For 4 × 5.65-Inch Matte Boxes. The 4 × 5.6 Lindsey Optics +1/2 Diopter Rota-Split 50% Filter fits into most professional 4 × 5.65-inch cine matte boxes using a single slot.

Rotating 50% Split-Field Filter. Split field close-up lenses are used to create dramatic near/far effects in a scene. The near object is seen through the 50% cut lens and the more distant objects are imaged through the blank space in the filter. The cut edge of the lens is usually aligned with an edge in the scene such as a table edge, a door frame, building edge or a tree trunk. This hides the transition line and creates a seamless near/far effect.

Designed for Convenience. This filter is cut in half and mounted in a geared rotating tray for quick, easy, and accurate alignment of the split line.

Anti-Reflection Coating. Lindsey Optics Rota-Split filters have a Broadband Multi-Layer Anti-Reflection Coating (MC Coating) that reduces reflections from the lens and prevents unwanted ghosting and flare.

Available in Other Values. We also carry this filter in the +1/4 and +1 values, which use one matte-box slot, the +2 value, which uses two slots, and the +3 value, which uses three slots.
