What is the nikon z 24 50mm f 4 6 3 good for?
The Nikon Z 24-50mm f/4-6.3 is a very compact kit zoom for full-frame Nikon Z bodies. At 24-50mm on full frame it covers everything from wide scenes to short portraits, which makes it a handy everyday lens for travel and walking-around shooting. It is not stabilised, and the aperture drops from f/4 to f/6.3 as you zoom in, so it is best in good light.
On an APS-C Nikon Z body it frames like 36-75mm on full frame, a more standard range. It fits a wide range of bodies, from the Z6 and Z8 to the Z50 and Z30.
If you want more light for dim scenes, lenses explains why a fast standard prime is a good second lens. For the aperture trade-off, see the aperture section.
