The K&F Concept filter arrives safely packaged. A dust cloth and a storage bag are included. The filter's workmanship is truly first-class. High-quality materials, great handling, a precise fit, and not too heavy on the lens or in the hand. The filter is easily attached to the lens using a twist-lock mechanism. The filter creates wonderful images that require no further editing. The price may be a bit off-putting at first, but in my opinion, you're getting one of the best filters on the market. Professionals MUST buy it, and amateur photographers CAN buy it without hesitation.

use this filter to protect my expensive 70-200 mm telephoto zoom lens. The filter appears to be of very high quality and does not affect the image. This provides optimal protection for the front element of the lens. A particularly good option for wildlife photography. It also comes with a luxurious little bag for the filter, as well as a cleaning cloth. The packaging is a great idea. You can make a picture frame out of it. I will be using this UV filter permanently on my lens and not removing it occasionally. This has the added advantage of making it easier to remove and attach the lens cap. The filter itself has a thread, so you can combine multiple filters.

use UV filters on all my lenses, primarily to protect the front glass, rather than for the actual effect. I usually use filters in the price range of around €30. This one costs five times that, and just unpacking it creates a wow factor. It comes in a mega package worthy of a flagship. Incredible packaging, including a felt storage bag with a microfiber cloth in a sealed tear-off bag. It really rattles and rattles, and without even having installed the product, you know you're probably holding something very high-end. As expected, the filter is top-quality and screws on easily. Do I notice any difference from my previous filters? Admittedly, no, but that may be subjective. Do I now replace all my other UV filters? Admittedly, no, at least not when it comes to UV filters, but K&F definitely has my attention here, so I will definitely take a look at the other filters from the Pro series (ND, CPL).

water resistant coating save my day

I'm comparing this item KF's regular Nano filter. At the same settings on my Panasonic 85mm f/1.8, I can see more detail coming out of my lens on this Pro filter versus the regular Nano Filter.Since I love the sharpness of the 85mm, I'd much rather use the sharper filter. It's probably not a big deal to those who aren't pixel peeping but I can definitely see a difference in the hairs and I really like this filter.

Love this camera lens and the case it came in! Very high resolution picture shots taken with this with unbelievable clarity! Very durable and made with good quality. Love adding this to my photo bag for must have shots!

Ok, so the filter itself is a UV filter and if it is doing its job, it protects your lens from damage, dirt, sand, etc without impacting image quality. K&F is a good brand and this filter does its job.The filter screwed on nicely without any of the squeaky sounds some filters make. I did not notice any impact on my images.The filter is thinner than some of my other filters, but it does have knurling in the edges to assist in twisting it on and off.But enough about the filter...The case is amazing. While some filters come in a hard plastic case filled with form-fitting foam, this filter comes with a leather (albeit maybe fake leather) and canvas semi-rigid case. The inside is lined with a micro suede type material and has a pull string so that you can get the filter out of the case without touching the glass. This pull string raises the filter up out of the pocket of the case much like some wallets that have interior pull strings to push out credit cards.Overall, I like the filter and am impressed with the amount of energy invested in the case. These seems like a quality product to me

There are people that claims that when you use an UV filter on your lens, the resulting picture quality is degraded. Maybe my eyes are not that sharp but I cannot tell the difference. This one can be used to protect your lens from dust and the accidental touch with your fingertips. You can clean with included cloth or buy some of these wipes for lenses. Better destroy or damage this one and not your $2,500 lens.

UV filters are mostly used just to protect the front of your lens. One of the biggest arguments against them, however, is that by using one you are putting a lower quality piece of glass in front of your expensive glass. This can lead to negative impacts in your picture quality such as loss in sharpness, extra glare, loss in contrast, etc. So with that being said, the best thing a UV filter can do is be as unnoticeable as possible and that is exactly what this K&F filter is. I use this filter on my Tampon 70-200 2.8 G2 and I can confidently say I have not experienced any negative impacts on my pictures. I have experienced no glare, no vignetting, and no effects on the image quality. This does perform better than the cheaper UV filters I've bought from amazon in the past. If you have a pro-grade lens and want to protect the front element, I would recommend investing in this UV filter rather than one of the cheaper ones. I think that if you went the cheaper route, you'd either find yourself coming back to get this one or getting frustrated with using a UV filter in general.

This filter, if nothing else, helps keep my marriage on an even keel.Now I won't rehash the old UV vs non-UV filter debate, but personally I don't really feel I need a UV filter on my DSLR lenses, and if I were the only person using my cameras I wouldn't bother at all as I'm extremely careful with all of my equipment. My wife, on the other hand...Every time my wife takes out one of my cameras she treats it the same way she treats her sunglasses (lenses down on the dashboard of her car, jamming them in her pockets without a case or a second thought, smudges... just... everywhere. Oh, the humanity). When it comes to optical equipment she's history's greatest monster, a true menace to glass, but complaining about this to her will only ever end in a resentful argument.So the solution? A high quality UV filter that will protect my lenses without reducing image quality. I've tried cheap filters in the past that I've ended up removing every time I take a shot because there's noticeable degradation in the results, but as this is a high quality filter I can't see any different in the final product with or without the filter. All I see is a clean, scratch- and fingerprint-free lens coming back to me safe and sound, and that's worth its weight in gold.
