Pentax Cable Switch F This is a remote cable switch for Pentax AF film SLR cameras, including the SFX series, Z series, and MZ series. I purchased this new at the time, but I never used it and have been storing it. The outer box has been stored for a long time, so it is dirty, but as you can see, the main body is still intact, and the cable fastener is still in place. However, there may be some age-related deterioration, so I will sell it to someone who understands this.
