This is a review of K&F Concept 62mm Black Diffusion 1/4 Effect & Variable ND2-ND32 ND Filter 2-in-1 for Camera Lens with 28 Multi-Layer Coatings (Nano-X Series)I bought this to use with my Sony ZV-1 on which I have a Newer LS-18 Wide Angle/Macro conversion lens 0.75x. I was disappointed, but not surprised that there was very apparent vignetting at the corners of the photos. This is due to the wide angle lens. You can crop the photos in post production to eliminate the vignetting. Not ideal but that's what you have to do.If you use this on a normal lens and aren't stacking additional filters, I'm quite sure you won't have an issue with vignetting.The 62mm variable ND, 1/4 diffusion filter is great. The filter allows you to shoot longer exposures at slower shutter speeds in bright light conditions allowing you to get awesome shots that would otherwise be impossible to get without the filter. It adjusts to give you between 1 to 5 stops reduction. And since it's also a 1/4 effect diffusion filter, it gives a somewhat soft diffusion effect to the photo and is great to use for portraits.This is very nice quality filter and priced less than other comparable filters.

Game changer!!! Never had used a polarized lens filter and my photos have become sooo much more vibrant! Definitely worth the $ spent!

 Stabilzation is getting best when gyroscope is on. Photos are clear clean and crisp.

Fits the lens well, no change in the quality of the photos after the filter was applied, so it works like it is supposed to.

Can't believe I got this for.99 cent!! It works perfectly and I love interacting with my Alexa!

Gosh I love this lens! It takes beautiful, crisp, and clear photos every time. I use this on my Canon M50 and it’s a game changer. I took photos of my son for his first birthday and after a little Lightroom touch up they look perfect. Would definitely recommend!

Pros:- I bought this kit because I need the various Neutral Density filters for an experimental project, and for my works, they work quite well.- I've also used the CPL (circular polarizing) filter during outdoor shoots a lot, and I've realized it did make my photos look more vibrant and lively (when I placed the camera correctly).- Overall, I am glad I have this kit, and they can come in quite handy during daytime shoots or in any bright environment, like photographing a room of people at a long exposure while the room is well lit. Having them has improved my outdoor photos, despite the fact that they are super cheap. I recommend this kit, especially when you start learning how to use them.- Luckily, all my lens have the diameter of 52mm, so I can use the entire 52mm kit for all my lenses without needing an adapter.Cons:- When two or more filters are stacked together, they will cast a vignettes on the photos when shooting at a wide angle. From my experiences, the vignettes appears at a focal length of 24 mm and wider (18mm, 16mm, and beyond). The wider the focal length, the more extreme the vignettes gets.- When I used the filters on my Nikon AF 50mm f1.8, probably because the front glass of the lens is too far away from the filter, when I point the camera towards the light (indoor lights, not sunlight), the filter casts a ghost of the light fixtures onto the image. The "ghost" (reflection of light fixtures) is not present when I remove the filter from the lens.Just an FYI:- From my research, I've learned that in digital photography, the UV and FLD filters don't have much function, because their intended functions have been built into our modern DSLR's. However, it is still nice to have them. For instance, the FLD filter can give a very creative colour cast to the images.

Have had my previous ones for.10 years so was afraid to.purchase. these are better than the first
