What lenses should I buy for the nikon z50 ii?
The Z50 II has no stabilisation in the body, so I'd lean towards lenses with VR built in. For an everyday kit, the Nikon Z DX 16-50mm f/3.5-6.3 VR is a sensible start. It's small, stabilised, and covers most of what you'll shoot.
For reach, the Nikon Z DX 50-250mm f/4.5-6.3 VR goes to about 375mm full-frame equivalent, which suits wildlife and sport, and it's designed for this crop body.
If you want a brighter standard zoom later, look at the Nikon Z 24-70mm f/2.8 S. It costs a lot more, so I'd only buy it once you know you need that speed. Since you're buying into a mount for years, it's worth checking how to choose before you commit.
