Sigma Announces New 18-200mm, F3.5-6.3 DC OS Lens for DSLRs



The 11.1 high zoom ratio lens is designed exclusively for digital SLR cameras and incorporates Sigma's original OS (Optical Stabilizer) technology. The MSRP is $820.00.

The hig- ratio zoom lens is incorporated with Sigma’s original OS (Optical Stabilizer) function and exclusively designed for digital SLR cameras. It is perfectly suitable for low light conditions, indoors, at dusk and telephoto range. 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. The inner focusing system is suitable for using a petal-type lens hood supplied and also circular polarizing filters.

Sigma’s own unique technology OS (Optical Stabilizer) function The 18-200mm f3.5-5.6 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 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 1:5.3 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 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.

Corresponding AF Mounts

This lens is available for Canon, Nikon and Sigma mounts. Canon mount is available now, Nikon and Sigma will be available in the near future.
