Non-CPU Lenses
If the maximum aperture of the lens has been 
specified using the [Non-CPU lens data] item in 
setup menu (pg. 197) when a non-CPU lens is 
attached, the current f-number will be displayed 
in the viewfinder and control panel, rounded to 
the nearest full stop. Otherwise the aperture 
displays will show only the number of stops (
F, 
with maximum aperture displayed as 
FA) and the f-number must be read 
from the lens aperture ring.
