Is the nikon z dx 18 140mm f 3 5 6 3 vr good for sports?

It's a reasonable starter, but I wouldn't pick it as your main sports lens. At 140mm on APS-C it frames like about 210mm on full frame, which is useful reach for school sport or sideline shots in good light. The catch is the aperture: at f/3.5-6.3 it gets slow as you zoom in, so you'll need bright conditions or a higher ISO, and fast action can get blurry.

It is stabilised and autofocuses, which helps. If you shoot sport regularly, an APS-C body like the Nikon Z50 or Nikon Z30 pairs well with it. The lens also works on full-frame Z bodies such as the Nikon Z6 II in crop mode, though that gives you fewer megapixels.

For the reasoning behind all this, see wildlife and sport. It's the hardest kind of photography, and a longer, faster lens will make a bigger difference than the body.
