The Tiffen 138mm Diopter Set allows lenses to focus closer while preserving their native optical character. Available in +1/8, +1/4, +1/2, +1, +2, and +3 strengths, the set offers a wide range of close-focus options, from subtle reductions in minimum focus distance to high-magnification close-up work.

Compatible with 138mm clamp-on systems and matte box-mounted configurations, Tiffen diopters are widely used for commercials, beauty work, tabletop cinematography, product films, and specialty macro-style shots where additional close focus is required.
