Flash Photography

When taking photos using infrared film, the position at which the subject is in focus is slightly different than that of regular film. This is because the infrared rays have a longer wavelength and the image converges behind the film plane of regular film. Use the pro- cedure described below when taking photos using infrared film.

1.Set the focus as usual. Read the point on the distance scale matching the center index of the depth scale.

2.Set the focus mode selector lever to “M” (manual focus mode). Turn the focusing ring clockwise and align the read point to the infrared index.

In addition to its standard flash sync system, the Mamiya 645 AFDIII features TTL (through the lens), off the film (OTF), electronic flash exposure metering. 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 Mamiya 645 AFDIIIs dedicated hot-shoe to a shoe- or handle- mount 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 Mod- ule is required. Please see the chart below for compatibility and/or additional adapters that may be necessary.

The resulting flash exposure automa- tion determines correct flash expo- sure and automatically adjusts the output of the flash. It also automati- cally corrects for exposure compen- sation normally required when using filters, close-up bellows or extension tubes. However, as with all TTL sys-

tems, 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.

★With TTL flash photography, the reflection of the flash is metered and the intensity of the flash is adjusted automatically, so TTL flash photography may not be able to suit to all conditions. In the cases described below, we recommend that you use a flash meter to check the intensity of the flash or to use a manual flash setting.
