Best budget lens for the nikon z30?
For a budget pick on the Nikon Z30, I'd start with the Nikon Z DX 16-50mm f/3.5-6.3 VR. It's a simple everyday zoom, and the VR matters here because the Z30 has no stabilisation in the body.
If you want the fast prime I recommend for people and low light, try the Viltrox AF 23mm f/1.4. It frames like a 34mm on full frame, which suits portraits and street shots well.
For wide scenes on a tight budget, the Viltrox AF 16mm f/1.8 is a good companion. Start with the zoom, then add a prime as your budget allows. The first camera guide explains how to split the spend.
