About the Display Panel for AF360FGZ
The AF360FGZ itself does not have the function to set the FORMAT
size to [DIGITAL]. However, when it is used with a SLR Digital
Camera, the difference in focal length between a 35 mm camera and
the IC- 1" is automatically calculated based on the difference in angle
of view and is displayed on the panel (when using DA, DA L, D FA,
FA J, FA or F lens).
The conversion indicator appears and the FORMAT size indicator
disappears when the exposure metering timer of the I_-1" is on (it
returns to 35 mm format display when the exposure metering timer is turned off).

You can use [P-TTL Auto] with the AF540FGZ, AF360FGZ, AF200FG or
AF160FC flash unit. The flash pre-flashes before the actual flash and
confirms the subject (the distance, brightness, contrast, whether it is
backlit, etc.) using the camera 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 accurate
exposure for the subject than with normal TTL auto.
