K&F Concept 46mm ND2-ND400(1-9 Stop) Filter, Variable ND Filter, Ultra-Slim/Multi Coatings, for Camera Lens

These filters are awesome! Very great value for the money. My only gripe is there's no stop when you turn to lens filter to go darker or lighter. Other than that, they are very well made and the ring is made of aluminum.

Does everything Right. No problems. Love K&F's ND filters. Bought another from them for another one of my lenses. Will definitely buy their Brand again.

No dislikes the dial on the side stops the guesswork. Coatings are superior .

This ND is a great for landscape photography especially between 1 to 6/6.5 stops. You can shoot some very interesting long exposures with it.Its also great for filmmaking but you do lose some detail in the shadows. Nothing major and great procuct overall considering the price.

the first 2-3 stops work really well, so if you don't need much depth in your shot, use this with a slower aperture and you'll get the best results you can out of it. Beyond about the 3rd stop.....you'll get some seriously unpredictable, but guaranteed every time, vingetting in the corners. Can be edited out in post - if its a photo. Its glaring apparent in video which makes it just about unusable if you're not just taking pictures. Spend the extra $100 and get a REAL variable ND.

I was using the newer sony full frame sony lens SEL24F28G. Thought it didn’t fit but I was screwing the wrong side in. It works great now.

It's easy to dial in the stop you want to use. Elevated the creativity of my coastal shots. Very happy!

I bought two of these and immediately used them for a wedding. I noticed a huge green shift right away in the footage shot with the filter. That didn't bother me much since I'm decent at color grading. What did bother me is when I looked at second shooters footage of the ceremony and it was real blurry. I initially thought she just didn't hit focus. A few days later I was shooting outside on a Tamron 70-180 and when on the long end couldn't get anything in focus. As soon as I took off the ND everything became super sharp again. Check out the screens I've included. I definitely would not recommend this to anyone. Save up for the Freewell, or Polar pro. Don't risk ruining your footage.*************************UPDATE***********************************Their customer service might be the worst I've ever encountered. I brought this up to customer service and after ten emails ....sending screenshots & video files and literally explaining to them like four times that I bought two of these and only one is super blurry so it's not anything I'm doing. They refused to do anything about it and told me that I should have bought a better ND filter. So that's the advise I'll give you, don't buy this filter.

Tiene demasiado ajuste el anillo del filtro y es innecesario
