The Konica C35 EF is a compact camera. It had the nickname "Pikkari" in Japan. Introduced in 1975, the Pikkari was the first 35mm compact camera with a built-in flash. The C in the name stands for "compact", the 35 for 35mm film, and the EF for "electronic flash". Focusing is enabled by selecting preset distances on the rotating lens barrel, using the zone focus method. It was superseded by the fixed focus Konica C35 EFP and autofocus Konica C35 AF.
