It takes quite a bit to get excited about ND filters. These things are pretty critical for me to be able to draw my shutters - but it's been pretty much the same over and over again - just with less color cast or thinner frames. However, the magnetic ones are a major change to my slow shutter workflow. I tend to work in very narrow apertures and often times and that is with the UV and ND filters mounted. I can't recommend these enough — especially at the price.

The K&F Concept Magnetic 62mm Lens ND Filters Kit (5 Pack) GND8+ND8+ND64+ND1000 + Magnetic Filter Adapter Ring Filters Set with 28 Multi-Coated for Camera Lens:

This is an outstanding ND filter kit. The filters themselves are very good ND filters with no color shift. I have been using several K&F Concept filters lately and I find them to be among some of the best I’ve ever used. Overall very well engineered and constructed. This kit comes with 3 levels of neutral density and 1 graduated ND. The filters attach magnetically to a screw in ring, making swapping them out quick and easy. The magnetic ring is pre attached to one of the filters when the kit arrives, and you will use that one ring for all 4 filters. I really love the addition of the gradient ND as landscapes are one of my passions and this filter is ideal for bringing drama out of the sky. The kit also comes in a very nice filter wallet with several ways to attach it to your bag, belt, tripod etc. This is such a nice touch, and it really is a nice wallet, not just a cheap holder. I highly recommend this kit if you are looking for high quality ND filters. If you love to shoot very shallow and wide open, these are a must have. Solid color rendition, well designed and well made, high end filters.

It's better than some really cheap variable ND filters I got a few years ago.

It's a must have in your camera bag and at a fraction of the cost of other brands of variable ND filters.

What does a photographer do when they want to create a look for a photo session and that look requires multiple shooting angles.... but you only have one ND filter for one of your 82mm lenses?

... get another ND filter, of course.

Yes yes... I know, it was a cheesy way to start (but a very real problem we ran into a few months ago).

The fact is, I honestly don't know what's happened to K&F in the last few years, but they've gone from being "Oh.... Another filter manufacturer" to a "Wow... that's a fantastic result!!! Who makes this filter? '

This filter is NOT an exception to the above.

ND filters are often a double edged sword for photographers.... They work and they do what you want them to do.... sort of.

They tend to add color shift to your images, distortion if you have cheap glass, and they can often move your camera to the point where you have to manually adjust the shutter control... which leaves you taking photos after trial and error.

Also, when you use an ND filter, especially for very long exposures, you have to fight the light, so to speak. As the light of the day changes, so do your exposures.... and while you do a lot of trial and error, a 5 minute exposure at noon won't produce the same result at 5pm, so it's not like you can "set it and forget it" so to speak.

If you then add the word "variable" to the equation, things tend to get even weirder. When you adjust the ND, you often experience strange streaking, sudden fluctuations in exposure as you adjust the ring, AND that doesn't even take into account that so many ND filters have very loose adjustment rings that (I kid you not) can sometimes change their setting when a strong breeze blows.

This filter... IMPRESSIVE... I can honestly say that I have none of the above problems. There IS still a slight color shift, but it's consistent and doesn't change when you increase or decrease the ND level. Also, the levels are smooth and clear, and there doesn't seem to be any distortion... which is extremely shocking to me.

Also... there is NO rattle or looseness in the ring, which makes me happier than it should, to be quite honest.

The adjustment putter makes it easier to adjust without getting your fingers on the edges of the lens (makes it easier to adjust if you need to turn up or back depending on the light... this is especially helpful with video).

I really only have 3 complaints, and they are extremely minor.

1st) As with any filter, I would really like to see K&F either add a magnetic mount option or add a filter tool to make it easier to turn on and off. I know someone will say that the "putter" makes it easier, but I don't trust putting pressure on a free-floating multi-piece filter.

2nd) The case it comes in is different from the other Nano-X series cases. It's more of a leatherette type, whereas some of the others are more suede/denim style.

3rd) Threaded front element. I know some people will say, 'You NEVER stack filters!!! '. Yes, well, there are a large number of photographers who do.... if you don't want to, fine... but don't argue against any possible functionality.

It works amazingly well and does not interfere with the image I want to capture. So the "complaints" above are more of a wish list than anything else.

Definitely recommend.

I've tested the filter for a few days now and I have to say that I really like the option to adjust the ND level. With my old camera I had different filters, which of course is always a question of space if you just want to get going. Of course, the results are not comparable to much more expensive ND filters. But it's just practical to take nice pictures of bodies of water, or to put waterfalls in the right picture. What I have noticed negatively so far is that there was a reflection within the filter in direct sunlight, but this could be eliminated by a slightly different position of the camera. I will continue to test the filter. The durability must be observed to see if there are any problems with the rotating mechanism in the long run.

ND filters are expensive, what everyone who has dealt with it. Here you get a top product for good money.
