Hoya HD3 58mm 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

Perfect

I plan to use two filters at the front end of my Canon binoculars. The Canon optics filter an unspecified amount of UV, but since they concentrate whatever comes into the front lens I take a belt-and-suspenders approach.The two filters I tested are listed in the headline. Both filters are double-threaded and neither noticably blocks visible light.Using a UV meter, I first took a reading of a bright part of the sky, which comes in at 2190 micro-Watt / cm^2. Next I place the filter over the meter, trying to keep it steady. I did this three times for each filter.The Hoya is a bit more expensive, but it blocks 12x as much UV as the B+W filter (55 vs. 660 micro-W/cm^2). So for my purpose the Hoya filter seems much preferable.

After reading Ken Rockwell's review of the Nikon Zf mirrorless camera and his recommendation to also purchase a Hoya HD3 Professional UV Lens Filter, I purchased both. The Hoya HD3 is a sturdy, well-made lens filter that provides extra protection against finger prints, smudges, moisture and minor scratches. It also seems to stay cleaner than my other lens filters. As a result I've purchased Hoya HD3's for all of the new "Z" lenses that I've bought for my new Zf camera and I'm pleased with all of them. Hoya HD3's cost more than other filters, but they appear to be definitely worth it... especially for $1,000+ Nikkor and Voigtlander lenses I highly recommend Hoya HD3 lens filter for your valuable - and not so valuable - lenses.

Hoya is always a brand I trust for filters. Although The HD3 is expensive it is the best. I have never had any issues with Hoya. If you purchase expensive glass for your camera you don’t want to put a cheap low guality filter on it.

Are you kidding me? I put this into a super filtered studio of mine and I mean almost no dust and the filter sucks dust up from - what seems like - all corners of the studio. Oh MY GOD. You guys really are sloppy. Also - just an FYI - your antistatic filters (EVO) all come with a cloud of dust on the lens right out of the little box with the static charged foam you lazily slop the filter on top of so it can bang around during shipping.We use seriously high-end cameras and this blows my mind that you - after all these years of manufacturing - are so sloppy. Fix the static problem and package your stuff right - the reason you have good reviews as well is because they people posting them don't check anything and are green - anybody who inspects this hd3 lens will watch dust collect and - no matter what - blower/anti-static brush/pancro with kim wipes - etc - the dust just keeps on coming back.

High quality glass and threads. Used it on an assignment in Everglades with an 18-135mm zoom. No distortion no vignetting.

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.

Great product. I ordered the wrong size and returned it for the correct one.
