I have a Soligor 450mm lens with a threaded mount and want to try it on a Nikon D90. I believe it may be an M42 screw-mount lens. Are there adapter rings for mounting it to Nikon F, and will autofocus or infinity focus work?

Soligor 450mm lens is a manual focus lens. There should be adapters, but none of them will make AF work.

Yes—if the lens is an M42 screw-mount model, M42-to-Nikon F adapters are commonly available.

A few important limitations apply:

  • Autofocus will not work. This Soligor is a manual-focus lens, and a simple mount adapter will not add AF capability.
  • Infinity focus with M42 on Nikon F is normally problematic because Nikon F has a slightly longer flange distance than M42.
  • You’ll typically find two adapter types: plain mechanical adapters, or adapters with a corrective glass element. The glass versions can preserve infinity focus but may reduce image quality.
  • In this specific case, because the register difference is only about 1mm and the lens is a very long 450mm telephoto, you may still be able to reach infinity with a plain adapter, since long lenses often focus a bit past infinity.

So: an adapter likely exists, but expect manual focus only, and infinity focus depends on the exact adapter and lens tolerances.
