Sigma 50-500mm F4-6.3 EX DG/HSM featuring Triple-cam Rear Focusing System ensures high precision throughout the whole focus range, Uses four SLD (the special low dispersion) glass elements for superior optical performance, and HSM system ensures quiet and high-speed auto focusing
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.
- Most effective coating for minimizing flare and ghost with digital SLR cameras.
- Triple-cam Rear Focusing System ensures high precision throughout the whole focus range.
- Uses four SLD (the special low dispersion) glass elements for superior optical performance.
- Accepts both 1.4X and 2X APO EX Tele-Converters, the lens can be used as a 1000mm ultra-telephoto zoom lens.
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.
