Sigma have announced the launch of the several new lenses.

The 18-125mm F3.5-5.6 DC.
Sigma announce three new lensesThis zoom lens was exclusively designed for use with digital SLRs with the popular APS-C sensor. This latest lens from Sigma`s DC range has a 6.9 times magnification zoom ratio. The image circle is designed to match the size of the image sensor of digital SLR cameras resulting in a surprisingly compact and lightweight superzoom lens.
A Special Low Dispersion (SLD) lens and two aspherical glass elements produce a high level of optical performance through the entire zoom range.
This lens has a minimum focusing distance of 50cm (19.6") at all focal lengths and is equipped with an inner focusing system. The non - rotating front element makes the lens particularly suitable for using the petal-shaped lens hood (supplied) and circular polarizing filters. The lens is equipped with a zoom lock which eliminates "Zoom Creep".

* Vignetting will occur if the lens is used with digital cameras with image sensors larger than APS-C size or 35mm SLR cameras.

This zoom lens was exclusively designed to suit the characteristics of digital SLR cameras with APS-C type sensors. The image circle was designed to match the size of the image sensors of digital SLR cameras, resulting in a compact and lightweight construction. The use of aspherical lenses provides correction for various aberrations throughout the entire zoom range and produces high level of optical performance. 18-50mm F3.5-5.6 DC lens has a minimum focusing distance of 25cm (9.8") at all focal lengths and is capable of macro photography with a maximum magnification ratio of 1:3.5.
