Any suggestions for a lightning strike shutter release device for the Canon 5DII? Reliability, cost, etc.

Any input would be greatly appreciated. Thanks

I have never heard of one, and can't imagine how something could see the light and then trigger the camera in time to capture the light. But there is an easy way to do it. Set up a time lapse trigger ( either shoot tethered or get a timer)
Set your camera on a tripod and set it to manual with a 30 second exposure with a big card in the camera, and set it and walk away. 270 raw images on a 8 gig card over a period of over 2 hours. a 32 gig card will go all night. The only tricky part is deciding which direction to point your camera.

I can assure you there are plenty around, like this for example:

That's true for the relatively instantaneous CG (cloud-to-ground) lightnings, but even CG strikes can last a few seconds, and there are other types that roll on for a considerable length of time. A lot fo the time, even with the "sudden" CG strikes, they cluster over a definable burst. A lightning trigger is a good thing, it works with less delay than a "human trigger" on a cable release :-) You can, of course, set the length of time to bulb for in advance.

What I really wanna do is take daylight landscape lightening photography... that is soooo cool!!

Maybe start by spelling "lightning" correctly? It's beginning to bug me... Lightening is what you do when you add bleach...

Spelling is not my game... imagery is. I'm a wild-eyed artist, not an English teacher. lol!!! ;)

Just enter "lightning trigger" at the B&H website for 61 options.
11/20/2013 06:40:56 PM · #9
Though "lightening trigger" will return 0 options ;)

Dang, Steve, Don't you have an advanced degree in the sciences?? ;-)

Oh, and by the way, good to see you posting!

You can relax now ... :-)

I wouldn't mind seeing some genuine feedback from photographers here that have used a lightning detector as the OP asked about. Have considered the purchase of one also.

I've seen some advertised that are supposed to sense the pre-lightning atmospheric change. ???

FWIW I saw a NOVA program last night on the "sprites" which result from large lightning discharges some amazing high-speed video shot from airplanes flying above the cloud layer. Should be available from streaming from the PBS website ...

You can use Magic Lantern as a lightning detector.

At first I scratched my head a little at this, then realized that yes, ML's feature to fire on exposure change can do that. But it will be relatively slow to react. A dedicated trigger will definitely out-perform. Some discussion of it here.

Thanks for that discussion link. Enjoyed it.

Can you link one of those? I would be fascinated to know how they do the detection.

Here's one. Detection is on the infrared emission from the "leader" that precedes the visible discharge. The build-up of the leader (establishing the ionized path that the return stroke follows)takes place over hundreds of milliseconds, so there is in theory time to react to it.

Yup... science degree... that, fortunately for me, doesn't have a spelling requirement. lol!!!

Thanks... A VERY intriguing solution... I've never heard of it.

I wonder if there are any issues with it being a firmware change?

They didn't say anything about setting the camera with the the mirror up, but that would prevent some of the delay.

Thanks for the suggestions. Does anyone here have actual experience taking daylight lightning? I'm interested in first hand descriptions, how it was done, how successful you were... and any tips you may have.
