Page 14 in the manual shows the indicator on the LCD, what x factor, and whether you have Smart Zoom or Precision Digital Zoom engaged.
I have my camera set for 10mp auto-focus. Is there an "indicator" when I use the "zoom" to let me know when I have exceeded the "3x-optical" capability and began using "digital zoom". I have heard that "optical" is better than "digital", but neither the instruction manual or handbook mention an "indicator". THANKS
