>>4281172a great zoom is the z 24-70 f4. it's uber sharp and can be had for like $300 used. (it was the z6 kit lens for years).
then shell out on the z 50mm f1.8s - best 50mm prime you can get. will set you back $400 used but it's worth it.
adapting f glass works but it's meh quality compared to native z glass.
