The FC-1, first introduced in 1980, is practically an FS-1 without the built-in motor.
On the FC-1, an external motor can be attached, the Konica Auto Winder F. This motor is quite large and not very fast (about 1.5 frames/second). The Auto Winder F fits the FP-1, too. Like the FS-1, the FC-1 is a camera with electronically controlled shutter, too. It needs a battery for all functions, exposure is impossible without batteries with the FC-1. Read more hereForum
