But i think this (zoom rocker with half-pressed shutter) isn't practicable on the Ixus models (also on some of the A-series ?), the shutter button and the zoom rocker are affiliated with each other, the shutter button in the center of the zoom rocker rotates with the zoom rocker.
It would be very helpfull to become the automatic focus value from the last auto-focusing as the start-value for the CHDK-manual focusing feature.
...but as I said there is no choice...
...Yes, I personally agree with you, but it could also break some habits, I don't know if some people like that their manual value is saved.......What I would like to do too, is to add a factor "auto", that would automatically set the factor to a fraction of the DOF (based on the idea that you don't need one millimeter increment at one meter distance), and also to progressively increase increment when the key is kept pressed.
You don't need a script, you can use for instance the shortcut "up" when in alt-mode, it will enable manual focus, and then use the zoom rocker to change its value (subject distance in mm), and left/right to change the factor.
...@cyril42e, does this shortcut work in all builds? I'm using allbest with the SD500 and I can't get this to work... maybe a newbie mistake, but I've tried everything and can't get it into manual focusing... In Alt mode, neither "Up", nor Half-press and Up do anything for me... ?? ...
Joe, what version are you working with ? I'm not sure whether this feature is in the older builds - you can try the latest Autobuild version (Allbest #51-437) or the experimental JuciPhoX build (Thread : the collaborative CHDK build - direct download from here).
is this because my cam doesn't have a manual focus button? do other cameras which are Auto-focus only work with this feature?
