IF (Inner Focus)
To ensure stability in focusing, this lens moves the inner lens group or groups without changing the lens' physical length.

ASP (Aspherical Lens)
The aspherical lens complex allows freedom of design, improved performance, a reduced number of component lenses and a compact size.

DC (DC Lens)
These are special lenses designed so that the image circle matches the smaller size of the image sensor of most digital SLR cameras. Their specialized design gives these lenses the ideal properties for digital cameras, the compact and lightweight construction is an added bonus ! including compact and lightweight construction.

18-125mm f/3.5-5.6 DC

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 use with digital Single-Lens Reflex (SLR) cameras 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.) in length and 70mm (2.8in.) in diameter, with a weight of 385gr (13.6oz.) and filter size of just 62mm.

Inner Focus System
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.
