The K&F Concept Nano Series magnetic filter kit is really extremely practical. The kit that contains the filters has a compact size, which allows us to carry it in our backpack, sacrificing very little space. The weight is extremely light, which is really useful for those who do long hikes where the weight of the equipment, after several hours, begins to be felt. Installing and removing filters is nothing short of lightning; in seconds you can easily mount the three filters and in as many seconds they can be removed. The grip of the magnets is really good and therefore there is no fear of ending up with filters falling off during the shooting or transport phase. WHO IS RECOMMENDED TO In conclusion, I highly recommend this value for money filter kit to: - anyone looking for a first filter kit to begin the creative experience; - those looking for an excellent relationship between quality, size and weight; - those looking for maximum practicality during filming and composition.

This is a premium quality glass at a reasonable price. The glass is flawless, the handles glare very well, and do not reduce the image quality at all.

There's nothing to be said about the quality, they are excellent for the price that they are.

I already own a backpack and an adapter for my Fuji XT-3 from this brand and have not been disappointed once. The adapter fitted perfectly and so did these ND filters here. My buddy and I are getting a little into the image film area at the moment and are trying out a lot in that regard. So far, we always had the problem with the Fuji that the sky was totally overexposed and I had to adjust the aperture. This problem is now off the table.

In a nutshell about the product itself: the supplied bag is great and by no means just a cheap prop, but a high-quality and sensible storage option for the filters. The filters themselves are of very high quality, fit my Fujinon XF 18-55 very precisely and do exactly what they are supposed to do without any compromises.

That pictures say more than 1000 words, even if it may sound trite, I've attached a small sequence from our last shoot, where you can finally see the sky. In this case only the ND8. A lot more should be possible with the ND64, even on very bright days. The price-performance ratio is clearly great here. My recommendation!

I bought these filters for my Nikon 49mm, and the result is really excellent. First of all, I found the packaging really well done, quality product. As for the filters, the system that holds them together is very reliable, protects the glass well and allows good portability in our photo travels. Personally, I found the lens really excellent as the quality and the final result. I recommend it to everyone from beginners to professionals because the performance is really great.

This magnetic lens filter kit is great for quick access to helpful filters. Simply screw on the magnetic ring to the lens and the filters will stick to the ring.

The MCUV was clear and clean, the polarizer proved useful for reflections when shooting on location, and the ND filter was great on bright days to help keep exposure in check. Be aware that the ND filter is quite intense, which is great for sunny days but sometimes too dark for overcast or evening shoots on certain settings.

You can easily clip the bag to a camera bag or belt when shooting light.

K&F magnetic filters - CPL, UV, ND1000 - Excellent choice !
Packaging : 6,5 / 10
Nice case that keeps the filters together and protected. With velcro and ring to attach it to a belt or backpack.
I don't particularly like the plastic box, I would have preferred something ecological like for other brands, but it's not something important in use so it weighs less on the judgment of the packaging.

Handling: 9,5/10
Excellent workmanship, the filter is metal, threaded which fits well into every lens in my possession.
Great that they are magnetic. In some conditions, screwing on a filter is very difficult and time consuming as well as the risk of it slipping out of your hands. In the case of the K&F magnetic filters, you just have to leave the holder mounted. If necessary, simply move the filter closer to the lens and it will attach itself powerfully and precisely.
This feature is the main reason to buy these filters.

Optical quality: 8/10
ND filter: Excellent sharpness: there is no loss of quality in high contrast areas. As with most ND filters, the filter has a purple/magenta cast, nothing that can't be corrected in post-production (see photos - doesn't work on PC just to show the quality of the filters). Slight vignetting, but really slight, nothing major. Score : 8/10

Polarizer / CPL Filter: Very very sharp filter, no loss of quality when editing. It tends to slightly "warm up" the images, but again nothing that can't be corrected with a touch in post-production. Excellent reduction of reflections on water and leaves affected by bright light. I don't like the effect of the sky being too intensified towards the Blue color (which also happens with all the other CPL filters I've tested). Important note in this case, it does not produce any additional flare compared to a use without filters

UV filter: I never use UV filters because I find them useless except in case of danger for the lens (salt / water splashes / resins, sand). I must say however that this one has a good performance, it does not lose sharpness or worsen the flare compared to the lens without filter.

Quality/Price: 9/10
For the general quality of the filters in question the price is LOW.
Such a kit is suitable for both demanding amateurs and professionals because the weak points of these filters are few and in any case surmountable, while the strong points (speed of use and sharpness) are more important.

I really like the concept of this set of filters. I’m not the most coordinated person, and switching filters in the field requires some coordination, so I have just been using a single filter - and it shows in my photos. I really like that this set really requires very little coordination. I’ve been able to quickly and easily switch filters as the lighting changes.

The set comes in a nice padded fabric case with individual pockets and a Velcro strap to attach to a belt.

The set includes three magnetic filters and an adapter ring. The lightest filter is a UV filter that looks completely clear. Like the adapter ring, this filter is threaded. It is the only filter that is threaded, and is also the only filter that seems a bit loose when on the adapter. The other filters fit much better, but they fit just as well on the UV filter, so I’ve chosen to skip the adapter ring and just thread the UV filter to my lens and attach the other filters to this one. It obviously means an added layer of glass when setup this way though.

Anyway, I like this set and would recommend it.

They are very easy to use and the quality is fantastic - both build quality and image quality. I don't see any color from the CPL filter and ND filter. I think you'd really need to pixel peep to see any difference in sharpness, and even then I'm not sure there is. Being able to attach the filters to both the UV filter and the filter ring is really smart - I keep the UV on my 24-70 F4 and the filter thread ring on 16-35 F4 which makes the clip even more fast filters, no matter what lens I'm using. Since the ND is non-variable, there is no dark X and no vignetting at 16mm, unlike my set of square filters. The downsides I see so far:

I ordered this lens kit for my husband and it has been very helpful for his outdoor photoshoots. It is easy to install and the magnetic feature surprised us by how well it worked. The lens is water resistant and we haven’t had any scratches on it. This definitely helps out when you’re outdoors working. It also comes with its own case. Highly recommended.
