You get color cast, but it's a lot better than Neewer, which came broken

Great product. Just as described in the literature. Very well packaged and arrived on time

Bought this to photograph the eclipse. Worked well for that. 4/5 due to the lack of stops, and lack of marks/etching to indicate approx ND level. Like I said, worked well, but if you want any idea of what your actual exposure values are you'll need to mark it ahead of time at a minimum.

A decent, cheap variable ND filter. If you're in a bind and need a backup, or are not needing for a high-end image, I can recommend this filter.The threaded ring seats nicely to my Sigma Art 24-105 and the build feels of good quality. The filter ring rotates with smooth and firm action.Sweeping through the density range we see a noticeable shift in image clarity with a bit of increasing distortion as we reach the higher density. At its maximum density there is prominent gradation in the visible light. Maximum density is achieved strongly through a center band of the image leaving the top and bottom edge (depending on how your filter seats) a few stops shy.I have not yet tested it in a studio setting with measured or metered light, but in general outdoor use these symptoms where noticeable. If you're looking to start using a ND filter and do not want to cough up $100 of more dollars for a higher end brand, this will do the trick, but with a few hangups along the way.

the product was exactly as described. When its too bright, it produces a flare in the images but otherwise works amazing! makes the color pop and gives an amazing quality.

The design make it look nice and slim. I haven't used it but there is dust in between the glasses, cannot get it out of cause. There is no way to contact the seller.Seller made the contact by replying to my review and offered a replacement, which they did. The built quality again is good and looks nice and slim. They said it is double threaded but the front one is too big (around 86mm in diameter). The front lens cap (this is used on Canon 24-70) won't sit on at all.
