Yes, I was saying to turn the display on just to see that the focus was no longer manual.

it's when you turn display off that it goes in autofocus. As I was saying:

i.e. as soon as you trn the display off the camera reverts to autofocus

How to determine this? because in the night the camera stops focusing properly if the display is off!!!

first of all, i'm not using a570 or a590 but a550.
second: i'm using manual focus, set by CHDK - subject distance
third: i make lots of night shots, and no focus problems + lcd off.

hope this helps.

Ah... that's not manual focus then.

That's autofocus which gets overriden using CHDK (this difference may be relevant for speed and lifetime of the camera's mechanical parts in very long timelapse use).

-->set-up the script
-->press alt(so you return to the normal canon menu)
-->switch off the display(with the disp button)
-->press alt(you come bach to the chdk menu)
--->than you press the shot button and the script will start with black display!

I'm trying to do this right now with the motion detection script and it doesn't seem to work. Is it because it uses the display for motion detection, or am I doing it wrong?

Short answer: Yes.

Long answer: Yes, for two reasons
1) Motion detector reads the live preview display buffer to find motion. If it isn't updated, there's no motion there.
2) When you turn off the display, only part of the power savings come from shutting the display and its backlight down. The camera also powers down the image sensor and things like manual focus and aperture. When you switch display off using the display button, there's no way the motion detector could work...the lens stays out so that you can take a photo reasonably fast and without wasting power in those motors, but don't let that fool you: the camera has it's eyes closed.

Thanks for the info, that makes sense. Do you know if there is any way to plug in an AC power adapter to a Powershot SD1100 / Ixus 80? I'm not sure if it even has a spot for a power adapter, but there is at least one jack that I don't know what its used for (I think its AV out though).

to use an external PS on the sd1100 you need to get a dummy battery. if you look at the batt. door thers a little rubber flap where plug into the dummy batt. canon sells for around $70.
or you could try to make a dummy batt.
crappy set up.

Good to know that Canon sells them though! And then they plug into the wall? That actually sounds like it might be useful, but I'm not going to go out and buy one right now ;-)

I've got a SX110, and I'm trying to run the Ultra intervalometer script with the display off. I have tried turning off the display, then entering ALT and starting the script, but that turns on the display as soon as the first shot is taken and the screen is never turned off after that. Is there another way to do a timelapse with the screen off? Is there a better script I should be using?

I should add that I'm willing (and probably able) to modify an existing script to accomplish this if necessary.
