Manufacturer's Description
This compact high zoom ratio lens is designed exclusively for digital SLR cameras and incorporates Sigma’s original OS 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 equivalent of using a shutter speed approximately 4 stops faster. SLD glass and aspherical lens elements enable this extended range zoom lens to be housed in a compact and lightweight construction and offers high image quality throughout the entire zoom range. The new lens coatings reduce flare and ghosting. The minimum focusing distance of 35cm throughout the entire zoom range allows a maximum reproduction ratio of up to 1:3.8. It also has an inner focusing system so it accepts the, included, Petal-type lens hood as well as circular polarising filters

The best All-around lens!
I've had the previous non-hsm and non-os version of 18-125.

This version has the following changes.
1) quite heavier (still very light though)
2) studier build
3) HSM, no more grrrrr-noise when focusing. Focusing is much faster
4) OS. Maybe the biggest pros. aprox 2-3 stops advantage. I can use it hand held at 125mm @ 1/30-1/50 and still get usuable shoots.
5) bigger front element 62mm vs 67mm. Considering that the front element is quite bigger and the lens is somewhat darket (f3.8vs f3.5) this means that there have been some major redesigns in the optic of the lens.

This lens is very good optically, much better than the previous, and it is usuable throughout all ranges and apertures (previous lens was quite soft at 125mm). Imho it is much better than other all-around lens such us 18-200 or 18-250, because the optical quality compromise is minimal. You might not have 200mm zoom, but it gives you a great quality for the range and the cost.

Considering the cost and the range 5/5 stars.
