K&F CONCEPT NANO-X Variable ND Filter (72mm). I mainly used this for video shooting. The rotating action is smooth, and there are no problems with its ND functionality. ■ Condition There are scratches and coating unevenness on the glass surface due to use (see photos). I didn't feel any adverse effects during actual use, but I've priced it considering the condition. * No cracks, chips, or malfunctions of the ND mechanism. ■ Included Items ・Filter body only (No original box or case) ■ Other ・Instant purchase OK ・No returns accepted Please purchase only if you understand the condition.
