The Schneider 138mm Diopter Set allows lenses to focus significantly closer while maintaining image quality and lens character. Available in +½, +1, +2, and +3 strengths, the set provides a simple and effective way to achieve tighter framing, increased magnification, and close-focus shots without changing lenses.

Compatible with 138mm clamp-on systems and matte box-mounted configurations, Schneider diopters are commonly used for commercials, tabletop work, beauty photography, product cinematography, and specialty close-up applications.
