Promaster 67mm Protection Filter - HGX Prime

I’ve been using this filter on my 67mm lens and the image quality is exactly the same as without it, which is exactly what I wanted. The prime optical construction really does keep things crystal clear.

I was worried a filter would add glare, but this one is so clear I honestly can't tell it's on the lens. The 67mm threads screwed on smoothly without any binding.

The HGX Prime's multi-coating is noticeably better than cheaper filters I've tried — no weird reflections or color shifts, even shooting into the sun. It's thin enough that my lens cap still fits perfectly, which was my main worry.
