1. No, not using raw. Is there a auto-correction of the lens distortion that I can turn on?
2. I tried many times taking a scene with intelligent auto & P mode, same aperture and shuttle speed was selected by the camera but the ISO is higher in P mode.
3. Oh, then must use mobile phone to take pictures with the camera on a selfie stick. Any wireless remote available for this camera ?
Connect your smart phone and use the phone as the remote.
