Promaster 77mm UV HGX Prime

Put this on my 24-70mm and noticed immediately how much richer the colors looked through the viewfinder. The ground and polished glass feels noticeably thicker than my old cheap filter. A solid upgrade that doesn't mess with sharpness at all.

The individual grinding and polishing on this filter really shows—no distortion even with my wide-angle lens. It sits flush and doesn’t add any noticeable color cast to my shots.

I've been using this on my 70-200mm and the image quality is noticeably sharper than my old UV filter. The multi-coating seems to cut flare really well in bright sun.
