Promaster 40.5mm 保護濾鏡 - Pure Light

You can barely tell it’s on the lens, which is exactly what I wanted for protection without losing image quality. The glass stays clean and doesn’t introduce any flare or haze, even shooting into the sun. Feels solidly built too—not that cheap thin ring you get with some budget filters.

I was pleasantly surprised by how clear the images remain with this filter on—no discernible loss in sharpness. It fits my lens perfectly and gives me peace of mind against dust and scratches.

Was worried about image quality loss with a protective filter, but my shots look just as sharp as without it. The glass is crystal clear and doesn't add any weird reflections.
