Review summary from DPReview
This isn't a lens for pixel-peepers who above all else demand critical corner-to-corner sharpness in every shot. But for more normal users looking for a versatile, all-in-one travel lens within a budget, and who'd prefer to while away their evenings looking at and sharing their images rather than post-processing them, it fits the bill just fine.
Scoring is relative only to the other products in the same category.

Sample images for Sigma 18-200mm F3.5-6.3 DC OS HSM
- Sigma’s own unique technology OS (Optical Stabilizer) function
The 18-200mm f3.5-6.3 OS is equipped with Sigma’s own unique OS (Optical Stabilizer) technology. This system uses two sensors inside the lens to detect vertical and horizontal movement of the camera by moving an optical image stabilizing lens group, to effectively compensate for camera shake. It also automatically detects panning movement of the camera and compensate for camera shake when shooting moving subjects such as motor sports.
- Excellent Optical Performance
A Special Low Dispersion (SLD) lens and three aspherical glass elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range. The super multi-layer lens coating reduces flare and ghosting while producing the best color balance.
- Enables close-up photography
This lens has a minimum focusing distance of 45cm through entire zoom range with a maximum magnification of 1:3.9 making it very convenient for taking close-up pictures.
- Inner focusing system
Because the front of the lens does not rotate, circular polarizing filters and a petal-type hood can easily be used.
- Magnification scale
A magnification scale is displayed on the lens barrel, ensuring ease of use.
- Zoom lock switch mechanism
A zoom lock switch mechanism is provided to prevent the lens from creeping due to its own weight.
The lens design incorporates an inner focusing system that prevents the front of the lens from rotating, making it particularly suitable for using circular polarizing filters and petal-shaped lens hoods. In addition, the overall length of the lens never changes during focusing, making the lens convenient to handle and easy to use. Finally, the lens's zoom lock switch eliminates "zoom creep" during transport--a convenient addition when traveling. The lens, which includes a metal mount, is backed by a one-year warranty.

The good news which I really didn't expect was to see both lenses produce images that were nearly identical-- I thought for sure Canon's optics would far surpass Sigma's. Color saturation, light exposure through the lens, and detail were indistinguishable. The autofocus worked equally well on both. Both weighed about the same and were about the same size. The Sigma has a 72mm diameter aperture which I liked (so does the Canon). Of course the Sigma is 18-200, and at this time Canon does not have a competing option in the same digital SLR lens class with image stabilization.
The only aspect of the Sigma that differed significantly from Canon's lens was the noise of Sigma's autofocus motor. Sigma produces noticeable motor noise, though it wasn't overly loud. Still if you were shooting in a spot where silence was critical such as a ceremony, it may become an issue but probably not. In comparison, the Canon autofocus motor is silent and fast every time.
Sigma places a locking mechanism on the lens barrel to eliminate any possibility of lens creep (lens extending when pointed down). I doubt this would be a problem with the Sigma anyway. The zoom ring is a little stiff, but not too stiff. The manual focus ring is designed to be used with AF set to off to avoid manipulating the motor when focusing.
The image stabilization works well allowing you to shoot lower light photos without a tripod.Read more ›
Both lenses auto-focus accurately (no front or back focus) although the Sigma is slower to lock focus in low light and is a little noisier in getting there. Their IS/OS are equally effective at about 3 stops of compensation. Build quality, size and weight are about the same and both use the same 72mm filter size. Sigma includes a lens hood while Canon wants to sell you one.
In summary, the Canon is slightly better for me due to the faster and quieter low-light focus and improved telephoto image quality. The trade-off is poorer image quality than the Sigma for wide angle shots, even after stopping down. Finally, the Sigma lens costs about $200 less than the Canon at this time.
The OS worked great too, reducing blur in handheld situations up to 3 stops for me, maybe more for someone who can hold steadier than I can.
My wife LOVES the lens, since her shooting patterns entail her shooting at wide angles (landscapes) and then she may suddenly switch to shooting at moderate to high zoom (abstract images of objects etc), and then back again.
Before this lens, she would have to constantly switch from her 18-55 kit lens to her Canon 70-300 IS USM lens and back again, or just miss the shot because it wasn't practical to switch at the time.
The Sigma changed that. Now her kit lens is practically obsolete, since this lens has the 18-55 focal range, AND it has optical stabilization, which her kit lens doesn't.
Some of the reviews of this lens mention aberrations, pin cushioning and light falloff at extreme focal ranges, but we saw no signs of that. In fact, the images at 18mm on this lens appeared sharper and brighter than with the Canon kit lens.
As a serious hobbyist, she couldn't be happier with the lens.
However, after using the lens for a couple weeks, she began getting an occasional "Err99" message on her camera. We isolated it to the lens, since she had 4 other lenses - the 2 Canons and 2 Sigmas (a 55-200mm and a 10-20mm), and in the 15 months she owned her camera, she never got that error with any of the other lenses.
I wrote Sigma about it and they were very apologetic and helpful.Read more ›
