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 35 mm film camera
and the/_'-7 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 1_'-7 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 77-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.
