TTL Multi·Flash Adaptor AS·10
When you plan to perform TTL multiple flash operation with more than three flash units or to use the S8-15 or S8-18 as a slave flash unit, the AS-10 is required. With one AS-10 having three TTL multiple flash terminals, you can use up to three slave flash units including one mounted on it.
A tripod socket at the bottom enables the S8-168 mounted on the AS-10 to be fixed to a tripod . To per- form TTL flash photography with two units using the S8- 168 as a slave flash unit or to perform TTL photography with three units using the S8-168 as a master flash unit mounted on the SC-1?, use of the AS-10 is not always needed. Without the AS-10, however, the electrical con- tacts on the flash unit are uncovered
and can be the cause of incorrect output control.
Flash Unit Couplers AS·1, 4, 5, 6, and 7
The AS-1 , AS -4, or AS-? convert the accessory shoe of a Nikon F2 - or F3-series camera to the standard ISO-type accessory shoe, allowing direct attachment of the S8-
168.The AS-1 is for the F2-series camera and the AS-4 and? are for the F3 -series camera. A special feature of the AS -? is that it lets you change film without removing the flash unit.
The AS-6, on the other hand, is used when you want to mount the S8 -16A directly on the Nikon FA, FE2, FM2, FE, F-501/N2020, F-301/N2000, FG, FG-20, EM or FM camera. To mount the S8-16A on an F2-series camera, the AS-5 is required .
