Comunicato stampa :
The 50-150mm f2.8 S ED OIS Lens from Samsung features the NX mount and is a Premium "S" Series lens. It offers a 35mm-equivalent focal length range of 77-231mm, making it suitable for portraits as well as sports photography and wildlife. Regardless of the focal length selected along the lens barrel, an f/2.8 maximum aperture can be selected to benefit low-light shooting or provide shallow depth of field. For a wider depth of field or to compensate for high shutter speeds that may otherwise be needed under very bright shooting conditions, the lens can be stopped down to f/22.
Consisting of 20 elements in 13 groups, including four ED (extra-low dispersion) and one XHR (eXtreme High Refractive) element for excellent clarity, detail and sharpness, this 50-150mm also includes optical image stabilization. This feature helps prevent user movement from rendering an image unusable while handholding the lens and a compatible camera. An Ultra-Precise Stepping Motor (UPSM) improves upon the conventional Stepping Motor (SM), offering three times the precision in its ability to focus on subjects.
To make this lens particularly useful for sports, wildlife, and variety of subjects frequently recorded outdoors; Samsung has incorporated SHS (Samsung Hyper Shield) Coating that protects the front element from dust, water, fingerprints, and smears.

Ottica interessante, della stessa famiglia del 16-50mm f2-2.8 e finalmente Tropicalizzata. Samsung sembra star facendo davvero sul serio! Il prezzo mi sembra un pò alto però. |
