LEICA SET TRI-ELMAR-M ASPH noir
Trois focales, haute performance, compacité: Deux éléments asphériques dans la formule optique de cet objectif garantissent des résultats parfaits. La mise au point interne améliore significativement la qualité d’image aux courtes distances de mise au point, en particulier grâce à l’intégration d’une lentille flottante. Avec la possibilité de choisir entre trois focales à partir d’un seul objectif, le Tri-Elmar-M offre aux photographes une flexibilité maximale.
