Sigma 18 200mm f 3 5 6 3 DC AF OS Optical Stabilizer Zoom Lens for Canon Digital SLR Cameras

The Sigma 18-200 F3.5-6.3 DC OS HSM Lens incorporates an Optical Stabilizer function and is exclusively designed for digital SLR cameras. It is perfectly suitable for low light conditions whether indoors, at dusk, or in telephoto range. 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 compensates for camera shake when shooting moving subjects such as motor sports. SLD (Special Low Dispersion) glass and aspherical glass provide excellent correction for all types of aberrations. This lens has a minimum focusing distance of 45cm (17.7″) throughout the entire zoom range and has a maximum magnification of 1:3.9. Since the inner focusing system means the front of the lens does not rotate, optional circular polarizing filters and the supplied petal-type hood can easily be used. A magnification scale is displayed on the lens barrel, ensuring ease of use. A zoom-lock switch mechanism is provided to prevent the lens from creeping due to its own weight. 69.3 – 7.1 degrees (Sigma SD format) angle of view 7 Diaphragm Blades F22 Minimum Aperture 45cm / 17.7 Minimum Focusing Distance 1 – 3.9 Maximum Magnification Petal Lens Hood Dimensions – Diameter 79mm x Length 100mm Weight – 21.5 ounces (610 grams)

User Ratings and Reviews

2 Stars Great lens… for the short time it lasted
Loved this lens when it worked… however now, only one year later, this lens doesn’t work! Short circuits new Nikon D90 camera and won’t AF on D50. I can’t afford to be buying a new $500 lens on a yearly basis – I’m extremely disappointed in Sigma’s longevity.

3 Stars Good price and quality. Soft focus.
This is an universal lens. When you put in your camera you don’t feel to change it.

Pros:

1. Tele zoom. You can catch people without being noticed.

2. Wide angle. You can take photo of your large family and firends.

3. Decent quality.

Cons:

1. Soft focus. When you take photo at full zoom the soft focus is mostly unavoidable.

2. There is defocus to the corner of the lens.

3. Heavy.

4 Stars Great lens for the money
I bought this lens for my son’s wrestling tournaments and was not disappointed. Even indoors without a flash it was fast enough for great shots when they weren’t moving too fast. Reviews said the Canon and Tamron superzooms have better IQ, but they cost $200 more, and I wasn’t ready to spend that.

I’m keeping the lens on the camera more and more, only changing for my 50mm 1.4 for portraits or when I need the best IQ.

For a single walkaround lens, for the money, I don’t think it can be beat.

4 Stars wonderful lens
I received the len which was packed carfully. The len itself is very beautiful and the picture is beautiful too.

4 Stars Pretty good lens for the $.
This lens works pretty good with my Nikon D40 and I have made great shots using it.

After about a year of use I got no complaints and would buy it again in a heart beat.

Note: there is some lens creep but not terrible, the the OS makes an audible chirp sound and the auto-focus motor makes a very high pitched sound that’s a audible too (not as much as the OS tho), but it’s not that bad and I can easily live with this.
