Nisi PL-RF Filmmaker Adapter Kit (drop-in filter)

The NiSi PL-RF Filmmaker Adapter Kit (drop-in filter) connects PL-mount cine lenses to Canon RF-mount cameras and incorporates a versatile drop-in filter system. For professional filmmakers, camera crews and content creators, this PL-to-RF mount adapter makes it easier to use a variety of filters during film and video productions. The design is compatible with the entire NiSi ATHENA PL-mount lens range as well as most other PL-mount lenses. Stainless steel bayonets, a precise mechanical fit and an additional seal at the camera mount complement the filter system for regular use on film sets.

PL-to-RF Mount Adapter for NiSi ATHENA Cine Lenses and Canon Cameras

The NiSi PL-RF drop-in filter adapter enables professional PL-mount cine lenses to be used on camera bodies with a Canon RF mount. It supports all NiSi ATHENA PL-mount lenses and is also compatible with most other PL-mount lenses. Even cine lenses with protruding rear lens elements can be used, as the integrated filter system does not hinder their movement during focusing. This is particularly important for lens designs with moving rear elements. The precision-machined mounting surfaces ensure a stable connection between the lens, the adapter and the camera body. This reduces unwanted mechanical play, which facilitates controlled focus shifts and working with follow-focus systems. The PL-to-RF mount adapter is suitable for digital cinema productions, documentaries, commercial shoots and professional YouTube video productions. Weighing around 207 g without a filter fitted, the adapter remains compact and can be integrated into various camera rigs. For camera crews using multiple PL-mount cine lenses, the positioning of the filter system on the camera mount offers a practical advantage, as the filter can be used independently of whichever lens is currently fitted.

Drop-in filter system for ND filters, CPL and controlled film looks

The integrated drop-in filter system supports the NiSi ATHENA filter series and allows different filter types to be used directly between the lens and the camera body. Compatible filters include True Colour VND, True Colour CPL, Black Mist and FS ND. Filters can be changed on the adapter without having to remove the cine lens from the camera. Variable ND filters make it easier to control exposure in changing light conditions and allow for consistent aperture and shutter speed settings. CPL filters can reduce reflections on non-metallic surfaces and influence the rendering of certain colours. Black Mist filters produce a softer rendering of bright areas of the image and support a distinctive cinematic look. This makes the drop-in filter system ideal for interviews, narrative film productions and shoots in varying lighting conditions. Compatible VND and CPL filters can also be adjusted via a wireless lens control motor with a 0.8-MOD gear drive. This feature facilitates controlled filter adjustments whilst filming, for example during camera movements or in changing lighting conditions. The adapter’s design also takes into account the optical changes caused by the drop-in filters used. This ensures that the infinity focus is maintained on compatible lenses, which is particularly important for landscape photography and distant subjects.

Stainless steel bayonets and weather-sealed construction for professional film shoots

The NiSi PL-RF Filmmaker Adapter Kit (Drop-In Filters) uses 304 stainless steel for both the lens-side and camera-side mounts. This material combines high mechanical strength with corrosion resistance and is suitable for camera equipment that is regularly mounted and dismounted. The robust bayonets ensure a reliable connection between the PL-mount lens and the Canon RF-mount camera. An additional seal on the camera-side mount helps to reduce the ingress of dust and moisture around the connection. This offers additional protection during outdoor shoots, but does not replace a fully weather-sealed camera system. The precise mechanical construction minimises unwanted movement between the connected components and ensures the lens sits securely. This design is particularly advantageous for professional camera rigs, shoulder mounts and frequent lens changes. Weighing approximately 207 g without a filter, the adapter is also suitable for mobile film productions. For filmmakers and content creators, the system combines a robust mechanical design with the ability to flexibly integrate various ATHENA drop-in filters into the filming process. This allows existing PL-mount lenses to be used on compatible Canon RF-mount cameras for a variety of film projects.
