Hi,
I'm new in CHDK.
In the <Alt> menu I can enable manual focus via 'UP'.
After switching the camera on this is always Off.
Is there a script command to set it On like via <Alt> menu?
Thank's in advance.

Go to the "Enhanced Photo Operations" menu and scroll down to the bottom where it says Disable Overrides on Startup. Disable that option.

set_aflock()

This is a work in process : http://chdk.wikia.com/wiki/CHDK_Manual_Focus_and_Subject_Distance_Overrides - I'm still working on it.

There's also set_mf(x).

But I can't make out any difference to set_aflock(x) from the description:

set_aflock( ) causes the camera to focus and then lock the resulting focus setting such that it won't attempt to refocus on subsequent shots.

set_mf( ) is used to enable Canon's built-in manual focus ( MF ) mode so that the set_focus( ) function will work. It's not needed for all cameras - the get_sd_over_modes() function can be used to figure it out for a specific camera.
