The Lightning Strike! II Sensor Shutter Release for Select Canon Cameras from AEO Photo will help you capture that incredible photo of lightning you've been trying for without success. This shutter trigger mounts in your camera's hot shoe, with a dedicated cable to activate the shutter. It will detect a fast lightning event day or night, and trip the shutter in 0.1 ms (millisecond). A camera's added shutter lag time will vary.
This Lightning Strike includes a C-N3 cable for use with Canon cameras that have an N3 remote input (check your camera's owner's manual for compatibility). It has a low profile slide switch that won't activate in your camera bag--this prevents the battery being drained accidentally. A low profile LED minimizes reflections when shooting through a car windshield. This device operates on one 9V battery (included).
