About the LCD Panel Display for AF360FGZ
The AF360FGZ does not have the function to set the FORMAT size to
[DIGITAL], but the difference in angle of view between standard 35 mm
format and the u is automatically calculated based on the focal
length of the lens used (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 P-TTL Auto Mode
Use this flash mode with the AF540FGZ, AF360FGZ or AF200FG flash
unit. When flash mode is set to [P-TTL auto], the flash pre-flashes before
the actual flash and confirms the subject (the distance, brightness,
contrast, whether it is backlit, etc.) using the camera's 16-segment
metering sensor. The flash output for the actual flash is adjusted based on
the information obtained from the pre-flash, enabling flash photography
with more appropriate exposure for the subject than with normal TTL auto.
P-TTL auto is available in wireless flash mode when two or more
AF540FGZ or AF360FGZ units are used.
1 Remove the cover of the hot shoe and attach the external flash
(AF540FGZ or AF360FGZ).
2 Turn on the camera and the external flash.
3 Set the external flash mode to [P-TTL auto].
4 Confirm that the external flash is fully charged and then take the picture.
