This set of lens cap and filters came with a good carrying/storage pouch and three cleaning cloth.

Since replacement lens cap from the lens makers are always very expensive, I have always replaced and store the original lens cap with a generic one like the one in this set. This lens cap also came with an anti-lost leach which consists of a rubber band with a string attached. At the other hand, of the string is a small plastic piece with adhesive backing to stick on the top surface of the lens cap. With the rubber band attached onto the lens, the idea is the cap will be attached to the lens all the time. The problem is the top surface of the cap is not smooth but with patterns that makes very poor surfer to stick something on it and as result, it keeps falling off. The other issue is with the cap daggling under the lens while taking picture is also distracting. At the end I just give up with the leash and use the cap alone.

The UV filter decently made with metal ring and fairly low profile. The gear pattern on the ring also makes it easy to hold when attaching and removing it from the lens. The filter produces no visible distortion. It is a very inexpensive way to protect expensive lens from external elements and damages.

The CPC filter is a litter thicker than the UV filter, but that is expected. It has the similar gear pattern on the metal ring like the UV filter that makes it easier to hold on when attaching and removing it from the lens. The CPC turning ring has a bit of drag, while I prefer a smoother turning, some may prefer it. Its a matter of taste.

Overall, good set of filters and cap with good value.

While I wouldn't call myself professional, I have done quite a few paid shoots over the years. However, I am mostly a hobbiest photog of about 8 years.

I recently added a Canon 70-200 to the mix that was rather expensive, even if it was secondhand, because I wanted that super wide aperture. I took it for a spin recently, and I stressed the entire time about not having any protection on it.

This filter fit the bill. While it is not high end cost wise, it gets the job done. I haven't notice any distortion or color cast in post, so it is doing exactly what I intended it for: protection of this new, pricey glass. I love how sleek/slim it is; it doesn't add any bulk to an already-bulky beast of a lens.

This kit comes with so many extras! The microfiber cloths are quality. It's a win-win all around!

I originally bought this set for the lens cap--mine was lost somewhere at a street fair. I am very pleased with the lens cap. It is one of those where the connector mechanism is controlled by the center of the lens cap rather than the edge. It fits perfectly and I love it. The bonus was all the stuff that came with it! It came with UV and CPL filters. I don't need them right now but it is good to have backups. The same is true with the little string that attaches the cap to your lens so you don't lose it. The three lens cleaning cloths are great, although I cannot testify to how they work as I have not had the occasion to us them. The filter case is also very nice and would hold three filters separately. All in all this is a very nice set. I highly recommend it.

I got this bundle for the CPL and was pleasantly surprised by the quality of the pouch as well as the filters. I don't ever use UV filters, but even so, the pouch with the CPL and lens cap is worth it.

CPL's are a great tool to get deep blue skies and mitigate reflective surfaces. I tested this against another CPL I have made by Tiffen, and it performed pretty much identical. In the pictures you can also see how it compares when rotated to a neutral position vs no filter at all. I also attempted a mock CPL edit by lowering the luminance levels and boosting the saturation .

Although you can't get rid of reflections in post, you can get decent recents by darkening skies. However, I believe if you don't already own one, having a CPL is an essential piece of kit. Definitely worth the investment.

You can't beat these K&F Concept filter kits... While you don't really need a UV filter on a digital camera they make great lens protectors without sacrificing any image quality in most all shooting situations. I usually keep one on each of my lenses. I also like to keep my original lens covers tucked away and use a 3rd party lens cover so I won't ever lose the one that came with the camera lens. The CPL filter is stackable and great to use for shooting reflective surfaces like glass or water. This case is nice as well. You won't be sorry buying these filter kits.

I was kind of surprised at how nice this filter kit is considering the price. The kit includes a UV filter mainly for lens protection, a good circular polarizer, and a lens cap with a "cap keeper", which I'll never use. And it all comes in a very nice folding filter holder.

The Japanese made optical glass seems great with lots of coatings. I appreciate the CNC textured frame around the filters, making getting a grip much better. Sometimes filters get stuck and it's nice to see some way to actually get a good grip without using filter wrenches. The filters themselves are quite thin, helping prevent any vignetting with wide angle lenses.

The three included lens cleaning cloths are also a nice bonus.

Got this so I didn’t have to use step down filters for one of my long lenses. It seems to be well enough made and similar to the Nano X series of their filter line. For the price I think it’s good, but it does have some differences compared to my way more expensive Hoya polarizer.

PRO’s
-comes with a nice kit and carrying case. Good for putting other filters in.
-lens cap is great and replaced one of my older ones that broke recently.
-optically seems pretty good especially for the price.
-mechanically equivalent to the Nano X version of the filter I also have. Nearly identical build quality.

CON’s:
-compared to my Hoya, it does have a slightly more green cast to it. However, considering the Hoya is nearly 3x more expensive I’m not sure it’s quite worth the price difference unless you’re absolutely nitpicking color tones. Besides which, if you use Lightroom or something you can easily make the adjustment, and if you’re that picky about color out of the camera then you should only be looking at professional level glass anyway.
-the filter is slim so getting it off can be a lot trickier than my Hoya and B+W filters for some reason. I don’t know if it’s the coating on the threads or what but they are definitely sticky.
-not sure if it’s a con yet but just something to note: the outer coating on this has a purple tint as opposed to the Nano X version which has a green tint. Probably just has to do with the amount/quality of the multi coatings between the filters.

Overall it seems to do the job. I will update after some field tests if something stands out as wrong.

It is hard to believe I can get all these for the price of what I usually pay for one filter, the CPL works and the UV filter ring feel decent with nice coating. Plan to use this pouch to hold all my different size CPL.

100% recomendable

when I removed the UV filter from the packaging I thought that it was broken or missing the lens itself, I could only see the frame It was only after I touched the glass that I realized that it was just the clearest piece of glass I've ever not seen! very impressive
