58mm HD MCUV Protection Filter 28 Multi-Coated Filter - Nano-Xcel series Toughened Glass

Quality filters from K&F Concepts at an affordable price. The filter is slim and easily screws onto my lens. I experience no vignetting with this filter on my 18-45mm kit lens. The lens is clear and provides a layer of protection for my lens. The photos included show the photo taken with no filter attached (the one with the filter in the photo) and then the same shot after I installed the filter. No difference - exactly what I'm looking for. You can't go wrong with K&F concepts - high-end quality at a budget-friendly price.

Got caught in the rain with the filter at a football game for the first time. The rain wasn't predicted so I didn't have rain gear with me for my cameras. I was amazed at how the water beaded off the filter and I was able to shake it off most of the time. In terms of image quality, I couldn't tell any difference between this filter and a much more expensive black and white filter. I bought several.

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.

Definitely low profile, camera UV protection. I think there is a bit more contrast in photos too, which is welcome! Highly recommended!

A UV filter can improve the look of some outdoor photos in bright sunshine, but honestly 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.

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.

I put one of these on each of my lenses. This is the best quality filter I have ever bought - I am impressed with the clarity, the glass and the ease of screwing it in. Losing a star because the housing it comes in is TERRIBLE to reassemble and I actually ended up throwing it away and using a competitor filter housing.

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.

UV filters are often used to block extended UV rays on the front of a lens and as a longtime photographer I remember the days when a UV filter was a must to protect your lenses over the long term. ...or at least that was the theory.

Unfortunately, much of this belief persists to this day, and while the benefits of a UV filter that provides protection is still a hotly debated topic, UV filters offer a very good benefit...they keep dirt/grime/fingerprints back from the front Main element of a camera lens.

In wedding photography, it's not uncommon for a child/baby/drunk adult to reach out and try to touch your lens...in fact, attempts to do so can produce some of the most incredible shots if the timing is right.

However, the expense and difficulty of cleaning a good, high-end lens is often many times more difficult than simply cleaning a lens cover on the front...which is where UV filters usually come in...they do the job good job direct contact with the actual lens.

I've used many different types of filters over my decades of photography, and among these, UV filters are probably the ones that offer the widest range of quality.

This is the first K&F filter I've used and I've been using it on a Sigma ART lens for a week.

I'm happy to say that this filter is a nice mid to high end UV protector. Unlike so many cheaper UV filters, this one doesn't seem to introduce any easily noticeable color shift or image distortion with the image.

While I'm sure if I start pixeling and comparing this UV filter to a $200+ filter I could probably find a few glitches here and there. In fact, this filter is half the price of many of the other upper mid-range filters.

... and let's be honest. The primary goal of a UV filter is protection. A decent UV filter shouldn't noticeably alter your images. In this respect, this product does exactly what it is supposed to.

One thing the K&F excels at, however, is the case in which the filter is packaged.

The case is a hard cylindrical case that is easy to twist open. However, the nicer aspect of this filter is the fact that the housing has a silicone ring with grooves in it that holds the filter in place while it is in the housing. This is something many other manufacturers do NOT (including a large number of more high-end filter manufacturers).

While yes, this is the first real experience with a K&F filter, for me...after looking at the attention to detail they have done, I am now in the market for a few others of theirs :)

With modern DSLR cameras, there is a lot of debate as to whether UV filters are of any use. 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!
