Hoya NXT Plus 58mm 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

Excellent product in every way.

Very good quality.

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 filter is great for my intended purpose. Nicely made. But what was Amazon thinking when they dropped it in an 8x10 bubble mailer? The case was destroyed. I haven’t decided if I’m going to send it back yet. But jeez Amazon, try harder.

Super scratch resistant and perfect for my Tamron lens

I love the Hoya NXT Plus filters and they give me great results. But the reason I am writing this review is because I witnessed the Amazon truck involved in an accident close to my location. I thought my deliveries might be on that truck and they were. I was expecting to hear that the delivery was going to be delayed, but it wasn't. The delivery still made it to me with only a few hours delay. That was above expectations!

Super fast shipping, it is a thin circular polarizer and it works great

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.
