A: This lens would better suit the Z50 or even a Z7. Since it's a DX lens, on a Z6/Z6ii you would get half the resolution (so about 10-12mp). On a Z50 you would get the full 20 mp, and a Z7/Z7ii still would have plenty of resolution. In short, it's not optimal for a Z6/Z6ii. The image quality will be quite lower than you're used to but it can work depending on your needs.
