Inverter ring M54a (female to male)

The M54 male-to-male adapter should generally be suitable for connecting the two components. However, since the adapter has no central flange or stop, there is indeed a possibility that it may screw further into one component when the other component is loosened or rotated. Therefore, we cannot guarantee that the connection will always remain locked in exactly the desired position.

If there is not enough available backfocus for a locking ring, a small amount of removable threadlocker could help secure the adapter on one side. We would recommend using only a low-strength/removable type and applying it very sparingly. Permanent or high-strength threadlocker should be avoided, as this could make later disassembly difficult or potentially damage the components.

Before mounting the complete imaging train, we also recommend checking that sufficient thread engagement is achieved on both sides and that neither component bottoms out internally.
