Is the nikon z 600mm f 4 tc vr s worth it?
The Nikon Z 600mm f/4 TC VR S is a pro wildlife prime with a built-in 1.4x teleconverter. It's stabilised and autofocuses. On full frame it frames as 600mm, and on APS-C it gives the view of about 900mm.
Whether it's worth it depends on what you shoot. The Wildlife and sport guide is blunt about it: big fast primes like this are wonderful, but they're very heavy and very expensive. If you photograph birds or distant animals and want the best reach and speed, it's worth the investment. If you mostly shoot sport or larger animals, a long zoom is the more sensible buy.
If you go for it, I'd pair it with a Nikon Z9 or Nikon Z8, both full frame. For a lighter kit, the Nikon Z50 is an APS-C option that the lens fits, though you'll be carrying the same heavy glass.
