SUMMARY
The Konica C35 AF, launched in 1977, is recognized as the first mass-produced camera to feature autofocus. This innovation aimed to solve the common problem of out-of-focus photographs, which accounted for 36% of ruined amateur snapshots. The camera utilized Honeywell's passive Visitronic module, which measured distance from the camera's top plate, independent of the taking lens. This system allowed the camera to automatically adjust focus, selling approximately one million units in two years and leading to November 30 being observed as Camera Day in Japan.
