K&F CONCEPT 67mm UV Filter Ultra Slim Japan Optics Multi Coated Ultraviolet Protection Lens Filter with Cleaning Cloth (Nano-K Series)

This is a decent uv filter it fits on the threads very smoothly with little effort, works well as a uv and protective shield of the camera lens. Easy to fit nice and compact to. It doesn’t distort the colour of photos and gives a slight vignette and feels well made and durable. I have found it’s giving more camera flares though that’s the only downside but I can deal with that in post editing. I’d buy again and it’s a great price too for a good quality filter.

UV filters are a great fit-and-forget way to protect expensive lenses from scratches. This one is well made, fairly priced, and even comes in some of the most stylish packaging I’ve seen in a long time. A thoughtful extra is the vacuum-packed microfibre cleaning cloth — a genuinely useful addition to any camera bag. Made in China using Japanese Asahi glass, it offers quality at a value price. The slim profile and solid barrel grip make it easy to handle, and it protects my Canon lens with no noticeable loss in image quality. Fit and finish are excellent.

Received one day earlier than expected, at the same time as my new camera lenses. They fit perfectly, the quality is great. Many thanks!

I am a keen photographer of many years and recently purchased a very expensive lens (for me at least). Before I had even unpacked the lens I ordered this UV filter. The reason simply because the filter protects the front, glass, element of a very expensive lens. The second reason for using a UV filter such as this is that it can cut down atmospheric haze and bring a little more clarity and improved colour to an image. The effects are not dramatic - you will need to use other filters for that or, increasing, manipulate the image in Photoshop or similar software. This filter from K & F Concept (a manufacturer I am not familiar with) is well made. The metal is strong and for many the thinness of the filter will be a definite plus as 'think' filters can cause vignetting (blackened corners) especially when using deep lens hoods. Only four stars because I have only just fitted it to my new lens and so do not know what long term use will be like.

Look, I’m going to be completely honest: I didn’t buy this 82mm K&F Nano-K filter because I was worried about atmospheric haze ruining my shots. I bought it because I am clumsy, I shoot outdoors a lot, and the thought of a stray branch or a gritty gust of wind scratching my front lens element gives me anxiety. This little ring of glass is essentially a bodyguard for my lens, and so far, it’s doing a stellar job! Here’s why it’s earned a permanent spot on my gear: Invisible Protection: The biggest fear with cheap UV filters is that they’ll turn your crisp images into a muddy, flared-out mess. Happy to report that this Nano-K glass is practically invisible. I’ve pixel-peeped my shots and I can’t see any loss of sharpness or weird colour casts. Contrast stays great, even when shooting towards the light. I have the more expensive X series and to be honest I can’t tell the difference. Smooth Operator: The aluminum frame is nice and slim (no ugly vignetting/dark corners on my wider shots) and the threads are pretty smooth. It screwed onto my 82mm Tamron lens perfectly without that horrible metal-grating-on-metal feeling you get with some ultra-budget filters. Cleaning is actually... easy? Usually, budget glass loves to smear grease around like a toddler with a crayon. Whatever coating K&F used on this Nano-K version actually works. Rain droplets bead up and roll right off, and dust wipes away with a quick blast of a blower and a microfibre cloth. Is it a £100 professional cinema filter? No. But for a highly affordable piece of glass that lets me not worry about scratches, damage or keeping my lens cap glued on every single second, it’s an absolute bargain. N.B. If I was using it on a £6000 lens I would probably splash out for the X series, but on a £900 one it’s more than adequate. Save yourself a future heartbreak and just buy one. Your lens will thank you!

These fit my Sony lenses really well - Decent price and seem good quality glass.

Cheap but good

Excellent quality filter at a decent price. Bought to fit in my kit lenses to add a degree of protection from daily grime and grandchildren’s sticky fingers. They don’t add any reflections to the images, don’t compromise the image quality. They are thin enough so that they don’t hugely increase the size of my pancake wide angle and zoom lens to any great degree. Build quality is good but not comparable with my B&W filters however these cost over five times the price. Highly recommended.

I’m using this filter on a Fujifilm GFX 100S and have been very impressed with it. The filter is extremely thin, well made, and fits perfectly without causing any vignetting. Image quality remains excellent even on a high-resolution medium format sensor. I have not noticed any loss of sharpness, contrast, or color accuracy. Reflections are well controlled and the filter stays easy to clean. For the price, the build quality is surprisingly good. It provides reliable lens protection while remaining virtually invisible in everyday use. Highly recommended if you are looking for an affordable, slim UV filter that does not compromise image quality

A very attractively priced & good quality lens protector filter available in many filter thread sizes , a very good choice for budget-minded photograpers, I recommend the seller K&F Concept and their filters.

Uso questo filtro sul Sigma 18-50mm f2.8 per Sony e funziona bene: si avvita facilmente, non rovina le foto e offre una buona protezione alla lente. Il vetro sembra solido, i riflessi sono contenuti e il panno in dotazione è utile anche se basico. Nel complesso un acquisto semplice ma valido.
