Promaster 77mm Protection Filter - Pure Light

I was worried a filter would soften my images, but this one is completely invisible in the final shots while still guarding the front element from spray and dust. The glass is crystal clear and it threads on smoothly without any vignetting at 77mm.

Kept it on my lens during a dusty beach shoot and didn't have to wipe a single speck off the glass afterward. The clarity is completely untouched, which is exactly what I wanted from a protection filter.

I’ve had this 77mm filter on my main lens for a few weeks now, and the coating really does keep dust and fingerprints off without smudging. The glass is so clear that even shooting directly into sunlight, I haven’t noticed any haze or color shift in my images.
