Time lapse on A460, focus lock breaks in script

Hi all, thanks for help in advance...

I wanted to write a simple script to record cloud formations. Problem with my script is that
the camera wants to refocus after every shot. Is there a way to lock focus other then press "half_shoot"?
Or am i just doing it wrong? I'm a programmer, but i'm reluctant to go into source at this point.

Oh yeah, i forgot to mention i tried with SDM-CHDK (StereoData Maker) 1.70 and
allbest-a460-100d-51-421, same result.
Here is the script i'm using:

@title IntShot (press)
@param a Interval (Minutes)
@default a 0
@param b Interval (Seconds)
@default b 15
@param d Times (1)
@default d 0
@param e Times (10)
@default e 1
t=a*60000+b*1000
l=e*10+d

if t<5000 then let t=5000

print "Focus in 3s.."
sleep 3000
press "shoot_half"
sleep 4000
for n=1 to l
click "shoot_full"
sleep t
next n
release "shoot_half"
end

Just a guess, but I think maybe you have to replace 'click "shoot_full"' with 'press "shoot_full"' and 'release "shoot_full"'.

Thanks, i did try that, and i tried following 'click "full_shoot"' with 'press "half_shoot"' too.
Neither worked.

Try to use the "manual mode" on the camera.

This is scripts (time laps) that have been working for me (A460). You can try this


rem Johan Van Barel 07-07-2007
rem Interval for Canon A640

@title Interval
@param a Number of Pics
@default a 2
@param b Interval (Min)
@default b 0
@param c Interval (Sec)
@default c 10
@param d Initial Delay (Sec)
@default d 1

if a<2 then let a=2
if b<0 then let b=0
if c<0 then let c=0
if d<0 then let d=0
t=b*60000+c*1000

print "Pics:"; a
print "Total Time:", t*(a-1)/60000; "Min", t*(a-1)%60000/1000; "Sec"

sleep d*1000

print "Pic 1 of", a
shoot
for s=2 to a
    print "Wait",b;"Min",c;"Sec"
    sleep t
    print "Pic", s, "of", a
    shoot
next s

end
