Revar Cine 138mm / 37mm Close-Up Donut Diopter +0.25

Professional Close-Focus with Creative Distortion

The Revar Cine 138mm / 37mm Close-Up Donut Diopter +0.25 is engineered for cinematographers who require precise close-focus control combined with unique visual effects. This specialized filter features a precision-cut 37mm center hole, allowing for a sharp central point of focus while creating distinct spherical distortion at the periphery of the frame.

Premium Schott BK7 Glass

Constructed from high-quality Schott BK7 glass, this diopter offers a refractive index similar to professional lens elements. Manufactured to the highest industry tolerances, it ensures exceptional optical clarity that meets or exceeds the performance of standard diopters.

Versatile Compatibility

The 138mm diameter ensures compatibility with a wide range of cinema lenses, including wide-angle glass. It integrates perfectly with industry-standard hardware, including:

• Bright Tangerine ONE Tray
• Arri 138mm rear filter holders
• Revar Cine Double Tray

Fine-Tuned Control

The +0.25 strength provides an incremental adjustment for fine-tuning close focus, ideal for maintaining a clear point of focus at approximately 4 feet on s35 sensors. The precision-cut hole ensures that when you switch between different strengths in the Revar Cine series, the center point remains exactly where you placed it in the frame.
