The set comes with six filters, all of which are useful and have their purpose.

The UV filter is primarily there to protect your lens from damage. It can also help with clarity in certain conditions. Well these are not to everyone's taste. I feel it's a useful addition and I have one installed most the time on mine.

The CPL filter helps reduce reflections and make colors more vibrant. I found the one included in this set to be reasonably effective.

The ND filters help reduce the amount of light entering the lens. This is essential when trying to control exposure.

All in all, I found this to be a decent set. It comes in a nice case. The magnets are strong on each lens and they can be stacked. The lens quality and clarity seems to be high. I would recommend these.

I like this ND filter a lot.

For me, this filter fulfills its purpose, but there are no better ones at this price, the x comes in the darkest setting, otherwise I see nothing

For me this filter serves its purpose and it is currently the best filter at this price

The main purpose is lens protection without compromising image quality. This UV filter meets these requirements.

Without being an expert on the quality of ND filters, I think they serve their purpose well, are well packaged and well protected (they are kept in a leather case) and come with a collection of rings to attach them to adapt to different lens sizes. Just remember that protection from the sun's vertical rays is imperfect and can have an impact. With a long exposure, when there is a lot of light, it is necessary to put your hand on the filter or put a flat surface on it.

I received this K&F Concept 58mm ND8 Lens Filter (3 f-stops), Fixed ND Filter with Double Sided HD 18 Layers Multilayer, Ultra Thin Optical Mount, Nano-X Series for Lensless Camera Lens in the Amazon wine program. Generate reviews on new products to be heard on Amazon. ND filters are designed to take long exposures and not overexpose photos or change colors. The filter also reduces the intensity of all wavelengths of light without changing the hue of the color rendering. It filters to reduce the amount of light entering the lens. This allows us to choose combinations of aperture, exposure time and sensor sensitivity that would otherwise produce overexposed images. There are difficult ND filters to control the amount of light entering the camera, that's three stops. This K&F Concept ND8 filter is well made and works well. I've only filmed it once so far, but it was very cool. These are a must have for any Phoargophère amateur or professional. I can highly recommend.

It serves its purpose perfectly. I used it to adjust my variable ND and be able to use the same filter for me 35mm and 85mm.
