That's what I have been doing. It should work from the chdk menu too, a bug?
Yes. See the forum thread that I linked in my previous posting.
It won't re-focus. It doesn't work. It looks like the camera need to be in MF for the SD override.
Testing reveals that the camera will focus without being in MF mode. However, the current CHDK configuration for the SX160 incorrectly prevents this from happening.
I see. I was hoping that the same code could be used.
It is the same code. But the configuration changes from camera to camera.
I can rebuild the existing code with corrected configuration data and send you a test version if you want to test it. On completion of a successful test, the autobuild can be updated for the SX160.
Or if you can wait a bit, there is new code coming for the 1.3.0 version of CHDK that will fix all of this.
