Abstract

L'invention concerne un système optique et un appareil photographique. Le système optique (10) comprend : un premier groupe de lentilles (1), un deuxième groupe de lentilles (2) et un troisième groupe de lentilles (3) qui sont agencés en séquence d'un côté objet à un côté image, le premier groupe de lentilles (1) et le deuxième groupe de lentilles (2) ayant tous deux une puissance focale positive et le troisième groupe de lentilles (3) ayant une puissance focale négative. Le système optique (10) est tel que: 0,85<|f1/f|<4,5; 0,5<|f2/f|<1,5; 3<|f3/f|<10; 1<|TL/f|<1,5; 0<|T1/T2|<0,5; 0<|T3/T2|<0,5; avec f, f1, f2 et f3 qui sont des longueurs focales et TL, T1, T2 et T3 qui sont des distances entre les groupes de lentilles, un diagramme et un plan d'imagerie.
