Information about flash work technique with the PRAKTISIX II PRAKTISIX II A, and PENTACON six cameras of standard type and types provided with X- and FP-contacts as well. For flash synchronization, all the standard types of our 6 x 6 cameras are provided with an X-contact, and special types are available with an X- and FP-contact. The X-contact is intended for use with electronic flashes and F- and M-class short-burning bulbs allowing exposure times as short as 1/25 sec. for electronic flashes (time setting disk provided with lightening bolt), and I/15sec. for electronic flashes. The X-contact circuit of the standard type camera is cut off in case of released shutter mechanism, and closed by operating the release button. Therefore, the release button should not be operated when the flash bulb has been connected, and the shutter mechanism been released. When the delayed action device is used, the camera has to be released via a lockable wire release. The X-contact of the special-type cameras is cut in with released shutter mechanism. Before connecting the flash bulb, the camera has to be cocked. When using the delayed-action device, releasing is possible without wire release.

The FP-contact destined for FP-class flash bulbs allows synchronization down to extremely short exposure times. When the shutter mechanism has been released, the circuit for the FP-contact is cut off. When using the delayed-action device and the FP-contact, the camera has to be released via a lockable wire release.
