Comments: | Il y a trois versions de ce 500 mm catadioptrique. Ici, il s'agit de la seconde, de 1983. La première date de 1977 et l'objectif est gravé " RF ROKKOR-X ". La troisième ne comporte plus que " RF ", la mention " ROKKOR " à disparu, et elle date aussi de 1983. Des filtres en diamètre 39 mm étaient prévus, que l'on pouvait visser à l'arrière : jaune (Y52), Orange (O56), rouge (R60), et gris neutre X4 (ND 4x) pour compenser l'absence de diaphragme réglable. |

Under the Second Empire, it was fashionable between middle class people and nobles to exchange small cards with his photo, as it was customary to buy those representing personalities. The launch of this mode is attributed to Disderi. Here, everyone of you can add his own.
