The AF360FGZ will automatically convert the field angle differential
between 35 mm format and the U depending on the focal length
of the lens you are using (when using DA, D FA, FA J, FA or F lenses).
The conversion indicator appears and the format size indicator disappears
when the exposure metering timer of the U is on (it returns to 35
mm format display when the exposure metering timer is turned off).
* Using wide adaptor
Use this flash mode with the AF360FGZ flash unit. When flash mode is set
to “P-TTL auto”, the flash pre-fires right before taking pictures using 16-
segment metering and allows more precise control. P-TTL auto is
available in wireless flash mode when two or more AF360FGZ units are
used.
1 Remove the cover of the hot shoe and attach the AF360FGZ.
2 Turn on the AF360FGZ.
3 Set the AF360FGZ flash mode to P-TTL auto.
4 Confirm that the AF360FGZ is fully charged and then take the picture.
