Sigma Press Release

A new zoom lens for the “KONICA MINOLTA” Digital SLR Camera System.

2005.11.14 - Sigma Corporation is pleased to announce the launch of the new 18-200mm F3.5-6.3 DC for KONICA MINOLTA mount. 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. Two Special Low Dispersion (SLD) glass elements and two hybrid aspherical lenses offer the utmost correction for all types of aberrations, and enables this extended range super zoom lens to be housed in a compact and lightweight construction of 70mm (2.8in) diameter, and 77.6mm (3.1in) in length, and weighing just 390g/13.8oz. The new lens coating reduces flare and ghost, which is a common problem of digital cameras and also creates an optimum color balance. This lens has a minimum focusing distance of 45cm (17.7in) at all focal lengths and has maximum magnification of 1:4.4.

The lens design incorporates an inner focusing system, which prevents the front of the lens from rotating, making it particularly suitable for using circular polarizing filters and petal shaped lens hoods. The overall length of the lens does not change during focusing, ensuring convenient handling and ease of use. A zoom lock switch eliminates “zoom creep” during transportation, a convenient addition when traveling.

* If KONICA MINOLTA ?-7 DIGITAL (Maxxum 7D / Dynax 7D) and ?Sweet DIGITAL (Maxxum 5D / Dynax 5D) cameras are used, the angle of view will be equal to 27-300mm focal length.
* Vignetting will occur if the lens is used with digital cameras with image sensors larger than APS-C size or 35mm SLR cameras.
