I am sometimes surprised why the flash does not work when I am in program mode and the built-in camera flash is released for firing by depressing the button beside the flash bulb unit. Cconsulting the Internet gave the following guidelines in Program mode:
- The camera must be set for STILL IMAGE shooting, i.e., not in VIDEO mode.
- The camera must not be set in macro mode.
- The camera must not be in movie shooting mode.
