I'm a meteorologist who loves storms and am only now getting more into the photography aspect. I recently purchased a 30D along with the canon 70-300 IS USM which I love...and the kit lens has treated me relatively well also.
What I'm wondering is what the best lens for photographing lightning is. These would generally be long exposures - anywhere from 2-20 seconds. A long lens is not needed, as a anything with a moderate wide to moderate tele would cover the portion of the sky I'd like to frame.
Does anyone have any good experience shooting lightning? With what lens? What exposure settings did you find to be the best?
Thanks in advance.
