Tiffen 138mm Letterbox Diopter +3/30mm

Creative Depth Control

The Tiffen 138mm Letterbox Diopter +3/30mm offers cinematographers a unique way to manipulate depth of field and focus within a single frame. Unlike standard strip diopters, the letterbox design features a 30mm open central slot flanked by high-quality diopter glass on the top and bottom. This configuration allows for sharp focus in the center while applying a +3 magnification effect to the outer edges.

Versatile Visual Effects

This specialized filter is an essential tool for experimental storytelling. By utilizing the split-focus nature of the glass, you can achieve several distinct visual styles:

• Double Imaging: Create ethereal overlays and mirrored effects.
• Selective Diffusion: Soften the periphery while maintaining a crisp center.
• Varied Focus: Bring foreground and background elements into focus simultaneously across different planes.

Designed for professional matte boxes, the 138mm diameter ensures compatibility with industry-standard cinema lenses, providing a robust solution for demanding production environments.
