Notes:
• The AF measuring flash is only supported in the
camera's "SINGLE AF" mode.
• When the camera's autofocus system is on, the
electronic circuit will automatically activate the
autofocus measuring flash whenever the
prevailing light is insufficient for the exposure.
• The range of the autofocus measuring flash
depends on the speed of the lens (maximum
aperture)! With an f/1.8 standard lens of 50 mm
focal length, the range is approx. 6-10 m (depen-
ding on the sensitivity of the camera's AF sensor).
• Due to parallax between camera lens and AF
measuring flash, a minimum distance of 1 m to
the subject is necessary. The AF measuring
flash will not cover the subject if the shooting
distance is less than 1 m. In such instances
ensure a higher ambient light level.
