According to my testings, you don't need to restart your camera between turning on and off AF lock in the script. BTW, it seems to me that the script works better on alpha6 than alpha7. I don't know why, but smth should be wrong with alpha7 :blink:
@waterwingz
There is total difference between "shoot" and "shoot_full" commands. I think, that the second is for our and, maybe, all the DIGIC IV and higher cameras, but the first is for older ones.

alpha7 enabled the code that allowed zoom in video mode.  Seems really unlikely that it would have any affect at all on how well your script works.

If you look at the CHDK code, you will see that is not true.   The "shoot" command just issues a press(shoot_half)  followed by a press(shoot_full) and then a release(shoot_full) and release(shoot_half).

That's why I said "I don't know why" :)

I've tried many intervalometer scripts before and all they stopped after 1 or 2 shoots and all of them had "shoot" command. That's why I think that there is a difference between these commands.

Clearly they work differently based on your testing.   Did you find this to be true on any other cameras than the ixus1115 ?

No, I only have 100 hs.

Okay - so just for the record of someone trying to follow this thread someday  - the issues we are seeing with shoot are related to the early nature of the ixus115 porting code and nothing to do with it being a DIGICV processor.

When that script starts,  focus is only set once at the start.  According to the code, it should not attempt to focus again while the script is running.
O.k. - that was my error.

But are you saying that if you stop the script and restart it,  it does not focus the second time ?
Up to now, it is a one time observation, that - after the script ended and restarted and also, when I switched to normal mode - the camera didn't focus, when I half-pressed the shutter. If I manage to reproduce this behavior, I'll write more about it.

Sorry to interrupt the thread, but I just learned all this stuff about raw format in the previous weeks. I used to have a Cannon Powershot 890 sd that made pretty good panoramas (and had a superfine mode). Then I got this Elph 100 HS thinking it was an upgrade and all of a sudden my panoramas were less sharp. Then I learned of raw format and compression.

If you guys are in need of a tester, I have pulled the alpha 5 version off this thread and played around with it. I hear there is an Alpha 7 version, but I don't know where to get it. I don't have a lot of time to test at the moment, but if the problem isn't fixed by September, I will have more time to dedicate to getting this working.

I have some programming knowledge, is there a thread that discusses the workings of CHDK and getting it ported to a camera? If so please let me know. Otherwise let me know if you need a tester for the 101.a firmware version of the port for this camera.

The alpha7 is here: http://chdk.setepontos.com/index.php?topic=6751.msg87048#msg87048

Possibly scripts for shooting need to be tweaked, as there is (with alpha7/1.01b) a problem with the shoot command. Replace these commands with e.g.:

       press "shoot_half"
        sleep(500)
       press "shoot_full"
       release "shoot_full"
       release "shoot_half"

(shoot_half, sleep... : you need to experiment a bit with the value and if and where shoot_half and more is needed)
siak changed the intervalometer script this way (and a bit more), so that it works with alpha7:
