K&F Concept may not be the most famous brand in the world but this particular filter works wonders, and I was skeptical about the combined effect because usually these two-in-one things don't usually work well.

The glass has a very subtle matte finish that when you look at it up close it seems to be tarnished, but it is precisely this effect that softens the high lights without destroying the image. The best thing is that you don't have to go around removing and putting different filters depending on what you need, this one does both things at the same time and the result is very natural, nothing exaggerated. In the portraits I have taken these days, you can see a lot of difference, wrinkles and skin imperfections are softened but without giving that plasticized look that some cheap filters give, and the lights have that beautiful cinematic glow that is so fashionable now.

The filter creeps smoothly into my 67mm lens and I haven't noticed vignetting or anything unusual, although it's true that the overall contrast drops a bit, but that can even be an advantage depending on what you're looking for. The only thing I didn't like very much is that when I combine it with my variable ND filter, sometimes strange reflections appear, but hey, that happens with almost all filters when you stack them. The box it comes in is great for keeping it protected in the backpack without fear of being scratched.
