18-125mm F3.5-5.6 DC DC Lens for Digital SLR Camera

Sigma Corporation of America

Super Multi Coating reduces flare and ghosting that tends to occur when using digital SLR cameras.

Specially designed to suit the characteristics of digital SLR cameras, this compact and lightweight lens is now a reality.

This zoom lens was exclusively designed for digital SLR cameras featuring APS-C size image sensor and has a 6.9:1 zoom ratio. The image circle is designed to match the size of the image sensor of digital SLR cameras.
From wide angle to telephoto, this new zoom lens can capture a wide range of subjects. As there is no need to change lenses, there is no risk of missing those great shots. This lens has a minimum focusing distance of 50cm (19.6in.) at all focal lengths and a maximum magnification of 1:5.3. A distance scale on the focus ring makes the lens convenient and easy to use.

A lens specially designed to suit the characteristics of digital cameras is now a reality.

Sigma’s vast experience has been gained over many years in the development of advanced optical technology and film camera production. This experience was crucial to the development of the SD9 and SD10 digital SLR cameras. Sigma took digital characteristics into consideration when designing the lens power layout and created the most suitable lens.
A Special Low Dispersion (SLD) lens and two aspherical glass elements produce a high level of optical performance through the entire zoom range.
We used the most appropriate coating for digital products to reduce flare and ghost, caused by digital SLR cameras and to produce the best color balance.

The advanced design has resulted in a compact and lightweight lens.

A Special Low Dispersion (SLD) lens and two aspherical glass elements produce a high level of optical performance throughout the entire zoom range. The resulting design has produced a compact and lightweight lens measuring just 77.7mm (3.1in.), maximum diameter by 70mm (2.8in.) in length, with a weight of 385gr (13.6oz.) and filter size of just 62mm!

Inner Focus

The lens is equipped with an inner focusing system, which prevents the front element from rotating making it particularly suitable for Petal shaped `hoods and a circular polarizing filters.

Zoom Lock

The lens is also equipped with a zoom lock that eliminates "zoom creep" during transit.
