67mm HD MCUV Protection Filter 28 Multi-Coated Filter - Nano-Xcel series Toughened Glass

K&F makes fixed filters and this UV filter is no different. My 24-70 has been naked for a while and I decided it was time to get it a protective UV filter as I've added it back to my rotation of travel lenses so I ordered a matching 77mm Filter. The K&F filter surprised me when I first unpacked it. First, the case is fantastic. It's a smoky transparent hardshell plastic case secured with 4 tabs and a quick twist to lock and unlock. It's a large filter housing as the same housing fits 82mm filters but can also fit smaller filters down to 43mm. And the filters don't slip around. But how? Inside the case are two conical sections made of silicone, a small one with 2 ribs and a large one with 10. The large one has numbers next to each rib indicating the size it fits (43, 46, 49, 52, 55, 58, 62, 67, 72, 77, 82 ). The small one with 2 ribs is meant to hold the opposite end of the filter and stabilize it. As long as your filter is one of the sizes listed, it should fit this housing and be held securely in place by the silicone ridges. Now it holds my single layer filters with no problem, but it doesn't fit my variable ND filters or filters with rotating handles/extensions that protrude.

The filter itself is very well made. The aluminum housing has built in two sections with thick knurling, making the filter easy to grab during installation and removal. The filter itself does not noticeably affect my image quality on my 24-70 compared to no filter when viewing an image up to 2x in Lightroom, nor do I notice any significant color cast. For me, the K&F UV filter is well designed and easy to use.

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.

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.

If you are looking for quality protection for your lens, at this price point, K&F Concepts is hard to beat. The quality of the materials, fit and finish. And the overall clarity and protection of this product provides a fantastic way to keep a variety of things from getting to and damaging your more expensive lens.

It is a great comfort to me to have a guard that does its job so well that I don't even know it's there until it's successfully protected me.

Overall this product is very well made, it fits my lens perfectly and does a fantastic job at what it is supposed to do. If you need UV or more importantly damage protection then this is a great choice which I would highly recommend at this price point.

I have attached some pictures and videos to show the quality of the product. I hope you found this information helpful in making your decision.

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.
