The Strike Finder Camera Trigger for Select Canon Cameras from Ubertronix is designed to photograph lightning strikes in day and night. It can also trigger your camera in response to other large light bursts such as fireworks. An infrared sensor detects light bursts and signals your camera in 45-60 milliseconds to release its shutter. The Strike Finder attaches to your camera's hot shoe and connects via a dedicated cable to its remote port. Once it has been turned on and set, it can be left in a safe and dry location to shoot automatically.
When shooting lightning, it is best to set the lens to Manual Focus and the camera to either Shutter or Aperture Priority mode. Do not use the Auto Mode. ISO should be set between 200-400.
The Strike Finder with the RS80N3 cable is compatible with the following cameras: Canon 1D Mark II, 1Ds Mark II, 1Ds Mark III, 5D, 5D Mark II, 5D Mark III, 7D, 10D, 20D, 30D, 40D, 50D, and other cameras compatible with the TC-80N3 (3-pin connector) shutter remote.
