77mm MCUV Lens Protection Filter 18 Multi-Coated Camera Lens UV Filter Ultra Slim with Cleaning Cloth (K-Series)

Seems to be high quality. I put this on my spotting scope as a lens protector. I see no image issues. Decent price, came shipped in a good protective case and included a cleaning cloth.

I'm thoroughly impressed with the K&F Concept MCUV Lens Protection Filters. The build quality is exceptional, with a sturdy metal frame and scratch-resistant coating. The filter is ultra-slim, making it perfect for use with a variety of lenses. The Multi-Coated Glass Provides excellent protection for your lens while minimizing reflections and flare The Ultra-Slim Design Fits perfectly on most lenses, reducing vignetting and improving overall image quality. Scratch-Resistant Coating actually works. Easily cleanable leaving a streak free CLEAR image! This filter performs flawlessly, with no noticeable impact on image quality. It's perfect for protecting your lens from dust, moisture, and scratches. I've used it with my vintage Canon FD lenses AND my LUMIX PRO lenses! They are INVISIBLE to your sensor!!! Considering the price point, this filter is an absolute steal. It's an affordable way to protect your valuable camera lens without compromising on image quality. I now use these on ALL my lenses!

Got it to put on Nikor 50mm lens. Fit perfectly. Great filter for the price and not bulky. I have owned filters from this brand and haven’t had any issues. Easy to attach and durable.

I purchased the 46m version of this UV filter for a Nikon Z series lens. I can confirm the glass is coated to reduce glare, and it does seem to work fairly well, especially compared to an uncoated filter I was using before. The build quality is good and there are extra rugged grips on the sides, which help if the filter gets stuck while being unscrewed. For the price this is a great value, and I'll probably get some additional sized for other lenses.

I think the K+F Concept Nano-K is a good value for casual shooters wanting protection from the elements, pets and fingers. Not much image degradation compared to B+W or Hoya HMC and (with microfiber cloth) sea spray and sand are easily wiped off. However, the knurled "non-slip" ribbing on the filter ring prevents some of my lens hoods from attaching to the camera. The HB-6 for the Nikon 24-70, for example. Not a huge deal but have never experienced this in 40 years of photography. And I want to relate an experience which does NOT affect the rating but is going to make me reconsider using K+F filters. Today, I dropped a lens onto concrete from chest height. It's been a couple decades but I've done this a number of times. Previously, every time the filter hits the ground first, the filter shatters and the ring deformed. B+W, Heliopan, Hoya, Tiffen behaved similarly. Today, the K+F filter (pictured) did not shatter nor become deformed and I believe it transmitted more force of impact to the lens than if it had shattered. The focus ring of the AF-D lens is so stiff it will no longer autofocus.

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.

I am using the 82mm MCUV lens filter on my 85mm f/1.2 lens and love it so far. I don't know if its me, but it seems to add a bit more contrast to my images which im actually fond of. I have yet to notice any degradation in image quality as that lens is crazy sharp. I also have the 77mm for my 35mm f/1.2 lens. The colors and detail look amazing and it protects my front elements from dust, dirt, scratches and light damage. Great as a protective element

Fits perfectly on my kit lens. Great quality. Easy to screw on and screw off.

Idealnie pasuje do obiektywu Canon 50 mm 1,2.

ممتاز

Really nice filter..Took some shots at night and day and no flaring at all.Seen zero degradation of image quality.

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.

Good quality
