Camera Adaptor Nikon to M42 / ULTRASHORT

T2 adaptor ring for Nikon bayonet

This adaptor screws directly into the Nikon body and enables you to connect objectives with T2 (M42x0,75) thread.

The Nikon bayonet is much wider than T2 so the adapter can be mounted completely into the camera body. The real optical length is 0mm.

Applications:

- very short Adaptation T2 threads to the Nikon cameras

- In astro photography, the backfocus of some telescopes is so short that it's not possible to bring a SLR camera with standard T2 ring (+10mm) into foucus.
