Square CPL filter for 100mm holder

The Urth 86mm circular polariser slots into the brand's 100mm square filter holder via a dedicated rotating adapter. It is built for photographers who need to manage glare and boost saturation while using a square-filter system.

Replaces fixed or front-thread polarisers

A front-mounted CPL forces you to unscrew the filter to rotate it; this design lets you turn the polarising layer independently while the holder stays locked. The jump is worth it when you regularly stack graduated or neutral-density squares and cannot access the filter front.

Limited to 100mm square systems

The rotating adapter only fits Urth's 100mm holder, so it cannot be used on standard screw-in threads or other-width holders. Polarisation effect still varies with sun angle, and the filter cuts roughly two stops of light, which may require exposure compensation.

Questions about this item

Does the 86mm CPL filter thread directly onto my lens or does it slot into the 100mm square holder?

The filter mounts inside the 100mm square holder using the included rotating adapter; it does not screw onto the lens filter thread.

How do I align the CPL filter once it is seated in the 100mm holder?

Rotate the smooth-movement ring on the adapter while viewing through the camera until reflections are minimised and colour saturation peaks.

Will the German SCHOTT glass coating need special cleaning after heavy field use?

Clean the glass with a standard microfibre cloth and lens cleaning fluid; the coating tolerates normal maintenance without degradation.
