Nikon SB-27 Setting Forced TTL and Forced a modes, Canceling Forced TTL and Forced a modes

Setting Forced TTL and Forced A modes

(Applicable to all camera groups)

■Forced A mode

3 Switch the flash mode selector from OFF to AUTO while holding down the "ZOOM" button.

TTL	f t	m
	60	18
M mm	30	9
A ZOOM	15	4
M ISO	7	2
	4	1
	2	0.6

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.

■Canceling Forced TTL and Forced A modes

4 Switch the flash mode selector from OFF to AUTO while holding down the "ZOOM" button.

TTL		f t	m
	M mm	60	18
		30	9
A ZOOM		15	4
M ISO		7	2
		4	1
		2	0.6

The ˙ indicator in the LCD stops blinking and flash operation returns to normal TTL Auto Flash mode (for cameras in Groups I thru VI), and to non-TTL Auto Flash mode (for cameras in Group VII.)
