The ˙ (non-TTL Auto Flash) indictor in the LCD panel blinks to indicate that the SB-27 is in 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.
