Viewfinder adapter with 90-degree deflection – enables comfortable working at low angles, overhead positions and tight angles. Protects the back and expands camera positioning possibilities.
What is a Right Angle Viewfinder?
The Right Angle Viewfinder (German: Winkelsucher) is a viewfinder attachment that redirects the view by 90 degrees. It allows for comfortable operation in extreme camera positions – low-angle, overhead, tight spaces – without the cinematographer having to contort themselves.
