Skrevet af Noel Christensen i Objektiver, Review

dpreview.com har anmeldt Sigma 18-250mm f/3.5-6.3 DC OS HSM, et nyt superzoom objektiv der udvider Sigma’s sortiment der tildligere har “toppet” med Deres 18-200mm.

dpreview.com skriver bl.a.:
The Sigma 18-250mm f/3.5-6.3 DC OS HSM was first announced in January 2009, becoming available to buy in March the same year. It’s essentially an update to the 18-200mm f/3.5-6.3 DC OS HSM, with an extended 13.9x zoom range bringing it closer in reach to the 18-270mm F3.5-6.3 VC from Sigma’s great rivals Tamron. Impressively, the improved telephoto range has been accommodated with scarcely no change in size (Sigma’s specifications note a mere 1mm growth in length), and only a modest increase in weight. A notable change though is the addition of Pentax and Sony to the list of supported mounts (alongside Canon, Nikon and Sigma), giving owners of these systems the opportunity to choose between Sigma’s in-lens Optical Stabilization (OS) technology and their camera’s in-body systems. All versions also use an in-lens HyperSonic Motor (HSM) for focusing; however Pentax owners should note that this won’t work on bodies older than the K10D of 2006, which don’t support SDM focus motors.
