We recommend not using the flash when the optional Wide-converter or Tele-
converter is attached. Their shadows appear on the screen.
The flash mode cannot be selected when the exposure is locked, or after the
first still image in Stitch Assist mode.
The red-eye reduction mode cannot be used in Stitch Assist mode.
About the AF-Assist Lamp:
While you press the PHOTO button halfway, if the subject is too dark the assist
lamp may light up briefly in order to enable the camcorder to focus more
accurately (AF-assist lamp).
- The camcorder may not be able to focus even though the AF-assist lamp is
on.
- The brightness of the AF-assist lamp could be an inconvenience. Consider
turning off the AF-assist lamp in public places such as restaurants or theaters.
