What lenses should I buy for the nikon z50?
For the Nikon Z50, I'd start with the Nikon Z DX 16-50mm f/2.8 VR. It covers roughly 24-75mm on full frame, which is about right for everyday shooting, and the VR helps because the Z50 has no stabilisation in the body.
For reach, add the Nikon Z DX 50-250mm f/4.5-6.3 VR, which works out to 75-375mm on full frame.
If you shoot in dim rooms or want a small, light setup, the Nikon Z DX 24mm f/1.7 is a good fixed lens to carry alongside the zoom. For more on how focal lengths translate on this body, see the focal length converter.
