FAQ

Question: Will this filter cause vignetting on wide-angle lenses?

Answer: The filter features an ultra-thin 3.5mm frame specifically to minimize vignetting on wide-angle lenses. However, compatibility depends on your lens design and any additional filters or adapters you stack; check your lens thread and test to confirm.

Question: How does the Nano coating affect image quality?

Answer: The NiSi Pro Nano HUC has nano coatings on both sides and a low-reflection surface (0.3% reflection). These properties help maintain high light transmission (>99.3%) and preserve contrast, while also making the surface easier to clean.

Question: Is the filter easy to clean and maintain?

Answer: Yes. The filter has a hardened waterproof coating and nano treatments that simplify cleaning and resist water. Additionally, the superfine dull polishing and knurling on the frame reduce visible wear from repeated rotation.

Question: How do I confirm this filter fits my lens?

Answer: Check your lens filter thread diameter and match it to the 72mm size of this NiSi filter. If you are unsure about compatibility with your lens model, contact us and we will help verify fitment or source the correct size.
