Revar Cine 138mm / 52mm Close-Up Compression Diopter +0.50

The 138mm, +0.50 Compression Close-Up Diopter from Revar Cine has a precision-polished flat 52mm center window. Draw selective focus to the center of your frame while leaving the outside of the frame with spherical distortion. The clear center window allows for a smooth transition to better hide the effect transition in the camera.

• High-quality anodized aluminum ring with scratch-resistant coatings.
• The 138mm filter allows for the use of wide-angle lenses for maximum compatibility.
• The 52mm clear center flat window in the center of the diopter creates selective focus.
• It offers a Kaleidoscope effect in the common professional 138mm size.
• This specialty filter creates a zoom rack-type effect where the edges of the image are blurred, and the center flat window retains the in-focus image.
• It comprises a high-quality Schott BK7 glass with an index similar to your lens elements.
