Did you said "lightning"? I love lightnings! I've never claimed to be normal anyways....
You mean something like this?
These were all taken from my back yard in light rain between 9:00PM and 10:00PM during a thunderstorm.
K20D with the 18-55WR and a sturdy tripod.
ISO400, manual mode, f5.6, manual focus set at infinity. A wireless remote is very handy as well.
Since it was nighttime, I used long exposures between 5 and 10 seconds. Sometimes I used longer like 30 seconds but with a black cardboard to cover the lens ready in case of an early burst.
If it were daytime, I'd use a similar approach but compensating with ISO and aperture.
You need to take a few minutes to study the storm. Where is it heading and where is the most likely area of hits.
Sometimes, common sense is the least common of the senses: Don't do anything dangerous (i.e. stupid) that could put you or your gear at risk. Safety is key.
Boys Scouts have a good training called Hazardous Weather.
I've never tried a lightning trigger but most likely those that say "fits Canon and Nikon" will also fit Pentax. Just did a quick search on ebay and found one that says for Canon but in the description it lists Pentax as well.
Hope this helps.
Thanks!
Ismael
