in their lives with that common feature of ultra wide lenses, curvature at edges being virtually non-existent and Amateur Photographer agreed, commenting that the lens had been corrected to exceptional standards.

Ultra wide angle zoom lens compatible with digital SLR cameras with a 35mm full frame image sensor.
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 With 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.

Exaggerated perspective
The wide-angle of view produces striking images with exaggerated perspective, enabling photographers to emphasize the subject.

Compact construction
Incorporation of four aspherical lenses provides a compact construction with a diameter of 85mm (3.3"), overall length of 120.2mm (4.7") and weight of 670g (23.6oz.). The compact construction makes this lens ideal for travel photography.

Quiet and high speed autofocus
Hyper Sonic Motor 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. Petal-type hood This lens is equipped with a Petal-type hood to block out extraneous light and reduce internal reflections.

DG 
Sigma’s DG lenses are designed for cameras with a full-frame sensor, but cameras with a cropped sensor can also take these lenses. These are large-aperture lenses with wide angles and short minimum focusing distances. With an abundance of peripheral illumination, they are ideal lenses for Digital SLR Cameras whilst retaining suitability for traditional 35mm SLRs.

HSM (Hyper-Sonic Motor)
This lens uses a motor driven by ultrasonic waves to provide a quiet, high speed AF.
