To smooth out water in waterfalls or creeks, you need 9 or 10 stops of ND. The VND filters that go up to 400 are not enough.

It works, looks good. Good price

Works for daytime long exposures.

Makes for effortless long exposures. Pics are beautiful.

It turns out it is 365 ND NOT fully 1000 ND. Off by a stop and ⅓. At this level, density is hard to hold but it is neutral in color.

Impressed with the photo quality using this filter... I've got a very critical eye when it comes to color cast using ND filters, and there is NONE. The fit and finish of the filter is also very good... I've had color cast with more expensive (different brand) filters.... I give this 2 thumbs up and I'm going to stick with K&F Concept from here on out... GREAT BANG FOR THE BUCK... can't imagine why you'd spend more... ZERO COLORCAST IS ZERO COLOR CAST, whether you spend $30 or $130.... Buy this one! And spend your savings on other equipment!!

I took these filters to replace others I already had (always K&F concept always purchased here on Amazon) to have something practical, comfortable and light to carry around that fit my new philosophy for the outdoors and family needs (practicality and lightness). What I found was a wonderful surprise. These filters and the case with which they come are not only practical but are also well made, have good optical performance and have no chromatic aberrations. For me they represent a real REVOLUTION and now I'll explain why ...

Delighted with my 55mm magnetic filter kit. It is made up of 4 components, an adapter, a UV filter, a polarizing filter and an ND1000 filter. Both the polarizer and the UV have a thread, so they can be screwed onto the front of the lens, but they also have a magnetized part, so the rest of the filters can be placed magnetically on them.

The combinations to use CPL and ND1000 can be:
-Adapter+CPL, Adapter+ND1000 or Adapter + CPL + ND1000
-UV Filter + CPL, UV Filter + ND1000, UV Filter + CPL + ND1000

They come in a padded cover with an inverted zipper to prevent some water from getting inside in case of rain. It can be clipped on your belt or anywhere else for convenient wearing or carrying.

I have several types of filters, threaded, square and these. Without a doubt, the magnetic ones are my favorite filters, I am super happy with them because they are very comfortable to use, especially for that reason, because of the ease of use. It is very easy to put on and take off any of the filters. You leave the UV or the adapter and it is instant to place or remove any of the others. I always have the UV, which also has a thread on the outside to be able to put the lid on, the thread is fine, but the lid remains fixed and does not fall off. In this way, I always have the camera ready to put any of the other filters quickly and easily.

In terms of image quality I have little complaint, I have not appreciated any loss of sharpness or any color cast. I have been able to use both the UV+CPL+ND1000 up to 12mm on my APSC camera without vignetting.

The filter I use the most is the ND1000 and it is very easy to use. Put the parameters you consider for the photo and focus, change the camera to manual focus so that the focus remains fixed, place the ND1000. Now you will see everything dark and you will have to change the time. What time do I use? Very simple, take the time you have set and multiply it by 1000. A 1/125 photo without a filter should be taken at approximately 8 seconds to obtain a similar exposure.

If what you are looking for are good quality filters that do not negatively affect your image and that are very comfortable to transport and use, I would definitely buy magnetic ones. Carrying the squares is sometimes a nuisance and the threaded ones are much more uncomfortable for me, in addition to the risk of them falling, I am a bit of a hand and it has already happened to me several times with the threaded ones. With these at the moment no problem and very happy.

I leave you a video and some photos that I hope will help you!

I purchased this K&F Concept 67mm Magnetic Lens Filter Kit
for my Tamron 28-75 f2.8. These filters work great and fit on my new camera.quality looks good.
It was a great choice!.... It allows me to capture long exposure water shots on bright, sunny days. It's not a variable and it's too dark for those dark dreary, overcast days. You'll want a different filter for that. The filter is well made and easy to thread onto my lenses. It also comes with a nice case to store and carry. The images come out clear and sharp with no vignetting, like you might get with some filters. Great value, definitely worth the money. I tried to add more than one photo for examples, but couldn't. I'll try to edit and add more later.
I am happy with this purchase.

►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.

Now, the advantage?
You avoid moving your camera is you want to change the filter!!! This is the most important feature I would say!!
I keep my camera in one spot and 100% doesnt have to move AT ALL!! So with this magnetic system i just remove one filter and add another, easy as that. I dont have to screw anything!!!

►What you get? A nice pouch, a filter ring(the magnetic one), 1 uv filter, 1 cpl and one ND1000. You already know what they do because you are all photographers so its easy.

Build quality? Good, clean design, slim filters, nice pouch(has a ring so you can attach it to the bag, tripod and so on.

►VERY IMPORTANT!!
You cannot attach all 3 filters at the same time!!
ONLY one by one so dont try to attach more because they might fall and you damage them.

How strong is the magnet?
Once attached to the lens even if you run with the camera in your hand you will not lose the filter so dont worry.

►Easy to remove? I would recommend to use both hands to make sure you remove the filters properly.
The most interesting filter for my type of work is the ND1000, makes a massive difference. I dont have to explain things like filming at f2.8 when it is bright outside + shutter at 60 for 30fps because you already know what I am talking about.

Make sure you choose the right filter size, check and double check your lens size.

►Overall experience?
Impressive techology!!
