Vario Switar 36 f/1.9 (8mm-36mm)
Introduced in 1962 and designed by Kern for the H-8 reflex. It incorporated an automatic pre-set diaphragm feature which opened the diaphragm for viewing and focusing and closed it automatically prior to exposure. The pre-set aperture control and camera release mechanism were combined with a zoom lever; this could be couple to the Declic H grip with a special accessory cable (not shown). It could accept Series VI filters and weighed 13.5 ounces.
