Promaster 70379 77mm Protection Filter - Basis

Put this on my 77mm lens and it’s so thin I barely notice it’s there. The glass is clear and doesn’t affect image quality at all—just peace of mind against dust and scratches.

I was worried about scratching my lens during a dusty hike, but this filter’s 77mm threading fit snugly and hasn’t budged. It’s thin enough that I don’t notice it’s there, and the glass stays clear after a quick wipe. Exactly what I needed for peace of mind.

Screwed this onto my 77mm lens before a dusty hike, and the filter has taken every scratch so the glass underneath stays perfect. It’s thin enough that I don’t get any vignetting, which was my main worry.
