Sigma 17-50mm f/2.8 EX DC OS HSM 35mm Zoom 


The Sigma 17-50mm F2.8 EX DC OS HSM is a large aperture standard zoom lens designed for digital SLR cameras. It incorporates Sigma’s efficient Optical Stabilization (OS) function and is a compact lens with an overall length of just 3.6 inches. This lens covers a focal length from 17mm wide angle and offers a large aperture of F2.8 throughout the entire zoom range, making it ideal for many types of photography such as portraiture and landscapes. The OS function offers the use of shutter speeds approximately four stops slower than would otherwise be possible. For Sony and Pentax mount, the built-in OS function of this lens can be used even if the camera body is equipped with an image sensor shift anti-shake system. As compensation for camera shake is visible in the viewfinder, the photographer can easily check for accurate focus and ensure there is no subject movement. Two FLD glass elements, which have performance equal to fluorite glass, plus two glass mold and one hybrid aspherical lens, provide excellent correction for all types of aberrations. The Super Multi-Layer Coating reduces flare and ghost. This lens has superior peripheral brightness and provides sharp, high-contrast images even at the maximum apertures. High image quality is assured throughout the entire zoom range. Incorporating Hyper Sonic Motor (HSM), the lens provides fast and quiet auto focus. The lens has a minimum focusing distance of 11 inches throughout the entire zoom range and a maximum magnification ratio of 1:5. The rounded seven-blade diaphragm creates an attractive blur to the out of focus images. The inner focusing system eliminates front lens rotation, making the lens particularly suitable for use with the supplied petal-type lens hood and circular polarizing filters.

Piqué à toutes les focales et dès 2.8
Qualité de construction.
Livré complet avec pare soleil et housse
Compacité et poids.



Piqué superlatif pour ce sigma et surtout dès la pleine ouverture; le centre est exceptionnel, les angles très bons (il faut visionner à 100% pour distinguer la différence entre les angles et le centre). Avec un Canon 60D, les clichés à 2.8 en basse lumière sont étonnants de précision. La qualité de construction est excellente, très agréable au toucher. Livré avec un sac de transport et le pare-soleil inclus.
L'OS est extrèmement performant et totalement inaudible. HSM précis et très rapide.
Très bonne affaire que je recommande sans restriction.
