Product description

Ring for exact adjustment of the distance between the corrector and the camera: The ring is simply placed over the external thread of the adaptor. Threads that are too long can be shortened with the ring. The ring also prevents threads from seizing up.

The rings are available in different thicknesses ("optical length"). The combination of different rings allows fine adjustment of the distance with much greater accuracy than with extension tubes. Unlike plastic adjustment rings, the metal rings always ensure a clean fit. The rings are always easy to remove, even at low temperatures.
