(Applicable to all camera groups)
3
Switch the flash mode selector from OFF to AUTO while
holding down the "ZOOM" button.
The ˙ (non-TTL Auto Flash) indictor in
the LCD panel blinks to indicate that
the SB-27 is in Forced A mode.
■Forced A mode
NOTE
• In non-TTL Auto Flash mode, choose aperture-priority auto (A) or
manual (M) exposure mode, and when the same aperture is set
on both the SB-27 and the camera, correct exposure is achieved.
• The subject will be overexposed if you set a larger (lower
f-number) aperture on the camera than on the SB-27. Conversely,
the subject will be underexposed if you set a smaller (higher
f-number) aperture on the camera than on the SB-27.
