the edge of the LCD monitor is
pressed.

modes of Program AE with special
effects, "DIS" and other functions
that cannot be used together are
selected at the same time.
• The LCD monitor and the view-
finder are made with high-precision
technology. However, black spots or
bright spots of light (red, green or
blue) may appear constantly on the
LCD monitor or the viewfinder.
These spots are not recorded on
the tape. This is not due to any
defect of the unit. (Effective dots:
more than 99.99 %)
