Cautions when using the flash
When taking macro pictures on the wide-angle side, the flash light
may be missing in some parts or the light volume may not be
uniform.
Depending on the conditions at the time of shooting (clarity of the
water, suspended matter, etc.), the applicable flash distance may
become shorter. After taking a picture, display it on the LCD
monitor for confirmation.
