While offering sophisticated optical performance and expressiveness, this Sports line lens delivers high action-capture performance to meet the needs of the most demanding professional photographers, enabling them to get exactly the shots they want – they can capture fast-moving objects even at a distance - two FLD (performance equal to fluorite glass) glass elements and one Special Low Dispersion (SLD) provide excellent correction of color aberration.
Dust proof and splash proof features have been incorporated into joint parts including mount attachment, manual focus ring, zoom ring, customization switches and external switch panels, to insure excellent durability under even the most extreme situations.
Equipped with Sigma’s unique Optical Stabilizer Technology – the OS function offers the use of shutter speeds up to 4 stops lower than would otherwise be possible.
Another major feature of this Sports line lens is the wide range of customization functions available using the software provided and newly developed USB DOCK (optional).
The incorporation of Sigma’s Hyper Sonic Motor (HSM) provides quiet, high speed and accurate auto-focusing as well as full time manual focus capability – incorporation of a focus limiter offers adjustable range focusing to provide fast focus setting.
An inner focusing and inner zooming system ensure sharp images throughout the entire zoom range.
Improved optical performance provides excellent correction of sagittal coma flare to produce ultra-high resolution images, comparable to a fixed focal length lens.
