Promaster 67mm UV HGX Prime

The individual grinding and polishing really shows in how the glass doesn’t mess with sharpness at all. I’ve had it on my lens for a week now, and I’m genuinely impressed by how invisible the filter is during regular shooting.

I've been using this filter for a few weeks now and the multi-coating really does cut down on reflections, even when shooting directly into sunlight. It threaded onto my lens smoothly and doesn't seem to add any noticeable color cast to my images.

The glass is noticeably smoother than the cheap filters I've used before, and it threads onto my lens without any wobble or binding. I can leave it on all day and not worry about it affecting sharpness or color, which is exactly what I wanted.
