K&F Concept 95mm MCUV Lens Protection Filter 18 Multi-Coated Camera Lens UV Filter Ultra Slim with Cleaning Cloth (K-Series)

Got it for my EF-S 55–250mm f/4–5.6. 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.

This was the very first filter I bought for my kit EF-S 18-55mm lens, and it worked really well starting out. I wasn’t totally sure what an MCUV filter did at first, but I noticed it helped keep my images a bit sharper and definitely protected the lens from dust and accidental bumps. It stayed on my lens until I upgraded to a sharper, more versatile lens. Solid choice for beginners looking to protect their gear without breaking the bank.

Thin and light, sturdy and clear. Images look great through these filters--no discernable impact on color or clarity. Like many others, I am using these as protection for my lens elements, so I can keep the actual cap in a pocket and not have to fiddle with it while I'm out and about.The only downside I've had is with a friction-fitted cap on the Olympus 17mm f1.8. Even though this is the same outer diameter as the lens, the machined knotches, which makes turning the filter easy, also seem to snag on that lens cap. So now I have to get a more standard cap or fiddle more often with this lens. On some other lenses, I find this actually makes it easier to put the cap back on without looking. The slight protrusion helps.

doesn't fit Jupiter Lenses from Siriu, but looks like nice filter and price is good.

K&F offers excellent products at reasonable prices. I highly recommend.

This simply does the job. Goes on without any problem and the price is right.

It met all me needs.

estos filtros son muy fiable para la protección del lente de mi cámara
