Introduction

The Sigma Corporation is pleased to announce the launch of the new 28-200mm F3.5-5.6 DG Macro lens. This compact, high-zoom ratio lens is designed to suit the special characteristics of digital cameras. The new multi-layer lens coating and lens design reduces flare and ghosting, and creates an optimum color balance throughout the entire zoom range. Two aspherical lenses ensure excellent correction for all types of aberration. The lens displays a high level of optical ability throughout the entire zoom range for digital and film SLR cameras. This lens has a minimum focusing distance of 48cm (18.8?) throughout the entire zoom range.

Zoom & Lens hood
At the 200mm telephoto setting, the lens is capable of close up photography with a 1:3.8 maximum magnification. A zoom lock mechanism is provided to prevent the lens from creeping due to gravity. Since the front of the lens does not rotate during focusing, a circular polarizing filter and ?Petal-type hood? can be easily attached and used.
