HoyaNXT Plus 67mm Polarizing Filter — Circular Polarizer with Waterproof Top-Coat, 10-Layer HMC Coatings, 1.72 Filter Factor for Faster AF, Low-Profile Aluminum Frame for Outdoor Photography

I get so tired of trying to sort through conflicting reviews on things and trying to pick out a new circular polarizer for my new Sony rx10 Mark 4 was getting frustrating. I finally picked this unit, especially for its low profile construction and threads on both sides. It will indeed fit onto the Sony's lens and yet still allow you to install the factory lens hood and lens cap. And yes, if you are careful with your finger, you can reach in around the lens Hood and press on the grippy ridges of the front edge of this polarizer to rotate it without putting a fingerprint on the filter. Yes you have to be careful but it does work nicely. I have been a photographer for a long time, since the early 80s, and have used many cameras with different polarizers. I decided against a 'warming' polarizer because now with digital photography, color adjustments can all be done in software after the fact. The polarization effect is beautiful and quite noticeable and I do not notice much added lens flare artifacts. The multicoating seems to be doing its job. There is no vignetting with the Sony rx10 Mark 4 at its widest lens magnification setting. And finally, there are enough threads on the front of this filter for the factory pinch grip lens cap to fit securely.I do not use this with a UV filter. I think that is unnecessary. I use the polarizer directly on the front of the lens as needed. Let me share a couple of secrets to make this polarizer more useful: 1) Absolutely do NOT screw this on tightly to your lens, which will cause it to jam. You will see this happening to people over and over with screw-on filters. It's very simple: only screw it on lightly until it just stops turning. Do not tighten it! After that, no worries. It always comes off easily, thanks to the nice grooving on the outside diameter. 2) With the filter off of the camera, find the white triangle index mark on the outside diameter. Use a small file to grind off a tiny portion of the black finish on the front facing part of the rotating polarizer, adjacent to the index mark (see photo). Tip: the index mark is the spot that lets you know which way the polarizer effect is oriented. You point this generally toward the sun position to darken the sky when looking 90° from the sun. Or you set the index point to top center to block reflections from horizontal objects like water. Or you can just spin it around and look through your viewfinder until you achieve the effect you desire for foliage, clouds or other compositions. The trick is to be able to see the index mark from the front while still using the lens hood, which prevents you from grabbing the outside of the rotating portion of the filter normally. The serrations on the front of this filter, visible in the photo, let you turn it by touching it with your finger from the front, and with your new shiny index mark visible from the front, you are all set and will not have to remove your lens hood to make adjustments. Super convenient!

This review is for the Hoya 67mm NXT Plus UV HMC Multi-Coated Slim Frame Glass Filter, which I have recently purchased.There are much cheaper filters out there, and there are more expensive filters. If you have a low quality lens, then you may not want to spend this much on a UV filter, but you definitely do not want to put a cheap filter on a good piece of glass.I do not think I have owned a better UV filter, so I do not mind spending a little more on it. I was so impressed after using this new NXT Plus model for a while that I immediately bought another one for another lens. I have seen no distortion or colorization with this filter, and there is virtually no ghosting, because of the great multi-coating they use. And having the waterproof top coat does make it easy to keep clean.I would highly recommend these UV filters.

Only recently did I discover my cheap (under $10) UV filters could catch a light at a certain angle which would cause flare on my images. I still support the idea of having a protective glass lens so rather than leave my lens naked I decided to try a better, recommended by users, filter.This Hoya was a great improvement but I could still find situations where there would still be flare in my images. Removing the UV filter I could not see any flare so it wasn't the lens.Two of my lenses are 67mm filter size. On the 85mm lens the Hoya gave the results mentioned above. On the 16mm lens I could not see any flare with or without the filter.This is a controversial topic. My position is a UV filter can help prevent dust and moisture finding it's way into the lens. It also protects the lens from scratches. I will continue to use UV filters. Only under certain light conditions do my lenses show flare. If I see flare in one of those cases I can simply shift angles to eliminate the flare, or in critical situations simply remove the filter. Most of my lenses cost between $500 and $1000 so I'm very concerned about keeping them pristine.

Clearly a high-quality product. I use it on a Fujifilm medium format lens and the GFX 100 camera (100 MP) and any flaw would be immediately noticeable. But, I see no flaws, and the depth of colors and reduced “popping” of hot spots from bright sun are immediately noticeable in the form of much more pleasing outdoor photos. I also have water (mostly rivers) in many pictures I’ve taken with this filter and the reduced glare is also a big plus. I rate value lower only because these aren’t cheap.

As a serious photographer, filters are an important tool in your camera bag. To most, UV filters "are just a thing to cover your front lens element"...well, they're more than that. They must be of the most high quality as possible, as you frequently place polarizers and neutral density filters in front of it. I use only Hoya NXT Plus filters on my Canon L lenses. The quality is superb and the price is right.

Great filter that holds up well in the field. Thinner than most and fits in case better than standard. Glass quality is excellent-no issues or aberrations ever from this mfg. You pay more than others but the quality is well worth it.

I purchased a few of these UV filters to protect the end of a few of my lenses. I typically install UV filters permanently on all my lenses to protect the end of the lens from getting scratched or damaged. These were replacements for the Gobe UV filters I purchased a while back, as I wasn't too impressed the the clarity of the Gobe UV filters, I have no complains about their ND or CPL filters, just their UV filters. These seem to be much better than the Gobe's and hopefully they'll last a while.

Good fit, easy to remove if not over tightened. A little pricey for this range of CPL glass. To note that this lens reduce about 2-stop in exposure.
