This Konica AR-1M electronic cable release is in good clean condition, and is compatible with the following Konica 35mm film cameras: FT-1, FS-1, FP-1, and FC-1. This is something I tested and used on an FC-1 in the past, but I cannot currently test the item since I no longer own a compatible camera. It's very likely to be working fine, but if not, I do accept returns. Thanks for looking.
