The Sigma Corporation is pleased to announce the new 50-500mm F4-6.3 EX DG HSM for the Four Thirds fitting. This high zoom ratio lens is optimised for digital SLR cameras and capable of covering a wide range of focal lengths from 50mm standard to 500mm ultra telephoto. When used on a Four Thirds camera, the effective focal length will be 100-1000mm. This ultra-zoom lens employs a seven-group zoom system, which provides a high zoom magnification of 10x. Triple-cam Rear Focusing System ensures high precision throughout the whole focus range. The new lens coating reduces flare and ghosting, is a common problem of digital cameras, and also creates an optimum colour balance. This lens uses four pieces of SLD (the special low dispersion) glass for excellent correction of color aberration. A zoom lock switch eliminates zoom creep during transportation, a convenient addition when traveling. The rear focus mechanism produces a non-rotating front lens element which accepts a bayonet petal shaped hood, included, which prevents extraneous light from degrading the image quality.
