18-125mm F3.5-5.6 DC
Sigma Corporation is pleased to announce the launch of the new 18-125mm F3.5-5.6 DC.
This zoom lens was exclusively designed for use with digital Single-Lens Reflex (SLR) cameras and has 6.9 times high magnification zoom ratio. Image circle is designed to match the size of the image sensor of digital SLR cameras.
A Special Low Dispersion (SLD) and two pieces of aspherical glass elements produce high level of optical performance through the entire zoom range and also this has resulted in a compact, lightweight lens.
This lens has a minimum focusing distance of 50cm (19.6in.) at all focal lengths and equipped with inner focusing system. Since the front of the lens does not rotate, “Petal-type hood” and a circular polarizing filter can be easily attached and used. This lens is also equipped with Zoom Lock Switch that eliminates “Zoom Creep”.
* An image sensor element larger than those corresponding to APS-C cannot be used in digital cameras or 35mm SLR cameras. If such an element is used vignetting will occur on the picture surface.

The quality of responsiveness and range of versatility from this lens takes most other lenses out of serious consideration.
It is both lightweight and durable. It is quick to focus and quick on continuous shooting mode. There are no more hassles about the lense ring locking and staying in place (bye-bye Tokina...) The pictures out of this lense are full tonal under all lighting conditions. You'd be hard-pressed to know the flash was being used most times. No barreling from the hood. You get all the power of an effective-range 200+mm zoom and all the flexibility of an 18mm wide angle.
Put this lense on a Fuji S2 and compare it to pictures taken on an EOS Rebel and the Rebel is a has-been from the get-go.
I have never been happier with any lens than with this one. $269.99 was a steal for what you get from this product. I started shooting SLRs for the City of Los Angeles using SIGMA lenses and I'm a huge fan.
