Is there a way to make the camera refocus when you zoom during video recording?

With CHDK you can manually refocus after zooming (in ALT mode: up/ISO key and then "zooming"; change the factor with left/right). As far as I can tell there is no code that automatically refocusses during/after zooming, but I did find the necessary functions in the firmware to enable autofocus with the press of a button. I will make a patch for this and submit it for addition to the autobuild later (with some additional fixes).

Does the latest build have support for refocusing?

I also found this on chdk.wikia.com:

"Note 1: Camera does not refocus automatically after the end of zooming. Use a click or press/release "shoot_half" command to implement a refocusing if needed."

Does anybody know the steps involved in triggering a refocus on a half press? Is there a script that can do this?

Yes. I forgot to make a post regarding the latest build. Refocusing during recording and optical+digital zoom in video mode should both work now (but you have to shortly stop zooming out when going from digitial to optical zoom). Also, as reyalp noted, the latest build has a fix for the problems when (for example) you tilt your camera and the menu disappears.

In the CHDK menu, set "Video Parameters" -> "AF key" to "shutter" (half press shoot) or "set" (func set).

Nice work as always, thanks!

Is it possible to enable a Time Lapse feature through CHDK or will Canon have to release a firmware with this option?

I love that feature from my previous Canon and was sad to see it gone from the SD880 when i upgraded.

You can use scripts to do this in CHDK. See the scripting forum http://chdk.setepontos.com/index.php/board,7.0.html and the wiki http://chdk.wikia.com/wiki/UBASIC

Thanks reyalp. I'll check out the scripting forum.

I'm having a lot of fun with CHDK on my Ixus 870. Thanks a million for the port!

Just one question: I've read about a "DNG visible via USB" option, but I can't seem to find it. Am I looking in the wrong place, or is it left out on the Ixus 870 for a reason?

Thanks again.

It's not there mainly because the reference port I used (SX10) does not have it. I'll have a look at it.

Unfortunately, the method we used to do this on older cameras does not appear to work on many newer (digic IV ?) cameras. This includes both SX10 and SD990.

Hi, I've been following this thread for awhile. The efforts of the involved programmers are very much appreciated. Too bad I have no relevant knowledge to help. Besides showing my gratitude, I would like to ask if the current beta version is mature enough to be used to build the StereoData Maker variant? I am anticipating to try this camera on stereoscopic pictures.

Best regards.

As far as I know there haven't been any reported problems anymore (except for one vague unreproducible one). This seems to suggest that the port is pretty stable. I'm not sure what the requirements are for SDM, so I can't comment on that.

Another question that follows from yours is whether or not we can remove the beta status from this port.

[Gruga]

Thanks mweerden for the prompt response.

It is great to hear from you that the port is stable. Yeah right if the beta status is removed, it might provide a green light for the next great group (SDM group) to go ahead. I really do hope so.

Is there any procedure that the port has to pass to have its beta status removed?

Yes, I have already done that.

What firmware version is your camera ?

One little problem ... synch shooting with USB switch is not working correctly.

This is unusual, I am trying to fix the problem.

I am still keeping the money for the 2 cameras.
I'll run to purchase them if I get the SDM software.

*snap* Ouch, the synch shooting is not working?!
Thanks Microfunguy. Please keep up the good work. I am waiting for your good news.

Regards.

Hi, Microfunguy. Is it possible that I can get the SDM software for ixus870?

And, maybe, is there any way that I could help solving the problem by trying out the software?
