Thanks. I was hoping to avoid the expense of wireless, but it sounds like it would really be the way to go. Does your unit fire and fire again and fire again, thus firing a series of single shots or does it use the camera's Continuous mode and apply a steady fire signal to the camera. (Or does it, in the single shot mode, just fire a pulse, no matter how long the button is held). I would expect that if it applied a steady fire signal as long as the button is held, the camera's Continuous mode would work the same as when I hold the button on the Nikon wired remote.
