A flash sensor located inside the camera body reads the flash reflected off the film surface at the moment of exposure. The sensor is connected via the Phase One 645 AF s dedicated hot-shoe to a shoe- or handlemount style Metz flash unit via the Metz SCA 3952 TTL Adapter. Maximum flash sync speed is 1/125 sec., making daytime synchronization possible.

The ISO of the flash is automatically set through the TTL connection from the camera’s Film Magazine; any adjustment to this is instantly recognized after the setting is locked and the shutter release is half- pressed. Also, when Film Magazines with different ISO settings are switched on the camera body, the TTL flash connection instantly recognizes the change.

To utilize the TTL flash feature with all TTL-operable Metz flash units, a Metz SCA 3952 Module is required. Please see the chart below for compatibility and/or additional adapters that may be necessary.

The resulting flash exposure automation determines correct flash exposure and automatically adjusts the output of the flash. It also automatically corrects for exposure compensation normally required when using filters, close-up bellows or extension tubes. However, as with all TTL systems, it requires manual compensation for differences in film surface reflection characteristics. The amount of compensation is determined by experimentation and is performed on the Mamiya Film Magazine ISO setting.

1.Mount the SCA3952 adapter onto the Metz flash, insert fully into the camera’s hot shoe, and then tighten with the locking knob.

2.Set the exposure mode, and then check the shutter speed and aperture.
