This compact high zoom ratio lens incorporates Sigma's original OS (Optical Stabilizer) function. This system uses two sensors inside the lens to detect vertical and horizontal movement of the camera and works by moving an optical image stabilizing lens group to effectively compensate for camera shake. It offers the use of shutter speeds approximately 4 stops slower.

It is the ideal lens for several type of photography such as wide-angle, telephoto and close-up. SLD (Special Low Dispersion) glass, a molded glass aspherical lens and two hybrid aspherical lenses provide excellent correction for all types of aberrations. The super multi-layer coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range.

This lens has a minimum focusing distance of 35cm (13.8") at all focal lengths, and has maximum magnification of 1:3.8, making it ideal for close-up photography. This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed autofocus.

I guess I got a good one.., June 4, 2009

There were several mixed reviews on this product but I went ahead and purchased it anyway. I was replasing a Canon 18-55 IS "kit" lense that I dropped. (which is a great lense. Don't be confused by the reviews of the older model 18-55 that's not an IS. The IS version is a fantastic starter lens.) I got my lens from 47th St. and received it today. I've taken 74 pictures so far and just now viewed them on my computer. Awesome! I love the color and crispness of them. I'm not even close to a professional photographer. I use my XSI to take pictures of my 16 month old son and that's it so take my recommendation for what it's worth. It seems to me though that if you get a good "copy" you will be extremely pleased. My thought was if I wasn't happy with the quality I would just keep returning them until I got a good one. Maybe I'm just lucky but I got a great copy the first time around.

This is a new lens from Sigma. I could not find any detailed reviews on the net before I bought it. It's a well built amateur lens with a nice focal length coverage that's not available from Canon. It's significantly heavier than Canon's 18-55mm plastic kit lens, likely due to more metal and glass used in construction. The focus is reasonably fast compared to Canon's kit lens and slightly quieter. For those who are familiar with Canon's ring type USM lenses, however, the this HSM lens is not a ring type HSM. This means it's not as quiet or as fast as the true ring-USM. And it does not allow "full-time manual focus". You have to turn AF switch off to manually focus the lens. This was a little disappointment for me for a lens at its price range. Sigma could have used a ring type HSM. Another thing I noticed is that while the OS (optical stabilizer) can be switched on or off, the OS gyroscope seems to be powered on even when the OS is off. You can hear the little noise from the piezoelectric gyro. My concern is that it can still drain battery power when OS is off. Optically, I am not in a position to say much because I have a 8MP camera. It's certainly adequate for me. Overall, I am happy with it and sold the kit lens that came with my camera.

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 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.
