if you have a real MF AI/AIS lens then you'll be stopping down the aperture with a twist of the ring and the DoF will be shown for that aperture. Other MF lenses like the Nikon D or third party with electronic communication control the aperture via the camera. The Z's only stop down as far as f5.6 for focussing or metering so I assume that's the same for AI/AIS. At any rate it looks like itA question for Z owners who use AI/AIS glass with the FTZ adapter:
Does the aperture behave exactly like the F mount, I.e all focusing/metering is done wide open even if you select a smaller aperture, only stopping down to the desired aperture when the shutter is released or is it a ‘dumb’ adapter in the sense that turning the aperture ring immediately causes the aperture to close?
