Kipon has announced its new PL Variable ND adapter, available in Sony E and Nikon Z mount versions. Designed for owner/operators looking to pair compact mirrorless cameras with professional PL mount cinema lenses, the adapter integrates a continuously variable neutral density system directly into the mount, offering a streamlined alternative to front-mounted filters and other external filtration solutions.
Integrated ND adapters are nothing new, with products like the Fotodiox ND Throttle, Metabones eND adapters, KipperTie’s Revolva system, and even electronic ND solutions built into cameras from Sony and RED all tackling exposure control in different ways. Kipon’s announcement is less about introducing a new concept and more about offering its own take on the idea, with an emphasis on PL mount compatibility and professional cinema workflows.
Designed for PL Cinema Lenses
According to Kipon, one of the primary engineering challenges was accommodating PL lenses with protruding rear optical groups. The company says it developed a “deep-recessed Variable ND architecture,” positioning the ND module as deep within the adapter body as possible to maximize lens compatibility.
The adapter also incorporates a precision multi-start threaded mechanism for flange focal distance adjustment. While this feature may go unnoticed by many users, precise flange focal distance is critical when working with PL mount cinema lenses, where maintaining accurate back focus is essential.
For owner/operators using mirrorless cameras, integrating the variable ND directly into the adapter can simplify a camera build. Instead of relying on front-mounted variable ND filters or dedicating space to a matte box and filter trays, exposure can be adjusted directly at the lens mount while leaving the front of the lens free for other accessories.
Japanese Design and Manufacturing
Kipon is placing significant emphasis on the adapter’s origins. The company says this is its first flagship cinema product to be designed and assembled in Japan using a Japanese optical supply chain.
For a manufacturer whose catalog has historically consisted of products manufactured in China, the move represents a notable shift. Japanese optical manufacturing continues to carry a strong reputation for precision and consistency, making it understandable why Kipon chose to highlight this aspect of the announcement.
Kipon also says the Variable ND module is manufactured in Japan and is designed to deliver excellent optical flatness, color consistency, and long-term reliability. As with any variable ND system, however, independent real-world testing will ultimately determine how well those claims translate into production use.
Noteworthy Technical Omissions
One notable omission from the announcement is Canon RF. Given the popularity of RF mount cameras among owner/operators adapting PL cinema lenses, the absence of an RF version is somewhat surprising.
Similar PL-to-RF variable ND adapters already exist on the market, suggesting the omission is not due to an inherent technical limitation of the RF mount. Kipon has not addressed why Sony E and Nikon Z were chosen while RF was left out, so Canon users will have to look elsewhere for the time being.
One notable omission from the announcement is the adapter’s variable ND range. For cinematographers evaluating an internal ND solution, knowing the usable density range is a fundamental specification. Real-world testing will also be needed to evaluate color accuracy, consistency, and overall optical performance.
Pricing and Availability
The Kipon PL Variable ND adapter will be available in Sony E and Nikon Z mount versions beginning in mid-August 2026 with an MSRP of $699 USD.
Kipon is also offering a 15% bundle discount when the adapter is purchased together with its Mamiya645-PL 0.7x Optical Focal Reducer, allowing cinematographers to pair medium format Mamiya 645 lenses with integrated variable ND using Kipon’s optical focal reducer.
