138mm Donut Diopter: Get Closer
Precision Cut Center Hole
We cut a precision center hole allowing exact placement of the center hole in your frame when switching strengths
Premium Glass
We use high quality Schott BK7 glass that has an index similar to your lens elements. Manufactured to the highest tolerances, this glass will exceed performance of other diopters.
Hole Size Choice
Available in three different hole sizes for wide angle or telephoto lenses at various aperture settings
Extra Large Filter
138mm filter allows for use of wide angle lenses for maximum compatibility
DONUT DIOPTER: CREATIVE CONTROL
Multiple Strengths + Hole Sizes
We offer our Close Up Donut Diopters in multiple densities to fine tune your close focus and effect. +0.25 to +2 is our standard range allowing for incremental close focus adjustment.
Center Spot
Create spherical distortion with clear point of focus. This image is the +0.25 Donut Diopter at 4 feet using an s35 sensor at T4. +0.50 and up will require larger holes at the same distance to keep the same effect.
Industry Standard Holders
Compatible with industry standard holders including the Bright Tangerine ONE Tray, Arri 138mm rear filter holders and the Revar Cine Double Tray.
