138mm 1/3 Split Field Diopter

1/3 Split Diopters are an incredible tool that help you enhance depth-of-field. They allow for more of the scene to be in total focus simultaneously with a more focused effect than a regular Split Diopter. These diopters are semi-circular pieces of glass that are mounted in ring form. They can be rotated in a Matte-Box to achieve the desired effect.
