Sigma 50mm f/1.4

18 mars 2008 par Pascale Dechamps

Sigma annonce un objectif 50mm f/1.4. pour reflex Sigma, Canon, Nikon, Pentax et Sony. Cet objectif est pourvu d'un moteur hypersonique pour un auto-focus silencieux et rapide.

Ca fait plaisir de retrouver cette focale classique (qui devient un petit télé, idéal pour le portrait, surtout avec la grande ouverture sur capteur APS-C) doté d'une motorisation rapide. A voir la qualité optique mais, à priori, ce ne sont pas des objectifs très difficiles à réussir.

50mm F1.4 EX DG HSM

The Sigma Corporation is pleased to announce the new large aperture 50mm F1.4 EX DG HSM standard lens. For Sigma, Canon, Nikon, Pentax* and Sony*

• Standard lens with large maximum aperture of F1.4.
• It creates sharp images with high contrast and ensures superior peripheral brightness.
• Incorporates molded glass aspherical lens, perfectly correcting coma aberration and creating superior image quality.
• Super multi-layer coating reduces flare and ghosting.
• Hyper Sonic Motor (HSM) ensuring silent, high-speed AF

This is a large aperture prime lens with a standard focal length of 50mm, ideal for digital cameras. This lens is perfectly suited for a wide range of subjects enabling outstanding, sharply defined images against a nicely blurred background. The fast, F1.4 aperture makes this lens desirable for use with Digital SLR cameras. This lens effectively becomes an 80mm medium telephoto lens on digital cameras with APS-C size image sensors. The optimum optical design and molded glass aspherical lens elements provide excellent correction for all types of aberrations. This lens has superior peripheral brightness and provides sharp, high contrast images even at the maximum aperture. Superior optical performance is also ensured throughout the focusing range. The super multi-layer lens coating reduces flare and ghosting. This lens has a minimum focusing distance of 45cm (17.7”) and has maximum magnification of 1:7.4. It creates a very attractive blur, even when a small aperture is used.

This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as
well as full-time manual focus override.

* If the camera body does not support HSM motor, AF does not work.
