❚❚ Aperture
Aperture is adjusted using camera controls.
Zoom and Maximum Aperture
Changes to zoom can alter the maximum aperture by up to
1 / EV. The camera however automatically takes this into
1
3
account when setting exposure, and no modifications to camera
settings are required following adjustments to zoom.
❚❚ Using the Built-in Flash
When using the built-in flash, be sure the subject is at a range of
at least 0.6 m (2 ft) and remove lens hoods to prevent vignetting
(shadows created where the end of the lens obscures the built-in
flash).

flash may be unable to light the entire subject at ranges less than
