This is a Light Leak Lens from POLARPRO, designed to enjoy light leaks. It's marked as Nikon F mount, but it's actually Leica L mount. Used a few times, with no noticeable scratches or stains. The original box has some minor wear. It's fixed at F11 and for infinity focus, so it doesn't have a focus ring. Please understand this. Please understand this is a used item, and the exterior check is done by an amateur, so it's not equivalent to a new item. - Model: 28mm - Color: Black/Gold - Accessories: Lens cap Thank you for looking.
