138mm Diopter: Get Closer
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.
