14 Use of the Flash
14.1 Flash Operation with the Sinar Hy6 System
For flash operation with the Sinar Hy6 system, external flash units are connected to the
camera. With the Sinar Hy6 system, fixed flash units and off-camera units can be used.
The Sinar Hy6 system is equipped with a between-the-lens-shutter; therefore it offers very
short flash synchronization times (up to
1000
1
sec). The Sinar Hy6 system is x-
synchronized with the minimum possible shutter time of the lens. In this way, the flash is
operated independent from the exposure control of the camera, and the exposure time is
not extended when working with the flash.
The Sinar Hy6 system offers the following interfaces for the flash
Hot shoe
Connection of TTL-compatible flash devices and SCA-adapter
X-contact
Flash synchronization socket for x-synchronization of studio flash devices
Mechanical
interface
Attachment of an external flash device at the 90° reflex viewfinder
14.2 The Hot Shoe – TTL-Flash Measurement and SCA-interface
Using the hot shoe, TTL-compatible flash devices and the Rollei SCA-3562 Flash Adapter
enabling special flash functions can be attached to the camera. TTL-measurement, flash
synchronization and the transfer of the relevant camera data (e.g. aperture, ISO-standard)
are carried out via the hot shoe.
The following information is exchanged between the camera and the flash device:
• Focal length of AF-lenses for the operation of the reflector
• Aperture values
• Film sensitivity values for the operation of the computer control of the flash device
• Flash correction with the suitable flash devices
• Control of the AF measurement flash
In case of any questions concerning recommended flash devices, please contact your
expert dealer.
