Sigma Lenses

Digital Camera Lens
18-200mm f/3.5-6.3 DC OS

11.1x high zoom ratio lens designed exclusively for digital SLR cameras and incorporating Sigma’s original OS (Optical Stabiliser) function.

Sigma’s unique OS (Optical Stabiliser) technology
This lens is equipped with Sigma’s own OS function. This function uses two sensors inside the lens to detect vertical and horizontal movement of the camera and works by moving an optical image stabilising lens group to effectively compensate for camera shake. It also automatically detects movement of the camera and compensates 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. It also produces an optimum, neutral colour balance.

Close-up photography
This lens has a minimum focusing distance of 45cm (17.7”) throughout the entire zoom range and a maximum magnification of 1:5.3, making it very convenient for taking close-up pictures.

Inner focusing system
An inner focusing system provides high performance and convenience. The non-rotating lens barrel perfectly suits the matched petal-type lens hood (supplied) and circular polarising filters.

Zoom lock switch mechanism
A zoom lock switch mechanism is provided to prevent the lens from creeping due to its own weight.

Digital Camera Lens
18-200mm f/3.5-6.3 DC

This high zoom ratio lens is exclusively designed for digital SLR cameras and capable of covering a wide range of focal lengths from wide-angle to telephoto.


SLD an Aspherical lenses
Two Special Low Dispersion (SLD) glass elements and two hybrid aspherical lenses offer the utmost correction for distortion and all types of aberrations.

Multi Layer Lens Coating
This lens uses a special coating which reduces flare and ghosting, a common problem with digital cameras and also creates an optimum colour balance.

Compact and Lightweight Design
This extended range super zoom lens is housed in a compact and lightweight construction of 70mm in diameter and 78.1mm in length, and weighing just 405g.

Minimum Focusing Distance of 45cm
This lens has a minimum focusing distance of 45cm at all focal lengths and has maximum magnification of 1:4.4.

Inner Focus
The lens design incorporates an inner focusing system, which prevents the front of the lens from rotating, making it particularly suitable for using circular polarising filters and petal shaped lens hoods. The overall length of the lens does not change during focusing, ensuring convenient handling and ease of use.

Zoom Lock
A zoom lock switch eliminates ‘zoom creep’ during transportation, a convenient addition when traveling.
