LEE Filters ProGlass IRND 100mm Filter - 6 Stop

The 6-stop filter provides a neutral density of 1.8, which equates to a reduction of light by six full stops.

Yes, it can be used in conjunction with other filters in a 100mm system, but stacking may introduce additional light fall-off or slight color shifts depending on the combination. It is designed to perform optimally on its own.

IRND filters actively block infrared and ultraviolet light, which digital sensors can pick up, leading to cleaner images with more accurate colors. Standard ND filters primarily reduce visible light and may not prevent IR/UV contamination.

Absolutely. Its precise exposure control and color neutrality make it ideal for maintaining desired shutter speeds and aperture settings for cinematic look in various lighting conditions.

Gently brush off loose dust with a soft brush or air blower. For smudges, use a clean microfiber lens cloth lightly dampened with a professional lens cleaning solution. Always clean from the center outwards.

Information regarding specific warranty periods should be obtained directly from the retailer or LEE Filters, as warranty terms can vary by region and vendor.

The filter's primary function is light reduction. While it does not directly impact autofocus mechanisms, significantly reduced light levels in very dark conditions might challenge some camera AF systems. Autofocus is generally not an issue in typical shooting scenarios where this filter is employed.

Ensure the filter is correctly seated in the holder and that the holder is not causing uneven light. Re-check filter for smudges or damage. If the issue persists, verify that the filter is indeed the IRND 6-stop model.

Confirm you are using a 100mm filter holder designed for 2mm thick filters. Check for any debris in the filter holder slots. Do not force the filter; contact your filter holder manufacturer if compatibility issues arise.

Handle the filter by its edges only to prevent fingerprints or scratches on the optical surface. Clean carefully with a microfiber cloth and appropriate lens cleaner. Ensure the filter is clean and free of dust before shooting.
