Used to protect a Kamlan lens. I don't notice any change in the image with this filter. It was pretty difficult to put the original lens cap back on the lens without removing the lens hood and the UV filter cap is super easy to put back on! And thanks K&F for adding a wrist strap to the hood!

I've become a huge fan of K&F Concept. It's hard not to consider the cost of this line of filters. This is the first filter from this line I've gotten, all the others have been either the Nano or top-line series. The filter is almost disappointingly light, especially in the 52mm size I got. It has very deep grooves that really make it easier to grip — and they don't add to the overall diameter, so if you have a slide-on cap or hood, they won't get in the way. It's also very thin, which is a good thing — but is also my only complaint about the filter — the internal thread (on the front of the filter) is too shallow to accommodate the OEM lens hood designed for the Nokton lens I use it with. It kind of holds it, but it does wobble and play a bit, so I'm baffled by that. I tested it with the ~10 year old German "pro" level MRC filter that's been on the lens since I got it, and it's visibly a better filter in terms of overall contrast. (K&F's elevation filters are even better in this regard.) And for that cheap price, you get a lens cap and sealed cleaning cloth. The lens cap I bought separately was also the first K&F product I used that I thought had a flawed design, and this smaller one is too — the recesses for your fingertips do have plenty of depth on the cap, but the surfaces you squeeze to use the cap are completely smooth, and I have trouble using it. I was able to fix that by gluing a very small (~0.02 x 0.06) strip of plastic along the side edges of the pinch points, which makes these work really well. So — even at 4 stars (a high rating from me), there are things I don't like about this filter kit. But I don't think the shallow threads will be an issue for most people, and getting a really good filter for so little is worth a star to me.

I now have this amazing filter attached to my Olympus 60mm macro lens. The lens has no lens hood, a bad front cap and obviously no filter. This is now on board, along with a tidy front cap and third-party lens hood. 46mm is a little small and fiddly, but this one has a really good knurled ring that feels good in the hand. The thread is also very smooth and positive. The color balance is imperceptibly different, so it doesn't bother when shooting in well-lit close-ups. I love the improvement on this brilliant lens. ricky

Great filter and lens cap. I'm thrilled

Easy to use, easy to install, compatible with lens cap and lens hood. Fog filters are used to add cinematic flair to your photos or videos. Diffusion filters around your lights or objects like a misty "dreamy" halo. I definitely recommend adding this filter to your collection!

I am very satisfied with the optical quality of this filter. Especially in comparison (e.g. with Cokin) stell

I've owned high quality Canon DSLRs for a long time and they're great. But over the years, I've struggled with the combination of lens hood and lens cap. I must have spent hours removing the lens hood, which is almost four inches long on some lenses, to get to the loosening, squeezing things on the outer edge of my old lens caps.

The last lens I bought had one of those center squeeze types and I realized I should have had that type on all my lenses a long time ago.

These caps from K&F Concept are a smart move. They're relatively easy to use even with the lens hood attached, but the depth they offer for your fingertips is just enough. When I put them on, I feel like there is a risk of them falling off my fingertips. This is a bit scary because you don't want them making contact with the glass. You need confidence in this regard, as you cannot see what is happening in the dark area inside the lower areas of the lens hood.

You have an unexpected advantage. Being plain black with no logo or name on them, they remove the word Canon from the front of your camera for all would-be thieves to see. It might make your camera a little more secure.

However, they make up about a third of the price of most lens caps, even by market cap. So they offer good value for money if you are on a budget. I will use these lens caps until I find ones with a slightly wider contact area with my fingertips.

Magnetic Filter Attachment, quick and easy to attach or remove from the camera lens.
THe 1/4 Black Mist filter is fantastic and definitely one of my favorites. The Filter comes with 3 items

1) The Filter Ring that threads on to the lens end
2) The Magnetic filter
3) Magnetic Filter Lens Cap.

Common Question(s):
Can you use the canon lens cap with the Magnetic ring installed (YES)
Can you use the Canon lens cap with the magnetic Filter in place (YES)
Can you use the Lens Cap with the magnetic base without the filter magnetically attached (YES)

Overall, really good quality lens and it is a breeze to install. The Magnetism is strong and the lens cap does not fall off nor does the filter. It has just the right amount of magnetism to keep everything in place.
Very Good Lens and Concept for mounting it to the camera.
