Jintu WFC-07 Wireless / Wired Timer Remote Shutter Release Intervalometer for select PENTAX and Canon cameras

Has 2.5mm sub-mini connector (check your camera)

You may use this as a wired remote (plug cable into hand control unit) or use the wireless remote unit.

This may also work on other cameras but I don't know which brands it will support.

This item is used but it is hard to tell as it is in very good condition.  The battery door does not hold closed so it will have to be held closed with a piece of tape.
