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

HOW MUCH DIOPTER DO YOU NEED?

Diopter values are based on the metric scale. A +1 diopter will result in 1 meter focus at your lens’ infinity focus setting. If you want to know the new infinity focus in feet, then you will need to convert from 1 meter to 3.3 feet. You’ll also want to work out your new minimum focus distance.

It is all a bit complicated, so we recommend you use the diopter calculator from our friends at CineSaga.

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.
