Sigma Corporation has announced the launch of the new 50-500 F4-6.3 EX DG/HSM lens. This high zoom ratio lens is optimized for digital SLR cameras and capable of covering a wide range of focal lengths from 50mm standard to 500mm ultra telephoto. 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 ghost, which is a common problem of digital cameras and also creates an optimum color 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 HSM Hyper Sonic Motor models provide quiet high-speed AF function, as well as full-time manual focus capability., The rear focus mechanism produces a non-rotating front lens element which accepts a bayonet "Petal-type Hood", which prevents extraneous light from degrading the image quality. By adding an APO teleconverter (sold separately), you can use this lens as a 140-700mm f/7.3-8.8 MF ultra-telephoto zoom lens with a 1.4X EX teleconverter, or as a 200-1000mm F10.4-12.6 MF ultra-telephoto zoom lens with a 2X teleconverter. Teleconverters can be used in 100mm – 500mm focal length range.

This ultra-telephoto
zoom lens covers a telephoto range up to 500mm and allows photographers to bring
the subject close and short perspective. Sigma's original OS (Optical Stabilizer)
function offers the use of shutter speeds approximately 4 stops slower. It is
ideal for sports, wildlife and landscape photography with handheld shooting. Three
SLD (Special Low Dispersion) glass elements provide excellent correction for chromatic
aberration. This lens is equipped with a rear focus system that minimizes fluctuation
of aberration caused by focusing. The super multi-layer lens coating reduces flare
and ghosting. High image quality is assured throughout the entire zoom range.
This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed
AF as well as full-time manual focusing capability. The addition of the (optional)
1.4x EX DG APO or 2x EX DG APO Tele Converters produce a 210-700mm F7-9 MF ultra-telephoto
zoom lens or a 300-1000mm F10-13 MF ultra-telephoto zoom lens respectively. A
removable tripod socket (TS-31) is included as a standard component.

Sigma
has announced a large aperture, standard prime lens with claimed superior peripheral
brightness and corrected sagittal coma flare, ideal for all digital SLR cameras.
The lens is perfectly suited for a wide range of subjects enabling outstanding,
sharply defined images against a nicely blurred background. The fast, F1.4 aperture
makes this lens desirable for use with Digital SLR cameras; it effectively becomes
an 80mm medium telephoto lens on digital cameras with APS-C size image sensors.
The optimum optical design and molded glass aspherical lens elements provide
excellent correction for all types of aberrations. The super multi-layer lens
coating reduces flare and ghosting. Superior optical performance is also ensured
throughout the focusing range. This lens has a minimum focusing distance of
45cm (17.7") and has maximum magnification of 1:7.4. It creates a very
attractive blur, even when a small aperture is used. It incorporates HSM (Hyper
Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual
focus override.
