I'm having a problem with the set_zoom command on a PowerShot S100. When I use the set_zoom command, the resulting image has severe pincushion distortion. This only happens when I use the set_zoom command from a CHDK script. If I set the zoom manually and then take a photo with the shoot command there is no distortion. If CHDK is not in ALT mode, there is no distortion.
I've updated the S100's firmware, and I've tried setting different zoom speeds with set_zoom_speed, but it hasn't helped.
I used set_zoom without a problem on my previous cameras, an SD400 and an SD1100, but the S100 is giving me fits!
Any suggestions would be appreciated. Thank you!
