Prolunga Anello regolazione fine T2 1,0 mm

Ring for precise adjustment of the distance from the corrector to the camera: The ring is simply placed over the external thread of the adapter. Too long threads can be shortened with the ring. The ring also prevents threads from seizing.

The rings are available in different thicknesses ("optical length"). The combination of different rings thus allows a fine tuning of the distance with much higher accuracy than with extension sleeves. In contrast to plastic tuning rings, the metal rings are always guaranteed to be clean. The rings are always easy to remove, even at low temperatures.
