Promaster 43mm Protection Filter - Pure Light

The coating is so clear I honestly forgot the filter was on the lens—zero impact on image quality. Took a few accidental knocks on a hiking trip and the glass held up perfectly without any scratches.

Installed this on my walkaround lens and it doesn't add any weird color cast to daylight shots. The glass is clear enough that I forget it's there, and it's already saved the front element from a stray fingerprint.

I've been using this on my vintage lens and it's completely invisible in shots—no added haze or loss of sharpness. The multi-coating really does its job keeping reflections at bay.
