Manual Focus Parameter Ignored for A2200 #107

Closed duerig closed 10 years ago

duerig commented 10 years ago

I'm fairly certain that the way manual focus is set is not working properly for A2200 cameras.

The CHDK manual mentions that setting manual focus on various cameras is extremely idiosyncratic: http://chdk.wikia.com/wiki/CHDK_Manual_Focus_and_Subject_Distance_Overrides

The A2200 reference notes that setting manual focus on this device can only happen after autofocus has been locked:

http://chdk.wikia.com/wiki/A2200

But the actual flow of the lua commands has autofocus lock turned on only at the end. This means that the focus parameter in the configuration is ignored when setting up the cameras. I have noticed this in practice on pages with only a small amount of text.

I am working on a patch.
