The Schneider Diopter - 95mm is a high-quality, screw-in optical accessory designed to boost the close-focusing capabilities of professional cinema lenses. Crafted from premium-grade optical glass and multi-coated for superior light transmission, this diopter enables cinematographers to capture extreme close-ups with remarkable detail, preserving sharpness, contrast, and color accuracy. Diopters act as high-quality convex magnifiers, reducing a lens's minimum focus distance without altering its inherent optical characteristics. Unlike dedicated macro lenses, they retain field of view and perspective but introduce a shallower depth of field, demanding precise focus control. Higher-powered diopters may cause slight edge softness or field curvature, but when used correctly, they offer a seamless path to achieve macro-level cinematography without lens changes.
