KANI Square Filter Premium Reverse GND 0.9 100x150mm (Reverse Half ND8) *No box or instruction manual. Used for about a year. I used it with care and it was very useful for key shots. It allowed me to challenge landscape photography, which I had given up on before, and it's a filter that made me want to improve my skills. I am selling it because I will be taking a break from shooting for a while. The case shows signs of use. There are no other major noticeable scratches, but please consider this item as used. [From the product description] The filter has a light reduction effect on half of its surface, with a weaker effect at the top edge and stronger towards the center, a gradation specification. The maximum light reduction effect is ND8. Useful for shooting with the sun in the shot before sunset and after sunrise.
