This complete kit includes the RN-82 variable neutral density filter, the RMB4-82 magnetic filter holder, the RBR-82 rotation ring adapter, and the RMBOX protective transport case. Designed for 82 mm lens thread systems, the variable ND filter offers precise light control with smooth, continuous adjustment from 1 to 9 stops of light reduction.

The rotation ring adapter allows for seamless filter orientation adjustments for polarization effects when used with compatible filters. All components feature precision-machined aluminum construction with a black anodized finish for durability and light-tight performance. The included RMBOX protective case offers organized storage and transport with custom foam inserts that securely hold each component. This professional filter system is compatible with various camera systems including DSLRs, mirrorless cameras, and cinema cameras with 82 mm filter threads. The kit addresses the essential needs of videographers requiring reliable light control solutions for outdoor shoots, studio work, and documentary productions where consistent exposure and image quality are critical.
