ARRI Diopter Frame 138mm

Professional Close-Up Control

The ARRI Diopter Frame 138mm is a precision-engineered accessory designed to integrate 138mm diopters into lightweight matte box systems. By occupying the space of two standard 4x5.65 inch filter trays, this frame allows cinematographers to achieve stunning close-focus shots without the need for heavy dedicated hardware.

Seamless Integration

This frame is fully compatible with the ARRI LMB 4x5 and LMB-25 matte boxes, fitting securely into 2- or 3-filter stages. It supports diopters up to +2 strength, though users should verify clearance for specific high-profile +2 optics.

Enhanced Safety and Versatility

• Integrated Safety Catch: A dedicated mechanism ensures the diopter remains secure during lens changes or frame swaps.
• Mounting Options: Dual 1/4 inch threads allow for easy attachment to articulating arms for off-camera use.
• Dual-Slot Design: Efficiently utilizes matte box space while maintaining a lightweight profile.
