Lindsey Optics Rota-Split Diopter Close-Up Lens 50% (4×5)

This unique close-up lens is a 138mm +1 diopter that has been cut in half and mounted in a geared rotating tray for quick and easy alignment of the split line. Split field diopters 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 tray. 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.

The Rota-Split geared rotating tray makes it easy to quickly get perfect alignment of the lens edge. Additionally, Brilliant² Rota-Split filters have a Broadband Multi-Layer Anti-Reflection Coating (MC Coating) that reduces reflections from the lens preventing unwanted ghost images and reducing stray light and flare.
