Time to be an iconclast.....
While I'm a BIG fan of Pentax K5 time lapse videos, the idea of adding hundreds (or thousands) of shutter actuations for each video is a bit stressing. To off-load this burden, I've begun to take advanage of Canon Point aned Shoot (hertic!) cameras outfitted with the Canon Hackers Development Kit (CHDK) software
CHDK Wiki
CHDK adds interval shooting capabilities to most Canon cameras and if I burn thru 100k shutter actuations in 6 months with a used Point and Shoot so be it. Of course, the quality is not the same, so in my next major effect, I'll use a Point and Shoot for landscape and sky stuff and the K5 for the detailed time lapse stuff. Just trying to offer some additional tools.
If you are interested here is a 3:00 minute time lapse of sky, clouds, sunset and full moon rise with a 7.1MP Canon Point and Shoot. Yea, its not K5 quality, but the video reflects over 5,000 images displayed at 30 fps. And with a small point and shoot you can also grab 360 degree video shots (
