Frequently Asked Questions
Does the Fusion ONE Protector filter affect image sharpness or color?
No, the filter uses Hoya professional-grade optical glass with 18 layers of Super HMC multi-coating to maintain high light transmission, so image quality remains virtually unchanged.
Is this filter easy to clean?
Yes, the Fusion ONE features water-repellent and stain-resistant coatings that cause water, fingerprints, and smudges to wipe away easily.
Can I leave this filter on my lens permanently?
Yes, the Fusion ONE Protector is designed for permanent use as a front-element shield against scratches, dust, and accidental impact without degrading your images.
Does the low-profile frame cause vignetting?
The low-profile filter frame is engineered to minimize vignetting, making it suitable for use on wide-angle lenses at the 37mm filter size.
What is the difference between a protector filter and a UV filter?
A protector filter is designed purely to physically shield the lens element, while a UV filter also blocks ultraviolet light. In practice, the Fusion ONE Protector primarily serves as a high-quality protective barrier.
