When the lens was set to 'A', the actual aperture controlled by the Z-1p 
could be off by up to 1/2 stop. I did some visual tests and found this out. 
For this reason, I usually use the aperture rings to set the aperture.

When the lens was set to 'A', the lens communicates with the camera 
electrinocally. However, the position of the aperture resistor coupling 
below the camera mount would affect the "displayed" aperture of the Z-1p 
when the lens was set to non-'A' position. But this does not affect the 
chosen shutter speed accuracy.
