the camera had built in auto-correct, so of course the RAW files dont get this treatment and result in some barrel distortion.

Photoshop doesnt have my camera profile for lens correction  (SX130). What is the most accurate way to fix the distortion?

I think, PTLens will do it, if you make the calibration files.

The Adobe Lens Profile creator program could also be useful.
