Promaster 6606 67mm 保護 HGX Prime 濾鏡

Took this filter out in dusty conditions and it kept my front element spotless without any noticeable drop in image quality. The glass is clear and it threads on smoothly, no annoying tight spots.

I mounted this on my 24-70mm and instantly noticed how little it affects the final image compared to cheaper filters. The multi-coating makes cleaning off smudges effortless, and it hasn't caused any flare issues even in direct sun. A solid investment for keeping the front element safe without sacri

Put it on my 24-70mm f/2.8 and the HGX Prime coating repels dust and smudges way better than my old cheap filter did. Image quality is totally unchanged, which is exactly what I wanted for lens protection.
