Schneider 6in round +1 diopter filter, optical glass with anti-reflective coating

SCHNEIDER

SCHNEIDER 6in Round +1 Full Field Diopter Lens 68-071060

SKU CH-AFPP-4SW52

A 6-inch full-field diopter lens with +1 strength and multi-coated optical glass for closer focus from greater distance

  • +1 diopter extends close-focus range from greater distance
  • Multi-coated optical glass cuts flare and preserves colour contrast
  • 4 mm diameter fits large-format matte boxes and rigs
  • Brass mounting rings give secure, repeatable attachment
  • Hard anti-reflective coating on both surfaces maintains image quality

Purpose and fit

This Schneider full-field diopter lens adds a +1 optical grade to a camera system, letting the operator focus closer without changing the prime lens. It suits cinematographers and photographers who need a lightweight way to reduce minimum working distance on set or location. The 6 inch round format matches large-diameter matte boxes or direct barrel mounting on compatible lenses.

Build and mounting

Optical glass construction is paired with multi-coated surfaces on both sides to cut flare and preserve contrast. Brass mounting rings on the screw-on version provide a durable, corrosion-resistant thread that withstands repeated attachment cycles. The unique mounting technique locks the element securely, maintaining alignment even under vibration or temperature swings during production.

Optical limits

Strength depends on the host lens focal length, focus setting, object distance and size, so the exact close-focus gain varies from shot to shot. The +1 grade delivers a moderate shift; users requiring stronger magnification will need a higher-grade diopter or a different close-up solution. No electronic contacts or autofocus coupling are present, so exposure and focus remain fully manual.

Questions about this item

What does the +1 diopter grade mean for focus distance?

The +1 grade lets the lens focus closer than its normal minimum distance while keeping the camera farther from the subject; exact shift depends on the taking lens focal length and focus setting.

What thread or mount does the 152.4 mm filter use?

The screw-on version ships with brass mounting rings that thread onto the front of the taking lens; drop-in versions use black anodized aluminum rings for matte-box trays.

How do I install the filter without damaging the coating?

Handle by the brass or aluminum ring only, align threads carefully, and turn until snug — forcing the glass or cross-threading the ring is the common mistake that mars the multi-coated surfaces.
