I own quite a few K&F Concept Products. They provide quality products without the hefty price tag we're used to see in the photography world.Let's talk about the filters individually first. All 3 filters are of top quality, at least on this price point/tier, as we're used to get from K&F Concept products:-The CPL Filter has no color shifting and performs as expected.-Same with the ND1000, although i don't use 10-stop filters that often (my most used filter is a VND Nano from K&F Concept) during my test it worked well, no cross present, even while using step-up rings.-The UV Filter has no color shifting and the main purpose these days of the UV filter is to protect the lens surface, BUT, It is where this VERY MINOR issue this kit has: The magnetic ring holder.The magnetic ring holder works great with the ND and the CPL, just not as good with the UV Filter, but it is not by ANY MEANS bad or i'd call it unsecure, at least not on the 82mm filter size version, your mileage may vary depending on the kit size you got as the magnetic surface may be different for your version, just the grip doesn't feel as tight as it does with the other two filters and there is a TINY bit of play, but not enough to warrant losing a star over it, i mean if you shake the camera at full strength you may drop it, but on regular usage i do not see it just falling off the ring holder.As the sum of all parts i'd say this was almost perfect. This kit complements my VND ND2-400 and includes everything i need to cover all my filters along my step-up rings. The UV filter thing doesn't make it lose a star, but maybe half, so i'd say 4.5 but since there's no option for that if i had to decided between 4 or 5 stars, i'll go with 5.

I really like the convenience of this magnetic filter system. You only need to thread on the base ring and magnets do the rest. Makes it less likely to damage the threads of your lens if you don't have to keep putting on and removing a filter on every time you need to use it. I am using this with a 24-105mm full-frame lens and the base ring works with the lens cap and the hood although you probably need to remove the hood to snap on the filter because otherwise your fingers get in the way.Each of the filters themselves are quite a bit heavier than the screw on K&F versions, probably because they need to make the filter ring out of a magnetic steel instead of aluminum. Whatever the reason, they feel a lot more premium than the regular K&F version.In terms of performance, its a bit of a mixed bag. I don't have tremendous experience using CPL and ND filters (this is my first set) so I don't know what's considered good performance at a given price range. Lets start with the ND: It seems to be close to if not a full 10-stops which is great; the previous K&F screw-on 10-stop ND which I returned clocked in at only around 8-stops in practice. The ND does have a noticeable color cast (see: photos of the sea right out of camera). Bringing the raw files into Lightroom, the ND image had 26 more points of magenta tint and was 1000K warmer than the no-filter image. This cast was reasonably easy to correct although the colors weren't exactly the same. Less correctible was the vignette at 24mm which needs to be cropped out. At least on my lens, a quick crop test indicated at I was loosing about 1 mm of focal length to the vignette. Note that since the filter is magnetic, there is a small amount of float between the filter and the lens so the vignette may not always be symmetric or consistent from one use to the next.Moving on, the CPL filter (photos looking out the window) has similar vignette to the ND filter at 24mm but appears to cut down quite a bit of reflections in my windows. Not much for me to point our here, it seems to do the job.The set does come with a UV filter but I do not intend to use it unless I am in a rainy/dusty environment where my lens needs a bit more protection so I haven't tested it out yet.For both the ND and the CPL filter, I did not detect any noticeable decrease in sharpness caused by using the filters. However due to the color cast with the ND filter, I suggest either shooting in RAW or setting your white balance before putting the filter on.For the price ($110) I think the performance of these filters is acceptable. I am a little disappointed with the vignette but I have heard of much more expensive filters having similar issues so I don't want to be too hard on this set. All in all, for someone like me who does this for fun, I think its a great system to learn the basics until I can justify the move to something more premium. If you're a professional and make money off your photos, then maybe look at something more upmarket like Freewell or invest the time creating a preset to fix the color cast.

