f/3.5 pour ce genre de format était un objectif très lumineux.Oui, F3,5 était l'ouverture habituelle des 6x6 et 6x9.
Les 6x6 et les 6x9 étaient le plus souvent des tirés par contact.
Je me souviens que le 6x6 Rolleiflex 80 / F2,8 avait la réputation de piquer moins que le 75 / F3,5.
Je crois que F2,8 a été l'ouverture maximum des objectifs "normaux" des 6x6 de la grande époque (Hasselblad, Zenza Bronica...).
C'est fini tout ça. Sniff.
