K&F Concept 37mm MC UV Protection Filter with 28 Multi-Layer Coatings HD/Hydrophobic/Scratch Resistant Ultra-Slim UV Filter for 37mm Camera Lens (Nano-X Series)

Perfect companion to my Fujifilm X100V and Hogue Lens Cover. The fact that it’s waterproof is a plus; this filter is an outstanding addition due to its WATERPROOF HIGH QUALITY UV FILTER QUALITIES. Happy to find it available at Amazon.com Arnold

Still, well-made and even comes with a cool case. But, c'mon. your cost to manufacture against your selling price?

Good value for the money. Would highly recommend

I purchased this for a Vortex Razor spotting scope to protect the front lens. I've done this for most of the spotting scopes I've owned as just another level of protection for the glass, as I do for all my camera lenses...it might be over much, but I'd rather have to replace this filter after days in salt air or other moisture. Using the filter forfeits the use of the rubber lens cover, but the Vortex comes with a neoprene cover so the rubber cover is a bit overkill. This was one of the least expensive filters for the size, and it fits a Vortex Razor scope with an 85mm objective.

I almost returned this when I found out my lens came with a free "$50" Sigma lens uv filter. The optics on it are wonderful, however I'm about to go to Niagara falls and I imagine I won't want to marry my lens cloth.I thought - why not just test them both under the sink before I send it back? So glad I did!Like magic, this K&H filter flows off and all the water dissapears. The free sigma filter? It soaks the water in! And it's hard to get off!If you got a free high quality uv filter and you're dry 24/7 - no need to upgrade. If you value versatility in any weather? Buy this now!

Some of the best i have used

I use it mainly to protect my lens against scratches, debris.It reduces the amount of ultraviolet light that passes into a camera.Without this filter u will notice discoloration.It effectively removes The appearance of blue hues bled in their photos.

An excellent UV filter that fits perfectly onto my Sony 24-105 mm camera lens.

Unexpensive, but I will pay more for better quality next time. I'm an experienced photographer and bought this for my 70-200mm lens. After 2 weeks, the lens of the filter separated from the ring and was loose inside between the filter ring and the front element of my 70-200mm. The worst part is that I couldn't unscrew the filter ring. I struggled to take it off fearing to cause damage to my lens, and finally I had to bend the ring to take it off (see picture) The filter is now destroyed and I'm really disapointed. I've used many many filters in over 15 years and I never experienced anything like this.

I'm old school: I always put a UV filter on my lenses to protect the front element. If you want to know how valuable that is, just look at how much less lenses that have "just a little scratch" on the glass sell for on FB marketplace or ebay - in fact, most people just wouldn't buy one.Bottom line, for the price it's a no brainer.As mainly a wildlife photographer, dust tends to be a problem; I way prefer wiping dust off a cheap(ish) UV filter than potentially scratching the coatings on my expensive lens.I have not noticed it on this lens, but most UV lenses tend to add the slightest, almost-insignificant, blue cast to any image. Since I would process any shot I consider decent and "worth it" in Lightroom anyway, part of my workflow would be to adjust tone - hence this is not a problem for me.Well worth it.

Build quality is okay; they seems solid enough, but have a rough surface finish.. They are very slim, not the slimmest I've ever seen but pretty close.On some of my lenses, these work well, but on some, they flare quite badly. I'm not an expert so I'm not sure why this is or whether better filters would have the same effect. I haven't noticed any other issues like blur or desaturation that are known to happen with poor filters.I haven't done any formal tests, but just eyeballing things these seem to be a middle ground between the really cheap filters and high end brand name filters. I can't justify them for the lenses I have, but if I had more expensive lenses I'd probably go for a Hoya or B+W.

This was a much more reasonably priced 95mm UV filter to fit a super zoom lens. The cheapest available elsewhere was around $200 so this was very attractive. I'm sure it's not the best quality, but for an amateur/hobbyist like myself it's perfectly fine. Also, for my purposes I want it to be there on the lens to protect it, so that if anything gets scratched it will be the easily replaceable filter and not the outer element of the lens itself. I will most likely remove the filter for most shots, so quality of the filter is not important.

My bad for trying to find quality products on Amazon in the first place. I assumed with the mention of "Japanese Glass" that the product was a solid, Japanese filter. Alas, it is made in China. I should have recognized it with all the bad English-isms including the fact that this will "protect my poduct". Would go to a camera store next time, for sure.
