In reply to Thelongcon:
With reference to an intervalometer, I came across this yesterday, so will give it a go tonight. If it works it should be really useful :-
"not sure what you need for intervals... but the "antishock" feature can act as an intervalometer.
Set it to 8 seconds, then put a rubber band around the shutter release.
Voila ! 8 second intervals.
You can go up to 30 seconds I think. Plus, if you put the timer on as well, you can boost the interval by an additional 2 or 12 seconds."
