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.

There are reviews that already comment on how well they work, so I will not repeat them, simply say that it is a pleasure to take them off and put them on and they are of great quality. The ease of moving the CPL with the ND mounted or not is great. Totally recommended. The only thing is that it would be appreciated to have ND filters with a different graduation, an 8 and a 64 for example, and also one for light pollution on request.

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.

Admittedly, the magnetic filter system is not entirely new and I can't say who copied it from whom, but I am already familiar with K&F through very good lens adapters and solid tripods. And since I have been flirting with magnetic round filters for a long time, but the prices for such a system seemed too steep, I was of course interested to see that K&F now also offers something like this. Whether the magnetic K&F round filters convinced me or the cheaper one Price here requires too many sacrifices, you can read that in my review...So far I have used screw-in filters from Rodenstock, B+W, Heliopan and Haida. So they're all brands where a filter costs what K&F wants for a complete set including a bag. I was therefore very skeptical about what to expect, also because K&F advertises Schott glass (hardened and therefore very robust) and 16-fold nano sealing. That sounds surprisingly good at first, but in practice it doesn't mean anything because in the end it's always about the optical performance, no matter how great the handling advantages are. Which is actually better, round filters or a 100mm filter system with plate filters, this question This is certainly a question that everyone who gets into the subject of filter photography will ask themselves. Until now, round filters always had to be screwed into the front thread of the lens, which can be very complicated depending on the situation and the lens. Even when combining several filters, each one had to be screwed onto the previous one individually, which in turn quickly leads to vignetting, at least whenever the filters have the same diameter as the lens. Therefore, a 100mm or even 150mm plate filter system has always been the first choice for professionals. Now the topic of round filters has been completely revolutionized by the introduction of magnetic filters. Changing filters has become so easy that the handling advantage of the plate filters no longer exists for me. On the contrary, with plate filters I always have to be extremely careful not to accidentally grab them (fingerprints) and unfortunately that happens very quickly when you take them out of your bag or put them in the holder. This is different here with a round filter with its metal frame. Of course, it can happen that you accidentally touch the glass, but the risk is significantly smaller and round filters are much more robust. Anyone who has ever dropped a plate filter will know what I mean

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.

The filters are great and can be changed quickly. Unfortunately, you cannot screw a graduated filter, even from K&F square and made of glass, onto the ring. The thread becomes larger. This means that you cannot connect the graduated filter with a polarizing filter. That is too bad

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.
