Remote Control for the D7 using modified CDROM Audio Cable connector, two mini SPST monentary pushbutton switches form Radio Shack and a small bottle I found in the recycle bin. Use the white connector shown on the left. Had to grind down a pin socket on one side, both top and bottom and also grind a groove to fit the key in the D7 camera connection. I use the top button with my thumb to focus and the trigger finger to release the shutter.
