I needed to protect the lens on my FZ300 and this filter has good reviews. The overall quality seems very good and the packaging works well when it is larger than necessary. The filter screws on well without affecting the fit of the hood, stows or unfolds upside down and shows no vignetting at 25mm. There doesn't seem to be any noticeable degradation in photo quality. I'll update if I find any more issues in the future, but this filter seems like a good buy.

So, I tried it out and I'm very happy with it. It was my first photo ever with the filters. I'd definitely recommend it. Best regards, Enzianhonse!

After looking at different reviews of different ND filters, zeroed it on K&F Concept VND filter.
Economical, High Performance VND filter that produces spotless long exposure photos.
I have tried waterfalls and the results are stunning.. the Special Nano Series with No X Cross produces videos and photos without any vignetting at extreme stops in broad day light.

This magnetic ND filter attaches instantly and allows precise light control with smooth rotation. The variable range covers multiple stops without color shifts or vignetting. The glass is high quality and resists fingerprints and smudges. Switching filters mid shoot is fast and secure with the magnetic system. A game changer for video and long exposure photography.

Love the magnetic filter system. They’re such a low profile. From my photo, I didn’t lose sharpness and didn’t get a color cast. I’ve already bought more and couldn’t be any happier. I’m able to stack my CPL filter without a problem. They’ve proven to be reliable. No complaints from me.

This filter will really up my photography! Some landscapes near me can be very bright and I needed a filter to adjust the brightness from the camera with ease. It comes in a nice case and the lens is constructed very well. To install, just screw it onto the lens. You can move the front of the filter up and down to adjust how much neutral density to apply. It makes taking pictures so much easier!

When I ordered the K&F variable ND filter, I wasn’t sure what to expect in terms of quality and the coloring that would be achieved when my images were rendered. However, the colors do not shift at all, and I was pleased with how nicely they pair with the Sony A7iii and A7riii. As an owner of both Polar Pro and Tiffen filters, I must say this filter is a cost-efficient product, coming in at half the cost of the Polar Pro filters I own. Even better, is that this filter has hard stops so you don't get that X when you go beyond the filter’s limit. If you're on the fence about ordering this product, I highly recommend trying it out. Below, I've added a couple images where the K&F variable ND filter was utilized- one shows the filter on my Sigma 135mm f/1.8 Art, and the other demonstrates a portrait I took while using it.

These is my 2nd variable ND from K&F. The quality it's good as Tiffen and others manufacturers. Instead of have a lot of ND of different sizes it's better have a variable ND for my photography work and save same money.
The only CONS it's the protective case that came with the ND. It's nice but too big.
