Schneider 4.5" 114mm Water White +1 Split-Field Diopter Close-Up Filter

Split-Field Diopter for Selective Magnification

The Schneider 4.5" 114mm Water White +1 Split-Field Diopter is a precision close-up filter designed for photographers who need to magnify only half the frame. Its single diopter element is cut in half and mounted in the ring, allowing closer focus on one side while the other half remains unaffected. This tool suits creative work requiring simultaneous near and far sharpness.

Optical Limits of the Split Design

The +1 magnification strength provides a specific degree of close-focus enhancement on the treated half of the image. Because the diopter covers only part of the frame, the transition between magnified and normal areas creates a fixed optical boundary that cannot be adjusted in camera. Users must compose carefully to align this split with the scene’s depth requirements.

Water White Glass in a Drop-In Mount

Crafted from water white glass, the filter reduces reflections and glare to maintain contrast across the frame. The drop-in format allows quick attachment and removal without threaded rings, speeding up filter changes during a shoot. The solid ring construction protects the precision-cut element while fitting standard 114mm filter holders or matte boxes.
