52mm MCUV+CPL+ND1000+Adapter Ring Magnetic 4 in 1 Lens Filter Kit Waterproof Scratch-Resistant Anti-Reflection with Filter Pouch

Everything arrived well packaged and as expected.
Great quality and the carry pouch is awesome.

Van molt bé. A veure si aviat oferiu filtres gnd magnetics.

►This is something that I never expected to see since I use DSLR and lenses.
Honestly now, it makes a massive difference.
I am not talking about the filters because you can find these any time, I am saying here about the system itself which I find to be absolutely brilliant!

How easy is now? Very very easy and I explain why.
I use filters for filming outside which sometimes can be challenging because of the light, the sun comes up from the clouds, manual settings, everyting over exposed which is very bad for video.

►My lens diameter is 67mm so I got those. You have to screw the ring and then based on what you want to get you just have to attach the filters.........you DONT have to screw them one by one which saves you a lot of time.

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.

The filter is mounted directly on the lens. You can always take it, it is not heavy and you will get great effects with it!
Practice & optical quality:

many voices will say, such inexpensive filters simply can not reach the quality of a brand filter and also I was until now someone who would have immediately affirmed this, so much I was convinced of my B&W, Rodenstock, Haida and Co. filters. But now the surprise, the K&F filters show no abnormalities. No unnatural color shifts, no clear loss of sharpness, hardly any flare and ghosting susceptibility, simply nothing where I would say at first glance that it would be a reason for exclusion. And I think this fact has opened my eyes. Either K&F has found a manufacturer here who also does this for the brand companies, or as I think, they have simply inserted a second layer in the factory and instead of the brand name, simply lasered K&F on the filters.

I have loved that they are magnetic, because it is much faster to change one for another or remove them without having to screw them.

I constantly wear the UV to protect the lens and when I want to subtract a couple of steps of light or there is water, I leave the CPL fixed.

They have good quality and a reasonable price.
I have tried the variables and there is no color ; much better these, and I forget about the vignetting.

The ND 1000 is very correct also for long exposure.

I miss that the magnetic metal cover does not come in the kit, in the end I bought a loose ND 64 filter, to be able to have it and I love the speed to have the camera ready.

This is a more than successful set that is worth every euro, not only for newcomers to the subject. Ambitious users will also find a good alternative to the filters of the established brands.
It really remains to hope that K&F brings more of these magnetic filters on the market, because I would like to have another ND8 and ND64.
Therefore, I can, with a clear conscience, give a very clear buy recommendation.

It seems like an easy system especially if you can get magnetic rings for same size filter on different lenses

The filters are well made so far, the filter glass is flawless and the magnetic ring is cleanly finished.
The optical performance of the filters is good fa there is nothing to complain about, the polarizing filter is essential for car photography and is therefore almost always mounted on my camera.

These work perfectly as do all KF products I have used in the past and I'm happy to patronise their reputation and recommend this set.
