RR-100 Remote Release
This remote shutter release has a φ2.5mm jack. Similarly to the camera’s shutter release button, pressing the button halfway focuses on a subject, and pressing it all the way down takes a picture. In the BULB or continuous shooting mode, you can slide the shutter button to lock it. It is packaged with a right angle adapter for ease of storage and to prevent unintended cable dislodgment.
