  • Super Multi Coating reduces flare and ghosting that tends to occur when using digital SLR cameras.
  • This large Aperture Standard Zoom lens extends shooting opportunities.
  • Designed Specially For Digital SLR Cameras.

This lens offers a large aperture of F2.8 over its entire range of focal lengths and its large depth of field offers greater freedom of creative expression.

This lens is perfectly suited for low light conditions indoors or at dusk. It covers wide angle to medium telephoto and is ideally suited to a wide range of subjects. It is an ideal large aperture standard zoom lens for digital SLR cameras featuring APS-C size image sensor.

EX Lens Series - Excellence Of Engineering And New Technology. The characteristics of digital SLR cameras were taken into consideration when designing the lens power layout. A Special Low Dispersion (SLD) glass lens element provides effective compensation for lateral chromatic aberration, which is likely to occur with digital SLR cameras. The use of two aspherical lens elements provides correction for various aberrations and makes high quality images a reality throughout the entire zoom range.

Compact And Lightweight, Yet Robust - A Special Low Dispersion (SLD) lens and two aspherical lens elements provide excellent correction for all types of aberrations. The design produces a compact and lightweight, yet robust, construction with an overall length of 84.1mm (3.3in.) and maximum diameter of 74.1mm (2.9in.) and weight of 445g (15.7oz).

Most Appropriate Coating for Digital Products - Super Multi Layer (SML) coating gives the best color balance and reduces flare and ghosting from which digital cameras tend to suffer.

Minimum Focusing Distance of 28cm (11in.) throughout the entire zoom range - This lens has a minimum focusing distance of 28cm (11in.) throughout the entire zoom range which is very convenient for close-up photography.

Inner Focus System - The lens is equipped with an inner focusing system. The non-rotating front lens element makes the lens suitable for using its petal-type lens hood and circular polarizing filters.

New Optical Design Effectively Reduces Vignetting - This lens has excellent correction for vignetting which is a common problem of large aperture lenses. Its new design ensures superior peripheral brightness.

Comments about Sigma Sigma 18-50mm F2.8 EX DC Lens (Sigma Mount):

I am very pleased with this lens after breaking it in to take team photo. I relied on the len's wide angle capabilities more than i expected. The F/2.8 minimun aperture across the len's focal length range in combined with my D200 image stabilization to allow me to obtain many great low light shots that other wise would not have been possible. Focusing was always fast and accurate. All around great lens, Love it!!
