This latest version of the Sigma APO 120-300mm F2.8 EX DG OS HSM is pleased to announce the inclusion of Optical Stablization(OS) which is critical to equipment sporting this focal range allowing for hand-held tele-photography and the use of shutter speeds approximately 4 stops slower than would otherwise be possible. Sigma's new splash-proof feature is also included preventing dust and precipitation from getting inside the lens. One SLD and two FLD glass elements provides maximum correction of chromatic aberrations. The super multi-layer coating reduces flare and ghosting, and the lens design incorporates an inner focusing and inner zooming system to ensure sharp images throughout the entire zoom range. Improved optical performance provides excellent correction of sagittal coma flare and... Less

This lens replaces the previous high quality L-series 28-70mm f/2.8 lens, with a lens of even greater caliber. The range has been extended to cover an ultra-wide angle of 24mm, which makes it ideal for digital as well as film shooters, and the optics are even better than before with two Aspherical elements and a totally new UD glass element. It's now sealed and gasketed against dust and moisture, and a new processing unit makes the AF faster than ever. Internal Focusing The internal focusing mechanism allows the front of the lens to remain stationary and to easily accommodate specialty filters, such as polarizing filters. Two Aspherical Elements A lens design incorporating elements ground so the curve of the surface does not describe an arc of a circle. Especially useful... Less

Sigma's New APO 70-200mm F2.8 EX DG OS HSM is the second generation of this large aperture telephoto zoom lens now incorporating Sigma's Optical Stablization function, OS, Sigma's own anti-shake system. Two FLD glass elements, which have the performance equal to fluorite glass have also been added along with three SLD glass elements, all which provide excellent correction of color aberration. In spite of the additions of all of these features, Sigma has managed to make the lens more compact than its predecessor, measuring only 7.8" in length. For any serious photographer where the 70-200mm focal range is often the most important second lens to own after the initialstandards lens or mid range zooms. The fast aperture is extremely useful and important in low light environments or when... Less