I am absolutely satisfied with the overall performance of the package price is certainly here the magnet is strong enough and I could not notice any gaps as described in other recessions. The bag offers good protection and attaches well with the double Velcro and loop for a hook. buy a magnetic filter again at any time

I have to say that I never used filters before - this is my first try.I like ND filter. I do not see discolouration or sharpnes loss in images.I am a little disapointed with polarizing filter - it removes very little reflections and I wonder if it depends on filter quality how many reflections CPL filter is able to cancel out?I do not see a difference between with or without UV filter - I won't be using it.I wish they had a set for 92mm lenses.

I'm a photographer and I love adding accessories to my kit. One piece of the "kit" that has been elusive to me is functional and easy to use filters. I have a great set of variable ND filters, but the only thing I struggle with is aligning them exactly to screw them into the lens. K&F Concept, a surprising and budget-friendly accessory maker, has a really cool set of magnetic lens filters. The set comes with a waterproof carrying case, adapter ring, MCUV filter, CPL filter and ND1000 filter. The idea behind this set is to screw on an adapter, leave it on the lens, then switch the filters on and off as you need them. You don't waste time pulling trying to align the filters just right. I think it's a great filtration system. The filters are well made and of high quality.

As a photographer, I use filters, but it's not always easy to put on or take off depending on the situation. But with this system, it becomes so simple that it's almost instantaneous. The product is of very good construction quality and it comes with a 4-pocket pouch that is very well made and resistant against possible knocks. It can be attached to the belt with a Velcro. The kit is composed of two screw rings, one UV and one vacuum on which the CPL filter or the ND1000 can be fixed. I really wanted to go and test this new product. First with the CPL filter alone and then with the CPL filter + the ND1000 together. The results are just astounding. Here are the renderings with the CPL filter on the left and the CPL + ND 1000 on the right. With the filters it does there is no loss of sharpness, and color drift is almost nil. The CPL filter polarizes perfectly and the ND 1000 filter is very surprising in terms of its performance, it is very thin which limits vignetting, a plus. By using the two together, it is better to avoid ultra wide-angle focal lengths, but from 16mm, no worries, you can add them. In addition, they are compatible with my sun visor, I was able to put them on and take them off without having to take them off very easily because the magnetic force is perfectly dosed. Really very satisfied with this first outing, I hope others Intermediate magnetic filters with this system will be released soon to complete the offer. If there were magnetic lens caps, that would be great.

Quality is okay for the price. What is missing, however, is a magnetic lens cap from Canon that no longer fits. But I found a solution. Lens cap snap-on protective cover.

 Just when you thought....who would reinvent the wheel? K&F has def done it! I have the swarm of traditional filters and always screwed them on and off, carried them with me etc. All the standard ways we are all use to. This caught my eye when I saw "magnetic" and though.....eh, seems odd.But im always up for and easier life when it comes to those little things so i gave these a shot. And now, I find if i had to screw on my filters, it would drive me nuts. This is a MUCH MUCH better mousetrap to the filter game! I find myself swapping filters more often, and using these more than i usually would. The magnets are strong and the filters are what youd expect from them. So far i am LOVING these. They clip on easy, you screw on the magnet ring, and then the filters clip to it. Your lens cap goes on the filter, so if you dont want the filter, i tend to take it with the lens cap and put it to the side until i need it.If you use or swap filters a lot, do yourself a favor and get these! Im about to order a few more sets for my other lenses.

I had been wanting to try a magnetic filter system for a while so I'm glad I got my hands on these. All the magnets work well and it's easy to screw on the adapter onto your lens. I personally only really use the ND filter, but the other 2 filters could stack on no problem and without any degrading in image quality or color.I was able to look closely at high resolution RAW files of photos I took using the ND filter and they looked extremely clean. The little carrying case is a nice touch as well.One suggestion is maybe adding a 6 stop ND filter to the set. There were a couple times where the 10 stop was just a little too much light blocking for me.I would definitely recommend this to most photographers as a great and easy all around filter system

Beautiful object well designed, and the filters are of quality.
