My memory from the MZ-50 (on-body aperture setting, no HyperProgram, so similar to the DS/DL) is that at the open end the camera will adjust the aperture to the minimum possible; in Av and P it will set the shutter accordingly, in M it will just tell you you are now underexposing. I am not sure if it recalls that you once were at the most open so as to open up again if you zoom out; I think it did. On the closed end you have a few more stops available when zoomed in, which you similarly lose when zooming out.
