The Sigma 70-200mm f2.8 EX DG OS HSM lens is the second generation of the large aperture 70-200mm f2.8 telephoto zoom and now incorporates Optical Stabilisation (OS) which makes viewing a stabilized image in the viewfinder possible and helps achieve blur-free shots, even at maximum zoom. The lens has two FLD glass elements (with performance equal to fluorite glass) that have been added along with three SLD glass elements to provide correction of colour aberration, while Super Multi-Layer lens coating reduces flare and ghosting. Despite these additions, Sigma has managed to make the 70-200mm f2.8 EX DG OS HSM lens more compact than its predecessor. The fast f/2.8 aperture is extremely useful in low light or when shooting fast moving subjects where a higher shutter speed demands maximum light gathering. The HSM (Hyper Sonic Motor) offers quiet and high speed AF as well as full-time manual focus capability, ensuring the Sigma 70-200mm f2.8 EX DG OS HSM lens provides outstanding image quality and ease of use.

The Sigma 50-500mm f4.5-6.3 DG OS HSM lens is an upgrade to Sigma's popular 50-500mm ultra-telephoto zoom, and now includes an Optical Stabilizer which offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible - a particularly useful addition on a lens of this size. The Sigma 50-500mm OS lens incorporates HSM (Hyper Sonic Motor), to ensure quick and quiet auto-focus, as well as full-time manual focus capability. Four SLD (Special Low Dispersion) glass elements provide excellent correction of colour aberration, while the Super Multi-Layer Coating reduces flare and ghost and ensures high image quality throughout the entire zoom range. The addition of the optional 1.4x EX DG or 2x EX DG APO Tele Converters produce a 70-700mm F6.3-8 or a 100-1000mm F9-12.6 MF zoom lens respectively. The filter size of this lens is 95mm, but the lens is supplied with a step down ring enabling digital cameras with an APS-C size image sensor to use an 86mm filter.
