Dunno. Don't think I got one for my FA*28-70/2.8... > 2.

I understand that the settings are for the "power > zoom" functions. However, what's the difference between "power > zoom" and "auto zoom"? Power zoom is Electrically powered zoom. Auto zoom is a function by which some cameras will attempt to keep the size of the subject constant in the frame, even if the focal distance change. Let's say (as in the Z-1 manual) that a young, beautiful woman is jogging towards you. You zoom in to make her fill the frame. If you activate the Auto zoom, the camera will automatically zoom out as she comes closer, so that the crop stays the same. > 3.

I know the Z-1 and Z-1p, and the MZ-S supports the motorised zoom functions. *istD does not. I have no idea if the other MZ- (ZX-) cameras do. > What "power zoom" functions are supported on the two digital bodies? > (Is there a difference between them in this regard?) None with the *istD.
