The SmallRig 5894 CPL/VND3-5 filter has been specifically designed for the DJI Osmo Action 6 action camera and offers enhanced optical control for outdoor videography. This dual-function filter combines a circular polarizer (CPL) with a variable neutral density component (VND), allowing for adjustable light reduction of 3 to 5 stops. The CPL element effectively reduces glare and reflections from non-metallic surfaces such as water and glass while increasing color saturation and contrast—especially useful for capturing vibrant outdoor scenes. The VND component enables precise exposure control by reducing incoming light without compromising color balance, achieving optimal shutter speeds for smooth motion shots even in bright conditions. Made from high-quality optical glass with multi-layer nano-coating technology, this filter maintains excellent light transmission while minimizing ghosting and lens flares. The aluminum alloy frame features a slim profile that prevents vignetting with wide-angle lenses and includes a ribbed edge for easy rotation adjustments. With precise threading, it ensures a secure fit on the DJI Osmo Action 6 camera housing and maintains the camera's waterproofing when installed correctly. The filter measures approximately 49 mm in diameter with a thickness of 5 mm and weighs around 25 g. It is ideal for action sports enthusiasts, travel videographers, and outdoor content creators who need professional light control without compromising the compact form factor of their action camera setup.
