It's slightly bigger, but has a 1/4" camera thread straight into the body, a
colour viewing screen for lining up shots, and best of all, an RF remote with
wrist strap, so no more huge files or flat batteries halfway through a big
flight.
It does stills and time lapse as well, and can be charged in the car with a USB adaptor.
For a quick sample of what can be done using this camera and Windows Movie Maker (convert the .mov files with any free software), have a look at http://www.youtube.com/watch?v=fBPgb991Ne0
