Full details

FAQs
Can I use this filter on any lens?
Yes, provided you have a 100mm filter holder system and the correct step-up or adapter ring for your specific lens thread size.
What is a 4-stop reduction useful for?
It is perfect for bright daylight shooting where you want to blur motion (like waterfalls) or use a wide aperture to achieve shallow depth of field without overexposing the image.
Does this filter cause a color cast?
No, the filter is designed with a consistent transmission curve to ensure neutral color reproduction.
How do I protect the filter when not in use?
Store the filter in a protective padded case or the provided pouch, ensuring it is kept away from hard objects that could scratch the glass.
Can I stack multiple filters with this?
Most 100mm holder systems allow for stacking multiple filters; however, stacking too many may increase the risk of vignetting on ultra-wide lenses.
Troubleshooting
Visible light leaks around the filter edges
Ensure the filter is pushed fully into the holder slot and check that the foam light-seal gasket on your holder is not damaged.
Image appears soft or blurry
Verify that the filter surface is clean and free of fingerprints or smudges; also ensure the filter is sitting flush in the holder.
Pros and Cons

- Effective protection against moisture and smudges with nano-coating

Setup, Compatibility & Care
To use this filter, you must first attach a 100mm square filter holder to your lens using the appropriate adapter ring for your lens diameter. Once the holder is locked in place, gently slide the 100x100mm filter into the slot. Always ensure the glass is clean before insertion to avoid scratching. To clean the filter, use a high-quality microfiber cloth or a dedicated lens cleaning pen. If the filter encounters salt water or heavy dust, rinse it lightly with distilled water and dry it gently to maintain the integrity of the 20-layer coating.
