I know that AF-S, AF-D and AF-P lenes will, and will atuofocus properly because the have built in focusing motors. The Nikon Z50 dose not have a focus motor and thus needs a lens with it's own focus motor. I guess what I am asking is, does this lens have a built in focus motor?
No, these are screw drive lenses, that require an in camera motor drive to auto focus. You can still use them on a camera without an in body motor but, they will be manual focus only.
