Old Nikon lens with z5

Hi, I recently got a z5 and was looking at getting a higher zoom lens for it. The new z range of lenses are about $2,000 for a 70 to 200 mm. So I'm thinking of getting one of the older zoom lenses like this one https://www.adorama.com/us1907858.html I know I have to pay another $200 or so for an ftz adapter. And I'm pretty sure this old lens is FX compatible. But my question is, is there any big disadvantages to getting this old lens or anything obvious that would be missing from this old lens as opposed to the new z range? Thanks very much.
