...One of the scripts I've tried has an option in it for setting the focus to infinity, but all the reading I've done on here says the way the scripter wrote it, it shouldn't work. This one specifically is yass and it's uses set_prop 6, which about mid way down on this page, http://chdk.wikia.com/wiki/UBASIC/propertyCaseUse says property 6 can't be set. Does this work on other people's cameras?
I've tried turning on the G9 camera, getting out of "ALT" mode, using Av and setting the MF to infinity. Then I get back into "ALT" mode, start the script by pressing the shutter button and immediately it refocuses to something less than infinity.
If you put your camera to MF mode and then start a script that doesn't emulate keypresses to exit MF mode and doesn't call any commands relating to focus (including writing to any propcases relating to focus) and doesn't shut down the LCD or visit PLAY mode, then your focus shouldn't change.
on page 126 of your G9 Users Manual, it mentions that while in Manual Focus, pressing the shutter halfway will cause your camera to Auto Focus.
Wicked...are there more models that do this? Sounds like a feature that makes Canon's MF mode nearly useless (or very annoying) for people who commonly use zebra, histogram, DoF calculator, fast react MD or other CHDK features or scripts that do their magic during half shoot.Also sounds like something that would be rather hard to disable by CHDK but maybe could somehow be worked around by e.g. making CHDK poll for MF mode and setting CHDK focus override to new focus distances unless it changes during half shoot.

...Technically, I have two problems. I have an interval timing issue and a manual focus issue...I'm trying to combine the functionality of two scripts that I've found...Program "Intervalometer.bas" has accurate timing on my G9...Program "intervalometer with day and week" is the functionality I need, but has very erratic intervals on my camera.I found safety MF to be propcase 277 for digicIII cameras...the listing for that propcase doesn't say whether or not it's a RO or RW, it's blank. I'm guessing it's not been confirmed if it works?
After looking at both of the scripts I decided to create my own version - I still need to finish testing, but should have something for you soon. There will be no PropCas statements, so you should be able to use it on your G9.
