Speaking of myths, what do UV filters do? Originally, UV filters and their cousins, Haze filters, were placed in front of the lens to mitigate the effects of UV light on panchromatic and color films because they are close to blue in the light spectrum. This is not a problem in digital photography. Some (here) say that a UV filter prevents UV damage to the lens or its coatings. Interesting, but I've never heard this claim before and couldn't find a knowledgeable photographer who did it via a web search. Some say that a UV filter can protect a lens from breaking if dropped. Most photographers/lens manufacturers agree that today's lenses are far more robust than a UV filter, which can very well be broken if the lens is dropped. Some say that a UV filter can cause flare or ghosting (especially in high-contrast scenes) in the final image. Most photographers report that when such an event happens, it is barely noticeable. UV filters serve a practical purpose in digital photography: they prevent scratches and foreign objects from coming into contact with the front part of the lens. The point is that dust, sand, saliva, sweat, rain, snow, salt spray, etc. are easier to clean off a filter than a lens, while protecting the lens from relentless, potentially abrasive cleaning programs. I got this filter to test for chromatic aberration, flare and ghosting - while using it as a lens protector. I haven't noticed any significant effects. If I want to be picky, very high contrast scenes (bright lights on a dimly lit street) can have a bit of ghosting. The filter is well made, robust and has no visible flaws in the glass or coatings. Without wishing to demean anyone, I suspect that the average photographer would not see any negative effects in their images due to this filter. I received the 72mm, which I fully recommend.

Some say you don't need this with digital photography, but I've always bought a UV filter to cover my entire lens. No more worries about fingerprints or dirt and dust getting on the lens. Great price and packaged very well, love the case it comes in.

I continue to be impressed by K&F Concept equipment. It's well-made, and the quality of the optical grade glass and the coatings are both really decent. I didn't notice any drop in sharpness.

UV filter can improve the look of some outdoor photos in bright sunshine, but to be honest I can't tell much of a difference. Like most people, I use UV filters to protect the front element of my lenses. When you are shooting in a place where the lens might get a hit, such as in the rain, at the beach (salt spray) or by the pool (splashes), at a party where people might be careless with drinks, or around children / Pets who might reach out and touch the lens, a UV filter is good protection. It's a lot easier to clean a filter than the element on an expensive lens! Of course, for this purpose you want a filter that doesn't degrade the quality of your images, as far as I can tell this one doesn't. I didn't notice any visible darkening or color shifts, in fact when I first opened the box for a second I thought there was no glass in the filter ring! Overall I think this gives your lenses some protection without sacrificing image quality. And of course, if you are in a place that is safe for your lens, you can easily remove the filter. While that's not a disadvantage, I wish K&F would standardize their filter housings. I have already received 3 different types and it would be nice if they had a stamp/sticker on the outside so you can quickly identify what type of filter is in the box! Luckily I have a label printer.

This filter doesn't affect the picture abilities of the Nikon P950 when on the camera. It helps balance the photo's and doesn't detract from the camera's abilities, like the 2000mm zoom.

Fits onto the lens well, with no problems. Came with a nice package and lens holder. You can use other lenses over it, because it's threaded on the outside also.

I would highly recommend this filter from K&F Concept. I was pointed to them as company from a photography magazine. I own one of their filters and now their carbon fiber tripod which is also a high-quality product at a superb price, in other words, a great value.

Thanks K&F Concept for a great product at a reasonable price!!! A+++++++++++

I've mainly switched to tempered glass for the extra protection since I don't use lens caps and I stack lenses in a small bag when on the go.

I didn't expect the quality to be this good. filter comes out of the box with a coating that feels quite slippery.

I just wish the letters on the filter to be of darker color instead of "cheap white" but performance wise, it's been amazing.

A UV filter may help the look of some outdoor photos in bright sun, but honestly I can't see much difference. I use UV filters like most people do, as a way to protect the front element of my lenses. If you're shooting someplace where the lens could get stuff on it, like in the rain, at the beach (salt spray), or the pool (splashes), at a party where people might be getting sloppy with drinks or around kids/pets who might reach out and touch the lens, a UV filter is good protection.

I haven't noticed any visible darkening or color shifts, in fact when I first opened the box for a second I thought there wasn't any glass in the filter ring! So overall I think this will offer some protection to your lenses without changing picture quality. And of course, if you're someplace that isn't hazardous to your lens you can easily take the filter off.

While it's not a downside, I do kind of wish K&F would standardize their filter cases. I have received 3 different kinds already, and it would be nice if they had a stamp/sticker on the outside so you can quickly tell which type of filter is in the box! Luckily, I have a label maker.

I really enjoyed adding an extra layer of protection to my lens from the elements. The protection did not affect my image quality or my autofocus. It provided a high quality image.

With modern DSLR cameras, there is a lot of debate as to whether there is any benefit to UV filters. I'm in the camp that says there are definite benefits. First, there are arguments that the UV filter can protect the sensor in your camera from long-term UV degradation. Second, a good quality filter provides a layer of protection for the front of your camera lens. I was shooting in a very windy location and a door caught the wind and banged the front of my lens before I could get a hold of it. I was lucky that the hit wasn't worse, but the lens got a small chip on the front plastic. This filter is metal, screws directly on, and will protect the front of the lens from such damage in the future. The lens could still be damaged in other ways, but it's a layer of protection from those unexpected bumps. In the future, if the lens gets bumped and the filter destroyed, I'll be grateful that the filter took the hit instead of the lens. The filter is much cheaper to replace!
