This JJC MA-D Wired Remote is a reasonably priced replacement for the Panasonic DMW-RS1 remote control. The MA-D is equipped with a two-step shutter release button. If you press the button halfway, the camera will focus, if you press the button all the way, the picture will be taken. You can also lock the shutter button to make use of long exposure times or for continuous shooting.
