Vocas Viewfinder Bracket with Rosette Kit
Designed for use with any viewfinder with a rosette with ΒΌ"" threaded hole, the Vocas Viewfinder Bracket with Rosette Kit uses a NATO rail system (included) to connect the camera to the viewfinder. Its construction prevents the viewfinder from twisting and resulting in a crooked horizon in the resulting image.
