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

Easy to use, perfect fit. Essential lens protection for your lens. I have a Canon SLR camera and I am always using UV filter to protect the lens. Recently, my camera was on tripod and the tripod tipped. The UV filter broke, the lens was fine. Perfect self-sacrifice for the filter to protect the lens.

Originally ordered these as a replacement sacrificial lense for my RNVG dual night vision goggles that utilize the PVS-14 style lenses. They screwed on perfectly and I didn't notice any additional blurriness. Cheap and effective. Could be worth stockpiling these if night vision training is your thing and you consistently bump your nods into things. Time will tell how durable it is but it feels like the glass and protects against direct lense scratches so it's durable enough for me.

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.

It’s a good filter especially for its price. Insert smoothly. Clear and free of stains and or scratches which is good.

K&F makes very good (at least) filters have several in use on various lenses like the results so far. Probably some the more expensive brands are a little better but not by much in my opinion. Not sure about durability and more extreme conditions but for every day use think they are a great value for the money

This is a great lens protector for my Canon RF 70-200mm F2.8. It fits like a good glove and allows for sharper images. It reacts great with flare causing a real nice effect. I would recommend this product to my family members and friends alike.

I used to spend an enormous amount on quality camera filters - usually purchasing European or higher-end Japanese versions. These ran from $50 to $100 each, and yes, it can add up real quick. Then one day I laughingly (but not laughing anymore) ordered a $10-$12 K&F filter. When it arrived, I was stunned to see a superbly designed and high quality optic with a super slim design. Ever since then I've been ordering various sized K&F filters and I couldn't be happier. I highly recommend these. From you moment you get one, you will be pleasantly surprised at the packaging, the design, and the performance - just what you've been looking for.

Ever since I bought my Minolta SRT 101 camera back in 1973 I was taught to always buy a UV Haze filter to protect the glass lenses. These do the job of protecting expensive glass lenses.

Slim, fits perfectly, easy to screw on and off, well made.

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.

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.

Excellent protection for your lens, for little money, highly recommended!
