Urth 39mm Variable ND2 32 + CPL Filter Pro

Urth 39mm Variable ND2 32 + CPL Filter Pro

The Urth 39mm Variable ND2 32 + CPL Filter Pro combines variable light reduction with polarisation in a single filter, for controlled exposure and reduced glare in bright, complex lighting.

Highlights

• 1-5 stop light reduction with integrated polarisation
• Premium SCHOTT B270 optical glass
• CoraNano™ Max 34 layer dual side nano coating
• True Color transmission without unnatural casts
• Ultra low ≤0.5% reflectance against ghosting and flare
• Ultra slim aluminium frame to prevent vignetting

The Pro line up

Urth's Pro line up stands for professional exposure control without compromise. The filters are built around German SCHOTT B270 glass and Urth's CoraNano™ Max 34 layer dual side nano coating, with ultra low reflectance for maximum clarity. A warp resistant aerospace grade frame and ergonomic, precise operation make the range suited to demanding work.

Exposure and polarisation in one

This filter controls 1 to 5 stops of light reduction and adds full polarisation on top. That keeps exposure balanced in bright light while suppressing reflections and glare, ideal for complex lighting situations.

Image quality and True Color

The German SCHOTT B270 glass and 34 layer CoraNano™ Max coating deliver sharp, clear images. True Color transmission prevents unnatural colour casts, while the ultra low ≤0.5% reflectance keeps ghosting and flare out of frame.

Operation and build

Smooth, precise rotation with tuned resistance and a hard stop design makes fine tuning easy. The ultra slim 6061 aerospace grade aluminium frame limits vignetting, even on wide angle lenses.
