Is the nikon z 35mm f 1 2 s worth it?
Worth it if you shoot in low light, at events, or want very shallow focus for portraits. f/1.2 gathers a lot of light, and on full frame it gives a natural 35mm view.
If you're buying a body to go with it, the Nikon Z6 II is a full-frame option that suits this lens well for low-light work. The Nikon Z50 II also fits, but on APS-C the lens frames like a 52mm, which is a fine portrait length, though not what this lens is really for.
For most hobby shooting, lenses matter more than the last stop of sensor performance, so only spend on this one if you'll really use the f/1.2. Read Sensor sizes to decide, and compare it with the Nikon Z 35mm f/1.8 S.
