82mm Screw-In Close Up Diopter

Get closer to your subject without sacrificing optical performance. The Revar Cine 82mm Screw-In Close-Up Diopter greatly improves your lens’s close-focus capability, opening up tighter framing and detailed close-ups with spherical and anamorphic lenses. Made with the same professional-quality optical glass as our 138mm cinema diopters, the 82mm version brings that quality to today’s more compact cinema and photography setups. Precision-polished Schott B270 glass and broadband anti-reflective coatings deliver significantly higher optical quality than inexpensive close-up diopters. Screw it directly onto a lens with standard 82mm front filter threads, or use a step-up ring to fit lenses with smaller filter threads. Key Features Closer Focus: Capture tighter shots and fine details beyond your lens’s native close-focus capability. Professional Optical Glass: Precision-polished Schott B270 glass provides the same glass quality as our 138mm cinema diopters in a compact screw-in format. Broadband Anti-Reflective Coatings: Help minimize unwanted reflections and preserve image contrast and color fidelity. Ideal for Anamorphic Lenses: Expand close-focus options for lenses with long minimum focus distances. Direct Lens Mounting: Fits standard 82mm front filter threads without requiring a matte box or separate filter tray. Adaptable to Smaller Lenses: Compatible with smaller filter-thread sizes using an appropriately sized step-up ring. Full and Split Options: Choose a full diopter for close-ups across the frame or the +2 split diopter for compositions combining near and distant subjects. Understanding Diopter Strengths and Infinity Focus Higher diopter strengths bring the available focus range closer to the camera. The distances below apply when your lens is set to infinity—not to its minimum focus setting. They represent the approximate farthest focus distance with a full diopter attached, measured from the diopter: +0.50: Approximately 2 meters (6.6 feet). +1: Approximately 1 meter (3.3 feet). +2: Approximately 0.5 meter (1.6 feet). A full diopter prevents your lens from focusing at infinity while it is attached. For example, a +2 diopter brings a lens set to infinity into focus at approximately 0.5 meter from the diopter. Turning your lens toward its minimum focus setting brings focus closer still, greatly improving close-focus capability. The actual minimum focus distance varies with your lens’s native close-focus ability and optical design. Because lens focus distances are generally measured from the camera’s sensor plane, the distance between the front-mounted diopter and the sensor also affects the focus distance measured from the camera. These figures are a starting point; check focus with your specific lens and camera setup. 82mm +2 Split Diopter The Revar Cine 82mm +2 Screw-In Split Diopter places close-up glass over one half of the opening while leaving the other half unobstructed. This allows you to bring a foreground subject into focus through the diopter while retaining your lens’s normal focus range—including infinity—through the uncovered half. Unlike a full diopter, the split version creates two distinct focus zones within the same image. It is a creative tool for compositions that keep a nearby subject and a distant subject sharp simultaneously, without relying solely on stopping down the lens. The +2 half follows the same approximate infinity-setting focus distance of 0.5 meter (1.6 feet) from the di
