Designed for APS-C digital SLR, the new lens launched today by Sigma, the Sigma APO 50-150mm F2.8 EX DC OS HSM, will be available for Canon and Nikon cameras and will offer to the 50-150mm lens Sigma’s optical stabilisation system for an advertised 4EV blur compensation.Sigma has placed the finest technology they have in stock on this new lens like HSM drive, OS, SLD glass… Here are the Sigma APO 50-150mm F2.8 EX DC OS HSM bullet points :
- 50-150mm focal length for APS-C cameras
- Canon and Nikon mount
- F/2.8 on the entire range
- 21 elements in 15 groups
- 9 circular aperture blades
- 6 SLD glass elements (a new type of glass launched by Sigma at the PMA 2010, a glass said to have fluorite-like properties for a fraction the price of the optically talented but freaking expensive fluorite Canon use on some L lenses).
- OS : optical image stabilisation
- EX build quality
- HSM : ultrasonic autofocus motorization
- 80cm minimum focusing distance (max magnification ratio 1:6.3)
- Filter size : 77mm
Its price is rather faire for such a lens. It should come to the market at a pretty interesting $1099 pricetag.
I don’t see the Sigma APO 50-150mm F2.8 EX DC OS HSM coming out in Sony A-mount as Sony DSLRs have CCD-shift stabilization.
