NiSi, 49mm UHC UV Protection Filter – Ultra-Slim Design with 18 Multi-Layer Coatings, Ultra Hard Coating, Nano Coating, Hydrophobic & Scratch Resistant – UHD Clarity and UV Filter for 49mm Camera Lens

They dropped my lens at customs (RIP calm nerves), and while the NiSi filter shattered, my lens came out completely unharmed—which is exactly what this thing is meant to do. The ultra-slim design didn’t cause any vignetting, and the coatings kept it crystal clear while it lasted. Hydrophobic, scratch-resistant, and apparently impact-sacrificial. Honestly? It died a noble death. Ordering another.

Perfect fit and barely noticable

The Nisi 82mm UV protection filter does everything it should. I use it on my Canon 24-70mm lens and it protects the lens nicely while not causing any issues with color. It screws on easily. I will definitely by one for the new lens I am getting because it's great quality for the money.

I needed a UV filter for my new Viltrox 75mm F1.2 PRO, and found that my usual brand (B+W) has gotten kind of pricey. So I decided to try this NiSi. I have to say I'm impressed at the premium feel and clarity of the glass. Even the packaging was nice.The knurled edges will make this easy to remove down the road. I've only taken a few test shots with it on, but I can already tell this is a keeper. People debate whether UV filters are even necessary, but I consider them a small investment to protect the larger investment of a quality lens.

This is a review of the NiSi UHC UV Protection Filter, in 46mm, with an ASIN of B0BM79ZL4Z.Short version (TL;DR) - Negative: Green lens flare artifact. Neutral: Same big case for all sizes. Positives: Sturdy. Smudge-resistant. Nicely machined. Lens cap compatible.Long version …As my title is quite the spoiler, I should probably address that directly. In situations where I had intense lens flares - i.e. shooting toward the sun at sunset, a significant green artifact appeared in the lens flares. This doesn’t happen with my hardware without this filter, so I think it’s a solid bet that the filter is at least contributing to the issue, if not creating it outright. Anyway …Negative:* Green Lens Flare Artifact - as noted above, this appears to introduce a green artifact to intense lens flares. I’m including a sunset picture that demonstrates what I’m talking about. The effect doesn’t appear to occur with less intense lens flares, it’s worth noting.Neutral:* One Fixed Case Size - for the larger filter sizes, this won’t be as comical as it was for this one, but the wee little 46mm filter I’m using came in a case that absolutely dwarfed it. This isn’t a pro or a con, but I found it humorous enough to mention.Positives:* Sturdy - this has taken a few hits it shouldn’t have, but I’m quite happy they were to it and not to my lens. As yet, there’s not a mark on it. I’m favorably impressed in that regard.* Smudge-resistant - more than a few times I’ve reached for the camera, thinking I had the lens cap on it, and, instead, gotten a nice firm grip right across this filter. On other occasions, I’ve moved around too quickly in tight spaces with the camera on a tripod, catching my ear, nose, or hair on the filter (in place of the lens). This has rarely left any kind of trace at all. They really don’t seem to be kidding about the oleophobic (oil-hating) coatings et al.* Nicely Machined - this has very well made grip ridges around much of its circumference and is generally very nicely made. Unlike certain other filters (which shall remain nameless), I’ve had no issues getting a solid grasp on this when I need to.* Lens Cap Compatible - despite being rather thin, this filter will still let a lens cap get a good grip on it. I realize that for many people this won’t matter, but I’m the kind of weirdo that still generally caps things when not actively shooting.In general, I’ve found this to be a worthwhile filter - just be aware of the lens flare artifact issue.

Was buying B+W until they went woke on their packaging and started shipping glass in cloth bags. These items are fragile and need a hard case for storage and bag transport. The NiSi is similarly optically flawless, and the threads are well defined and cut. Thin, however female side threads are deep enough that lens caps fit securely and don't fall out. Will be NiSi forward.

The filter work perfectly with my lens and able to produce a clear image.
