Sony Alpha 700 : 12 Mpx, stabilisation mécanique, 1400 euros
Le Sony Alpha 700 fait donc suite au Canon EOS 40D et le Nikon D300 dans la catégorie reflex expert.
Beaucoup de rumeurs ont circulé sur Internet, mais finalement le secret a été bien préservé. Voici donc officiellement le Sony Alpha 700. Une numérotation qui demandera quelques explications.
Parmis les nouveautés, on retiendra également
- le nouveau système de stabilisation (gain 4 vitesses)
- la touche ISO sur le dessus de l'appareil permet de modifier rapidement la sensibilité (celle-ci est indiqué dans le viseur)
- la présence de 3 modes programmables
Le Sony Alpha 700 sera sans doute proposé en kit avec de nouveaux objectfs dont le 16-105 mm présenté sur les visuels.
