I have recently purchased the Panasonic DC-FZ 1000 II. I am looking for a wireless remote shutter release to go with it. Most of the matching products are with an adapter that is mounted on the hot shoe of the camera and then connected WITH a cable to the shutter release. I would like a wireless remote trigger that is switched to remote trigger on the camera, like the Nikkon for example, and that's it. I can shoot from several metres away WITHOUT a cable! Is there anything suitable that is not ORIGINAL PANASONIC?
