• When shooting subjects within the 5 to 46 cm
(2.0 in. - 1.5 ft.) wide angle range or the 26 to
46 cm (10 in. - 1.5 ft.) telephoto range, use
Macro mode.

shoot the image. (See Shooting Problem
Subjects for the Autofocus (p. 87))
• Set the flash on.

lens and subject should not exceed 4.2 m
(14 ft.) at wide angle and 2.5 m (8.2 ft.) at
telephoto (When sensitivity is set to AUTO).
