don't believe in UV filters too much on digital cameras but as a lens protector, they have value. This kit comes with a spare lens cap which is a really nice, handy bonus. Also there is a lanyard type cable for a reason I have yet to figure out. The obligatory lens cloth is also vacuum packed for some reason. Optically, the filter is fine. I observed no noticable colour cast, fringing or vignetting with the lens, which is all I asked and the price is reasonable for the quality, so from my perspective, all is good. Recommendable.

Fits my Nikon 28-300mm thread perfectly, very thin profile, you can see the optical coating on the glass, and it doesn’t affect image quality. Came packaged with case, lens cap (which has good grip and is secure), a cord to thread thru the lens cap and attach to your camera body, plus a sealed microfibre cleaning cloth. A very good package and well worth the money for the peace of mind it affords your expensive glass.

K&F Concept very slimline polarising 77mm lens protective cover. I like these lens protective filters because they are very high Quality Steel with polarising glass in one of thinnest threaded and lightweight I could find. The ultra thin high quality glass not only protects your glass (lenses) but to also with a twist can change the polarising to obtain the best possible photos for the lighting conditions. The lens also has multiple special coating layers to intensify colours with reduced solar flaring glares in images. I highly recommend the K&F Concept lens covers as I have the K&F on all my RF and on all my older EF lenses. A clean camera lens (front), with a clean (dust, lint free) K&F attaches together should remain thus unless unscrew - remove the cover.

K&F have yet to put a foot wrong in my book and this is no exception. Optically clear and well machined, this makes a perfect everyday filter and lens protector with the added benefit of being supplied with a lens cap. UV filters are the foot soldiers of the filter world, unsung heroes that have saved many a lens from expensive repair, all lenses deserve one and you won't go far wrong ordering this.

tested this K&F Concept 52mm UV Filter Here's what I found... UV blocking ilters protect lenses from dirt and damage (and stop colour shifts if you still shoot film)- but they can also reduce image quality - so I test all new filters and reject some. How did I test it? [1] Colour shift - I used a set white balance and looked for colour shifts with and without the filter in place on a Nikon DSLR with a prime lens set to its highest quality setting (100asa and F8) both inside with artificial light and outside in sunlight. [2] vignetting - I looked at the edge of the image for any additional shadows with and without the filter [3] flare and contrast- I photographed lightbulbs and the sun between tree branches with and without the filter [4] distortion - I photographed a newspaper page with and without the filter Pros✅ Viewed on a retina laptop screen I could see no differences except in contrast. This turned out to be the effect of NOT using the correct lens hood. Basically - and side lighting can catch glass and cause reflections. Internal reflections are what photographer call "veiling flare" and this kills contrast. As the filter makes the first glass surface of the lens much less recessed (and so more visible) it risks vcausing eiling flare. This happens with any lens - and the solution is to fit and use a lens hood whenever possible. Cons❌ none in "real world use". As with all filters, when I went to 800% image size there was a slight loss of resolution, but for my standard HDTV use or printing to 8x6inch size this was "invisible". The only difference I could see over the classic "Hoya" filters was that the filter ring is thinner and so better to use on a wide-angle lens. There is a cost to this however, as the light weight of this filter tells me it is made of aluminium and so is easier to bend than say the brass ring filters from B&W (which cost way, way more!) - so the moral of this is to leave the filter on the lens - or protect it in a rigid lens case if you take it off. And there you get a good snap closing filter box in the pack - along with some useful additional accessories. OVERALL - I like this - and would be happy to get it again. Unless you are ready to pay the £50 plus for the brass-made B&W filters, these seem to be as good as any other but at a lower price. Delivery was quick - it came the next day which is great service.

The 'K&F Concept 67mm UV Filter Ultra Slim Japan Optics Multi Coated Ultraviolet Protection Lens Filter with Lens Cap' arrived in a branded box. The lens is in a plastic case for protection, it also serves to protect one side of the filter, whilst the opposite side is protected by the lens cap. The filter was an easy fit to my Nikon P900 and as it is slightly wider than some filters I found it easy to unscrew after use. I would however recommend carrying a suitable filter wrench just in case. It would be nice to see a cover for the side of the filter not protected by the lens cap a the lens filter with cap attached are stored in a cellophane envelope in the case, I suggest putting the filter/cap combination into the envelope with the lens cap the same side as the flap which keeps the adhesive as far away from the lens as possible. It would be nice to see a protective cover for the second side of the filter, maybe something push on.

This little set from K&F is actually really nice. Not only do you get a well made 55mm UV filter, you get a spare lens cap, a cleaning cloth and strap for attaching it. Everything comes in a clear case. I would have liked to have seen a separate case for the filter but as it will most likely be fitted to one of your lenses it isn't really needed. The filter is actually really good quality and easy to attach. The lens cap is the pinch type. Which means it can be used with a lens hood. Overall a cracking little set.

am a photography enthusiast and I often use the reflex not only for passion but also on construction sites for work. To protect the lenses of the best optics, I decided to test this very low reflectance UV lens, which allows you to protect the front glass of the lenses from dust and possible splashes, but also from light accidental impacts that could otherwise scratch the original lens. The filter I bought is 72mm and is perfect on my Tamron 17-50 2.8 that I use a lot. It arrives in a cardboard box inside which there is a semi-rigid box that in turn contains the filter and also a 72mm cap that is really well made and equipped with an orange wrist strap, also well made and convenient for having the cap always at hand. The kit is completed by a microfiber cloth for cleaning the lenses. The frame of the lens is made of very well painted aluminum. Excellent feeling of the material and perfect threading. The response on the photos is excellent: it does not alter the colors and does not create focusing problems, ensuring greater protection of the main lens of my optics. I consider it a good purchase to have greater protection on important optics, especially if used in "risky" contexts. Well-made product and at a price perfectly in line with the general quality of the product: in addition, with the purchase you have a spare cap, really excellent for preserving the original ones and being worry-free.

The filter is so thin, translucent, and reflection-free that I DIDN'T SEE IT, and I was pondering how to justify the absence of an impregnably shrink-wrapped product. It took me several minutes to realize that it was, screwed onto the cap, ha ha ha. I use it on my favorite lens from the 80s, the 20/40mm on the Pentax Auto 110, and it works excellently.

The filter comes in a storage box with a microfiber cloth, a cap, and a wrist strap. The build quality is good. The wrist strap is attached to the cap and attached to the lens. This makes it impossible to lose. The UV filter does its job well, which is mainly to protect the lens from dust and other possible projections. In the event of an impact, it will also sacrifice itself to save the lens. I mounted it on a Can*n EF-S 55-250mm, and it fits like a glove. Good quality, fair price... Nothing to complain about, this filter is highly recommended.
