Purpose is to use outdoor where confirming focus manually is very difficult without
focus ring and EVF (SX130IS). So I take few focus bracketed shots and choose the best during
Post processing

I am trying to create a script where following process happen

1. I manually set the focus as accurate as I can.
2. When I click there are 3 shots taken in succession
     -1st with the focal length I have set
     -2nd with 0.8x of focal length
     -3rd with 1.2x of focal length

I am comfortable with uBASIC if anyone can point to a uBASIC script.

Thanks in advance

I'm not sure if you want to write your own script or use an existing script.

If you want to write your own script, here's a link to the CHDK Scripting Cross Reference page.

If you are looking for an existing focus bracketing script, here's a couple of places to start :

Focus Stacking Scripts
MF-DOF: Manual Focus DOF bracketing/stacking script
