I tested it and it gives a good image quality, effectively not showing the x shadow. As a polarizer it gives what is expected. After getting used to the way of adjusting the mounting ring, polarizer ring and ND variation knobs it is alright. I mounted it on a canon 15-85mm, f3.5-5.6 USM with no problems.
The only disapointing issue is that i could measure the range of ND variation and it is not 4 stops (ND2 to ND32). I expected a 16 times light filtering variation but i got just 10 times. At same ambient and exposure conditions the shutter speed of my canon 90D changed 1 to 10 times slower. Just a little above 3 stops.
Despite, it is still a good quality and value for money having a double funtion.

No le puedo dar 5 estrellas porque no estoy acostumbrado a trabajar con otros filtros variables para compararlo con ellos pero la construcción y la calidad de imagen que me ha dado este me obligan a recomendarlo. Entiendo que habrá mejores opciones pero desde luego este filtro no tiene nada que envidiar a la calidad de algunos fijos de más renombre que he probado. Cristales de buena calidad y construcción realmente buena.

52mm ND2-ND32 (1-5 Stop) Variable ND Filter and CPL Circular Polarizing Filter 2 in 1 for Camera Lens. What can I say about it? Exceptional. Having the ability to simultaneously adjust the ND filter and polarization without swapping out filters is super convenient. Quick adjustments can make a big difference in whether you get that perfect shot or video pan in the moment. I have a Sony ZV-1 with a 52mm adapter for lens and it seamlessly and smoothly threads on without issue. Although my camera come with a build in ND filter. The K&F takes it even further by along more control of how much light my camera takes in. The polarization aspect of the K&F further expanses on the quality of the picture. Overall, I’m extremely happy with this product.

Greatest results with this filter, I don’t see vignettes in the corners and the Quality don’t be affected.

Love this product as it allows me to shoot wide open using strobes in my studio. The product does not feel plastic(ky). Only downside to it is I can use my lens hood on it due to the size of the filter.

They worked great. It's nice being able to change darkness. The only bad thing is I didn't have it screwed on tight and it fell off. I then stepped on it while hiking and scratch them up. I did get some great pictures while hiking with it. I would definitely buy it again.

Not one of the very expensive filters but does its job as intended. If you want pro quality then look elsewhere. However for a hobbyist, not a bad starting point without breaking the bank.
