Hi all, I've got a Nikon D7100 and am interested in a remote (radio) shutter release for it. I've found "Pocketwizard" on the net but have seen some bad reviews of their reliability (albeit from a video several years old). What are people using out there? I need to be about 5 to 10 metres away from the camera and would definitely wan to go Radio and not IR if possible .. all suggestions welcome
