I purchased the Nikon Zf last April, and I obtained this product the following month. I have lost the receipt and instruction manual from when I purchased it, but I haven't used it much, and overall, it's in good condition with little sign of use. I am selling the Zf body to organize my equipment, so I am also listing this item. Please purchase only if you understand that this is a used item. To prevent swapping, returns and refunds are not accepted after purchase. - Brand: TECHART - Features: Mount Adapter Thank you for looking.
