In the last winter I finally succeeded in photographing a lightning bolts, and not one, about ten of them.
To shoot a lightning we'll need to use long exposure of course, and not as someone from my work has asked me (how was you able to click on the shutter this fast? :-) )
an exposure of 20-30 seconds is recommended.
The key point is to wait for the thunder and try to examine the wait period between the thunder and the next lightning.
Then using the 20-30 seconds exposure catch the bolt.
Few examples of that kind:
You know the phrase "lightning does not hit the same place twice", well I guess it does not but at least very close.
While the to images above are in a wide angle shot, I was able to zoom in to a specific place and guess what, the lightning hit the same place twice:
don't give up, catching a good frames of 10 lightnings took me about 50 shoots. :-)
Waiting for the next winter.
