I think it does much better running on a script with review off and the backlight turned down all the way, or off. Also, manual mode takes less power not having to focus or change aperture. I'll test it with the backlight off overnight and see how long it goes.
If there is a Canon mode that turns the display off completely, that should be a lot better than just turning the backlight off. This generally turns off all the display hardware and the sensor hardware when not actually shooting. Since the G1X has an optical viewfinder, I would expect it to have a proper display off mode.
Don't forget what the H stands for.

I can't get set_focus() to work on the G1X or the SX260. Tried this script as well as press("shoot_half")versions:
Code: (lua) [Select]
for f=95,100 do
  set_focus(f)
  sleep(1000) -- time to focus
  shoot()
  sleep(1000)
  print(f,get_focus())
end
The G1X camera seems to focus first on 95... then re-focuses automatically. The printout is:
95 2589
96 2674
97 2542
98 2563
In manual focus mode, the G1X obviously focuses at 95, then at the manual focus distance before each shoot(). It always returns -1:
95 -1
96 -1
97 -1

On the sx260, it focuses on 95 (I think), then crashes on the shoot() (I think). ROMLOG attached.

Also, propset5.lua isn't present in the g1x port I have.

Any suggestions or explanations would be highly appreciated. All I want to do is set the focal distance at the beginning of my script and hold it with aflock(1).

I also noticed that the Override Subj. Distance option in the CHDK menu doesn't work either. It's just ignored, except in Manual Mode, where it crashes the camera.

i just tried the latgest alpha build for firmware 1.00g.  Thank you for making it available for this cam.  It's been very comforting to have CHDK on all my compact cams.  On top of everything it offers it's given me a sense of complete continuity from cam to cam.

Bugs:

--Find that often the DNG file written to disk is a corrupted version of some previous shot instead of the current shot.

--The OSD editor crashes the camera out of the menu system; when i choose choose that option the OSD editor screen shows for a second or two then camera just drops back into regular operation.

----------------------

i have a couple of requests.  Could there be an option to change the <ALT> key?  For me it'd be good to be able to set that to the video button.  i hardly ever shoot video so it's just an orphan button, whereas i do use the configurable button a lot, the one that currently calls up the CHDK system.

i guess it'd be too complicated to ask that the dials be configurable?  Find the options offered by the builtin Canon firmware, kinda limited.

Turning of the display completely, either by closing the LCD or with the DISP button, will switch the camera back to auto focus mode. So you lose any benefit of having the camera in MF.

This is normal - you have to be in MF mode on the camera to use set_focus.

95 -1
96 -1
97 -1


This appears to be another function that has been broken by tsvstars new menu system in version 1.2.

Try the release 1.1 version - this worked for me.

Note: the minimum focus distance on the G1X is 200 (20cm).

Also, propset5.lua isn't present in the g1x port I have.

The G1X uses propset 4. I checked the autobuild server and both the trunk and release versions include all 5 propsetX.lua files.

G1X or SX260?

It works on my G1X - as noted previously the camera has to be in MF.

I haven't seen this; but I rarely use the CHDK DNG (I use the built in RAW).
If you can provide more details of the circumstances when it occurs it will help narrow down the problem.

Can't reproduce this. Which version are you using (1.1 or 1.2)?

Yes this is possible, I hadn't bothered to do this initially then forgot about it.

Probably not - it depends on exactly what you are trying to reconfigure them to do.

i just have DNG RAW save turned on all the time and every few files is one that is a corrupted version of the last one.  i have file buffer caching turned on.  i'll try and keep my brain in techy mode next time, out of the purely visual responses, quantify the circumstances better

1.2, built 2225.  i'll load up 1.1 and see, before i take it out next to use.

Thank you Phil,  This option is available in the 1.2 CHDK for the IXUS 115 / ELPH 100HS, and i found it very useful, is why i asked.

You know i'm not even sure i know what i'm saying.  My fingers are still treating the G1X like my Pentax dslr.  i think the CHDK menu option i access most often in night shooting is to change the minimal shutter speed in tbhe Custom autoISO settings, might be nice to have that on a dial if such a thing is possible.  i always have it set into the user menu, it's still a bit of fiddling.

--Does the Custom autoISO max ISO value override the ISO1600 max that's built into the autoISO in the factory firmware?

ok, i loaded up v 1.1 build 2238.  Thank you for the option to change the <ALT> button.

OSD layout editor works.

Haven't tried the DSG save yet.
