It has a good quality but not that good variable range
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.
