Promaster 52mm UV HGX Prime

This filter doesn't mess up my lens corrections in Lightroom like some cheaper ones do. The multicoated glass lets the same amount of light through, so I never have to bump up my ISO.

The ground glass on this UV filter is noticeably smoother than the cheap ones I've used before. It blocks UV light perfectly without adding any weird color cast to my shots. Exactly what my lens needed.

Ground and polished glass makes a noticeable difference—images stay sharp even with the filter on. It’s a bit pricier than basic UV filters, but the build quality feels solid for everyday protection.
