4x5.65/138mm Single Tray Diopter: Get Closer, Faster
Built To Last
High quality anodized aluminum ring with scratch resistant coatings.
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.
Modern Coatings
We designed coatings that more closely match the spectral transmission requirements of modern sensors.
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.

Industry Standard
Compatible with industry standard holders including the Bright Tangerine Kick, Arri LMB 4x5 or MB-20, Chrosziel 450, Tilta T12 and others.
Our 4x5.65/138mm Single Tray Diopters fit into any standard width 4x5.65 Matte Box in place of the regular tray.
We also offer standard 138mm size diopters in +1 and +2 utilizing our 4x5.65 Double Tray.
Depending on your application, the best strength can vary. If you are looking to get just a little bit closer with Anamorphic lenses, the +0.50 is popular giving you the ability to go from mid-range to head and shoulders type shots easily. +0.25 is perfect for adding a touch extra close focus while keeping you close to infinity allowing for more versatile use on set.
