Using a non-dedicated flash unit Hot shoe Flash synchro socket 1 An external flash can be attached to the camera at the hot shoe or at the flash synchro socket. 2 Set the mode dial to M (Manual mode). Select the shutter speed and aperture value. Selecting a slow shutter speed 6 increases the possibility of camera shake. However, if the shutter speed is too fast, you may not obtain sufficient flash effect. Shutter speeds between 1/200 sec. and 1/300 sec. are recommended. 3 On the flash unit select AUTO, and then set the same aperture and ISO settings selected on the camera. For some shots you may not be able to achieve the correct exposure. If this occurs, then you can experiment with different aperture and ISO settings on the external flash unit. (In this situation, the flash control mode setting on the camera is disabled.) Accessaries for Various Uses The following accessaries are sold separately: • FL-BK01 (Flash bracket) • FL-CB02 (Flash bracket connector cable) • FL-CB05 (Connection cable) See "Various uses of the external flash" on page 96 for the tip of use. Note • Some commercially available flashes have synchro terminals with opposite polarization. Those flashes need to use an adapter or some other method to reverse the synchro terminal polarization. Otherwise the flash does not fire even if it is connected to the camera. Consult your flash dealer. • The dedicated FL-40 external flash doesn't synchronize with a generic flash since the FL-40 pre-flashes. To synchronize them, set the FL-40 to MANUAL. + (plus) - (minus) Polarization of the flash synchro socket terminal 99
