What happens if you do a click "shoot_half" instead of a shoot ?

If I didn't screw up below, the answer is no. No matches (Set!=B4, Set!=Aft) when the following was run (on A800):

Code: [Select]

@title focusTest script
print "Focus Test2!"
for f=95 to 100
  set_focus f
  press "shoot_half"
  sleep 1000
  b=get_focus
  release "shoot_half"
  g=get_focus
  print "Set=",f," B4=",b," Aft=",g
next f
end

I then re-ran the original focus test (just in case there were user errors involved in the procedure) and things match (SetTo==Actual).

<later edit>
Uhm... I did screw up! I noticed a difference between the two scripts (delay after set_focus).

The following works (Set==B4, Set==Aft). "sleep 500" required after set_focus!:

Code: [Select]

@title focusTest2 script
print "Focus Test2!"
for f=95 to 100
  set_focus f
  sleep 500
  press "shoot_half"
  sleep 1000
  b=get_focus
  release "shoot_half"
  g=get_focus
  print "Set=",f," B4=",b," Aft=",g
next f
end

I then tried reducing the sleep 500 to sleep 50 and that failed again (Set!=B4, Set!=Aft).

Interesting - thanks for trying that out. Not sure what it means other than some things don't work the way I expected them to. Maybe someone else will weigh in.

@waterwingz

See above edit that occurred while you replied. shoot_half does work if you ensure there is a delay after set_focus.

So pretty much the same way you use set_aflock

I'm not sure we are in sync.

Note that you need a delay after set_focus and before press "shoot_half". The delay after "shoot_half" I added in because I assumed it would be required (didn't try removing it).

Code: [Select]

 
  set_focus f
  sleep 500           <<< oddly this delay is required
  press "shoot_half"
  sleep 1000          <<< this delay i put in because i assumed it would be required, didn't test without it
  b=get_focus

What I was looking for was a sequence where you set something ( focus lock or set focus ) and then have it go active with a press "shoot_half" or just do a shoot.

I think that's what we have ?

Okay. Yes, shoot/shoot_half makes the set_focus happen.

The required delay after set_focus seems to imply that the focus motor is turning before the shoot which I found odd. If that is true, why is the shoot required?

Anyway, I don't really need an answer to that... I have a recipe that works now. So on to the job of taking photos!

Ok. I will try anything that you mentioned in this thread and make reply to confirm success or not.
I simply need to have manualfocus because I am meteorolgist and I have to make photos of different types of clouds. Autofocus is good only for close things.
