Save this script as focus_int.lua and give it a try :
It might be easier to lock the focus rather than waiting for the camera to focus before every shot. You do this with:
set_aflock(1)
If you take a picture that's in focus before starting the script, then this should work:
--[[
@title Intervalometer
@param a = interval (sec)
@default a 15
--]]
set_aflock(1)
repeat
start = get_tick_count()
shoot()
sleep(a*1000 - (get_tick_count() - start))
until ( false )
Also, sometimes shoot() returns with get_shooting()==true if you call it too soon (i.e. 1 second interval). Then it stops taking any pictures. Before returning, shoot() should do something like this:
release("shoot_half")
while(get_shooting())do sleep(10) end
