Had a doozy of a thunderstorm blow through last night. I was able to set my tripod/camera up and capture several decent shots before the rain & hail started. After that, I hung out under a canopy we have at work and was able to shoot in another direction.
Here's one of the better shots, although it's a bit out of focus or the setup was moving ever so slightly. I'm leaning towards that possibility since nothing appears to be in sharp focus. It's more obvious on the file before reduction for the web.
Don't remember all the specs but in general was shooting 15 seconds, f/3.5 (wide open), 28mm (36mm on the 1D), iso 100. If anyone has some suggestions on how to shoot lightning I'd be interested in hearing them. This was an unexpected photo op that I jumped on and guessed at how to shoot it.
