Nisi 6x6" Clear Filter camera filter

First line of defence

The NiSi 6x6" Clear Filter sits in front of any 6x6 compatible lens or filter holder, shielding the front element from dirt, debris, smudges and accidental impact. It is built for photographers and cinematographers who want protection without altering the optical path. The ultra low colour shift and non-sandwich optical glass preserve the look of every shot. It is not for shooters who need light reduction, polarisation or creative effects from the same slot.

Fits 6x6 filter systems

The filter slides into standard 6x6" square filter holders or matte boxes, leaving the lens threads free for other accessories. Its scratch-resistant, waterproof and oil-resistant coatings make cleaning quick in the field, while the slim frame avoids vignetting on wide-angle lenses. The glass adds no measurable distortion, so focus and exposure stay consistent. It does not replace a dedicated ND, graduated or special-effects filter in the same holder.

Protective vinyl case included

A custom vinyl case ships with the filter, giving a safe place to store the glass when it is not mounted. The case prevents scratches during transport and keeps the surfaces clean between shoots. No additional adapters, cleaning cloths or software licences are supplied. Buyers who want a hard-shell case or a multi-filter wallet will need to source those separately.
