About Sigma 18-125mm

The Sigma 18-125mm F3.8-5.6 DC OS HSM is a high ratio zoom lens which is designed exclusively for digital SLR cameras

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 andhorizontal 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.

Good lens


from Lawrence, MI  -  Semi-pro Photographer

Good lens for travle. Depending on type of wild life good for that too. Very sharp, good auto focuse.


Ideal for every day use


from Belton, TX  -  Casual Photographer

I use this on my Pentax K10, lens is ideal for everyday use, especially indoors where sometimes you need a wide angle lens, and then go outside where you might need a long zoom lens. It is not weather resistant like the Pentax DA lenses are.


very good quality


from VA  -  Semi-pro Photographer

good for travel

Sigma lens


from Dawsonville, Ga.  -  Photo Enthusiast

I like this one almost better than the 70-300....but need it for the macro jobs


good travle lens


from MI  -  Semi-pro Photographer

This is a good lens to travel with because of it's zoom range. Super quite focus. It's also good as an event lens, like birthday party's, weddings etc. Seems a little heavy for the size.


great all purpose lens


from Hillsboro, Texas  -  Photo Enthusiast

Great as an all purpose lens. I like the markings on the lens, vivid, clear and easy to read.


Good lens but HEAVY


from Montreal, Qc  -  Semi-pro Photographer

I bought this lens used at Adorama.[...]. The lens is ok, but really HEAVY and just so/so image quality, especially at the edges. I would recommend it though.


Nice Lens at a Great Price


from southern Oregon  -  Photo Enthusiast

This lens is much better than the canon consumer lenses in my opinion. It may have a slight front focusing issue and if it does I'll send it back to sigma for an adjustment or use it as an excuse to upgrade to the 50D with micro adjustment instead of sending it back to the retailer so everyone else can take the time and expense of correcting a common problem with most lenses.

Joss M  Does this lens work on a Canon EOS-1D Mark II?
MIKE B  I honestly don't know. The lens was bought for a Canon XSi and seems to work just fine with that body.
