HoyaHD3 82mm UV Protector Filter - Re-Certified for 100MP+ Cameras with Ultra-Hard Nano Coating UV Filter - Stain Resistant, Smudge and Waterproof UV Lens Filter with Aluminum Frame

Optically neutral with no image degradation at any point. Protects expensive objective lens. Perfectly made screw threads that don't bind like other brands. Easy to clean. Automatic purchase for every new lens.

I use it to protect a 16-35 f2.8 Sony GM lens and don’t use lens caps or hoods. Stays clean, doesn’t degrade image quality, and is tough. Expensive but worth it to protect a valuable lens.

Great quality product and reasonable!

C'est le meilleur filtre UV du moment. Certes il est très cher, mais quand on aime on ne compte pas.

It is maybe good optically and hard coating. Buy it attracts dust easily and is very hard to clean. Once you cleaned….in 10 minutes it is dusty again. Returned.

Everything is good to perfect but overpriced evenmore than Sigma Ceramic filter!

This is a good quality filter. As usual you get what you pay for.

From all the reviews, this is the best available
