The Revar Cine 138mm +2 / 52mm Compression Diopter is a professional special-effects filter designed to create subtle selective focus, edge distortion, and spatial compression in-camera.

IMPORTANT: This is a special-effects filter—not a conventional close-up diopter. It creates a stylized image with a sharp central area and progressively altered focus toward the edges. Buyers seeking a standard full-frame close-up diopter should choose a different product.

The 52mm flat center window preserves a defined central image area while the surrounding +2 diopter glass gently modifies focus and perspective toward the edges of the frame. This subtle effect can draw attention to a face, product, or other central subject while adding controlled softness and visual separation to the surrounding image.

Condition:

Open-box filter in like-new condition. Includes a protective pouch and a one-year warranty.

Key Features:

• +2 compression-diopter strength
• Professional 138mm cinema special-effects filter
• 52mm flat center window
• Subtle selective-focus and edge-softening effect
• Smooth transition from the clear center into the surrounding diopter area
• Made from Schott B270 optical glass
• High-transmission coating helps preserve color fidelity and minimize reflections
• Compatible with matte boxes and filter holders that accept standard 138mm filters

Lens Compatibility:

The 52mm center window works best with lenses having approximately 95mm to 120mm front diameters. Compatibility alone does not guarantee a particular visual result.

The exact effect will vary according to:

• Camera sensor size
• Lens and front-element diameter
• Focal length
• Focus distance
• Aperture
• Position of the filter relative to the lens
• Matte box or filter-holder configuration

Testing with the intended camera and lens combination is recommended before production. Wider lenses, larger sensors, and different front-element sizes may reveal more of the transition between the flat center window and the surrounding diopter glass.

This listing includes one Revar Cine 138mm +0.50 Compression Diopter with a 52mm center window and protective pouch. No other filters are included.
