Hoya HD3 Professional UV Filter 55mm

Very protective and means it is safe to stop putting cap on and off camera all the time as that slows you down and you can mislay or lose your cap when out and about; though still use cap for storage.

Good.

Product as described. Arrived quickly. Thanks.

The earlier HD series from Hoya were remarkable. The HD3 more so. I have not tested impact resistance (not unless someone wants to buy me a sample to try😜) but I've have enough experience with a couple of othe HD filters to confirm they resist scratches, fingerprints and dust to a greater degree than an other I've used. If it were just optics Nikon or B+W are just as good. The fingerprint and dust resistance is hard to accept until you have used one of these for a while - stuff just doesn't stick!Modern digital cameras do not need UV filters so completely clear would do just as well. I use these on lenses that are going to be carried about all day without a lens cap. The goal is to prevent contamination of the front lens element. I'm pretty careful so impact protection is a low risk issue -- dust and grime is a bigger concern for me.These filters are not cheap so you want to make a mental evaluation that tractors in the cost of the lens being protected against the cost of the protective filter and the risk of damage.

I've taken several "lab" photos with my Nikon D850 and zoomed in on photographed microtext with and without the Hoya HD3 filter. I cant tell a difference. No optical degradation that I could detect zoomed 800% on a 45Mpixel image. Exactly what you want for lens protection! Per the coatings...I dunno. I have several less expensive filters and they never seem to be a static magnet like these are. So while they may harden the glass and provide excellent optical results, they do tend to attract dust more than any other filter I've tried. Is that a deal breaker? No - I have since purchased several more of them. Highly recommended!
