NEW - 10x Diopter Eyepiece Adjustment Piece for BOLEX 16mm Movie Camera

NEW! HARD PLASTIC.

10X VIEWER DIOPTER EYEPIECE ADJUSTMENT RING

for ALL BOLEX 10X VIEWERS ONLY.

You must be 100% sure the screw post is indexed into the adjustment channel or you will break this ring. That is how these break. The screws come loose, and people try to tighten it down and the post is not lined into the groove.

SCREW NOT INCLUDED.
