The 1967 Konica Auto S1.6 is - for all practical purposes - the last of the Auto S series and an update the earlier Auto S2 offering a 1/3-stop faster f/1.6 lens. Sure, there is the Auto S3 model that will be offered in following years, but that model really has little in common with the Auto S1.6. The Auto S3 is actually the top-of-the-line model within the compact C35 series. The home-market version in Japan was named "C35 FD", instead of Auto S3. The Auto S1.6 is fitted with a more complex 45mm f/1.6 Hexanon lens (7 elements, 5 groups), in a Copal SVA leaf shutter that provides 1s-1/500s & B. The lens has a built-in, pull-out shade and accepts 55mm filters. Working 100 % in Good Condition and i sell the way it is. " COLLECTIBLE, AND DECORATIVE " Well protected and tracking number.
