Neewer Split Diopter 79mm Lens Filter Handheld

The Neewer 79mm Split Diopter Effect Filter brings a classic cinematographic technique into a simple, hands-on accessory. Split diopter effects — where part of the frame is sharply focused while another area softly blurs — have been used in feature films for decades to create tension, visual depth, or to draw the viewer's eye to a specific subject. This filter recreates that look optically, in-camera, without any post-production work. The half-domed design refracts light through one portion of the glass while leaving the other unaffected, producing a distinctive split between sharp and blurred zones that varies depending on how you angle and position the filter relative to your lens.

Constructed from BK7 optical glass, the filter is built to withstand regular handling and delivers clean light transmission without excessive color shifting. The built-in hand grip makes it easy to hold in front of any lens and experiment with angles on the fly, while the 1/4"-20 threaded hole offers a second option for mounting on a compact tripod or articulating arm when you need both hands free. The included pouch and cleaning cloth are practical additions for protecting the glass surface during transport. At 79mm in diameter, the filter is large enough to cover most standard and mid-range telephoto lenses without vignetting, making it a versatile creative tool for portrait, architectural, and editorial photography.
