Nikon Camera F3AF - Manual (Page 92)

Speedlights SB-11 and 14
For those photographers requiring a separate bracket-mounting
unit, Nikon has the SB-11 and SB-14. The guide number of the
SB-11 is 36 (ASA/iSO 100 and meters) or 60 (ASA/iSO 25 and
feet), whiie the SB-14, which requires a separate battery pack,
has a guide number of 32 (ASA/iSO 100 and meters) or 52
(ASA/ISO 25 and feet). For automatic TTL controi, these units
must be used with the TTL Sensor Cord SC-12. Featuring tiiting
fiash heads, the SB-11 and 14 ailow you to bounce the iight
easiiy off the ceiiing or walis for softer, more fiattering lighting
for portraits.
Flash Unit Couplers AS-3,4, and 7
To mount other direct mounting flash units on the F3AF's acces­
sory shoe, a Nikon Flash Unit Coupler is required. The AS-3
coupler is necessary when mounting the Nikon SB-7, while the
AS-4 or AS-7 is for the SB-15, SB-E, or SB-10. A special feature
of the AS-7 is that it lets you change film without removing the
flash unit.
