So far from my limited testing it is a very nice filter. I have the 1/8 mist and it seems to just add a touch of softness. It also doesn't appear to introduce any strange colour casts to the image. The operation is also pleasant and smooth.

This 2-in-1 filter offers an excellent combination of Black Mist 1/8 and variable ND2-ND32, ideal for photographers and filmmakers who want to customize their exposure control and visual style. The Black Mist filter creates a gentle blur and soft look, while the ND filter allows precise exposure control to prevent overexposure. The high-quality multi-coating minimizes reflections and ensures clear, sharp images. The filter is particularly suitable for working in a variety of lighting conditions.

This filter has an 82mm thread. I have just reviewed the K&F 72mm version—it is excellent. I have also reviewed an other K&F filter with a different specification. When these filter became available for review, I jumped at the chance. Previously, I have purchased a number of K&F lenses, and I have never been disappointed.

I have three lenses with 82mm thread—FE135mm GM; FE50mm 1.2 GM & FE 24-70ii GM. I will have no compunction about using a K&F filter with these high-end lenses.

I have purchased a number of K&F filters previously, and other K&F products. I have found that its products are of excellent value and quality. I sometimes wonder whether the purported quality of higher priced filters is marketing-driven; whether it’s more about reinforcing our perceptions about the relationship between price and quality, rather than real-world performance improvements.

There are superior filters - filters with glass reclaimed from ancient Greek vases. However, this combination filter will serve me swimmingly. I mightn’t even be able to tell the difference.

You’re getting a lot of performance from this filter at a very reasonable price. It’s a precision-built filter with flawless engineering. All K&F filters come with a sturdy, light case, and three cleaning clothes.

I'm a big fan and loyal user of the K&F concept brand. We all know that photography, both as a profession and even as a hobby, isn't exactly a cheap art. If you spend a lot of money on a good lens, it's only logical that you wouldn't waste it on cheap, low-quality filters. I think this brand strikes a perfect balance between quality and affordability because, without selling overpriced materials, it actually offers very good quality products, as is the case with this 2-in-1 filter.

I'm more of a videographer than a photographer, and the truth is that with this filter, the scene gains a cinematic feel, which, in my case, is much appreciated. For photography, since it's variable (turning the ring changes the density very easily), it's a great option for both shooting on sunny days, using polarizing functions, and for long exposures.

I really think its construction is very good. You can tell it's not plastic and the materials are carefully selected, and it comes protected in a very practical carrying case. So as always with this brand, I am very satisfied.
