Well I don't really agree that is a great shot. Yeah I just put the A610 on manual, f8 and for some reason dialed in a 1/100 shutter speed trying to get a proper exposure. So I think this was a bit of a fluke. Most of the "leader" flashes were just too dim in the daylight to set it off and I couldn't lower the threshold since I was hand holding the camera. But that shot was definitely triggered by the motion detection. As usual though every time I pointed the camera to a different part of the sky, there'd be a good strike where I was looking previously. Always the way isn't it.
I tell you though, just as I put my arms down for a rest the last time, there was a beautiful bright forked strike right where I had the camera pointed, not much more than 1km away going by the thunder delay. And with an easily discernible delay between the pre-flash, just like with the successful capture. If I had have got that, I think we all would have peed our pants.
