K&F CONCEPT 43mm UV Filter Ultraviolet Lens Protection with Cleaning Cloth | Multi-Coated Japan Optical Glass, Reduce Glare, No Vignetting, Easy to Clean, Nano-K Series FV301

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.

A very well made, Japanese Nano, K&F Concept 52mm UV Lens Filter. It threads onto the end of the 52mm RF lens. It is easy to fit onto the end of a new lens. The UV Filter comes with cleaning swabs to remove any dust and debris on lens and to clean the UV Filter. This keeps the gap between to be clean and clear. To adjust the UV polarisation, just twist it: = or \\ or // or ||. The filter is compatible with the Canon RF 52mm lens (the Nifty Fifty - for RF Cameras). Always add a protective UV lens when buy new glass. It is easier and cheaper to replace a UV filter than it is to have to buy a new lens. It protects the lens from UV, polarisation, bumps, walking into things, turning into things, dust, debris, rain, etc. It is very versatile in how it protect the end and is still able to connect the light hoods and rain hoods, flash, etc. I always use a K&F Concept filter on all my glass.

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.

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.

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

I have bought it for my Canon RF 28-70 F2. I thought I would need to spend tons of money for a filter which will keep secure and dust away from the lens. I was wrong: good price and good quality. I recommend it.

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

Decent quality and no detriment to image quality.

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.

Got it for my EF-S 55–250mm f/4–5.6 IS. Worth It. Protection: I shoot outside a lot- car shows, dirt, pollen, flying bugs with attitude, and this thing’s been a great first line of defense. I'd rather clean or replace a filter than risk scratching actual glass. Bonus: no anxiety wiping it with a t-shirt if I have to. Optical Clarity: No weird color cast, no ghosting, and it hasn’t affected sharpness at all—even at 250mm. I was worried it might dull the image, but nope. Photos still come out crisp and contrasty. (note I have to stop this lens down to like f8 anyway as its pretty soft at 250) Build Quality: It’s super slim, threads on smoothly, and doesn’t feel like the bargain bin trash you sometimes get with cheap filters. Doesn’t get stuck, doesn’t rattle, and doesn’t look like a toy. ⚠️ Important Note: (I used an EMOJI, so you better read this!!!) CLEAN YOUR LENS WELL BEFORE PUTTING THIS ON. It threads on fine, but trust me, you don’t want to keep taking it off and on. Put it on once and leave it. Any dust, fingerprint, or oil on the front element WILL show up in your shots like a nasty watermark you didn’t ask for. Treat it like applying a screen protector, clean, then cover and LEAVE IT ON. Bottom Line: If you’ve got the 55–250mm or any 58mm filter size lens, grab this. Cheap peace of mind, no image degradation, and it saves you from the heartbreak of scratched glass or sneeze damage mid-shoot.

Decent price for a good filter. Doesn’t seem to have any colour cast or flaws. Easy on/off. No brainer to protect your expensive lens.
