I am selling this item because I received it from my grandfather but do not use it. It was stored in a dehumidified storage unit for approximately 1.5 years after I received it. Operation has been confirmed. Dust can be seen inside the lens. I believe it is to the extent that it does not affect shooting. There is no mold or clouding. HAKUBA lens filter included. This is based on my personal assessment. Please purchase only if you understand this.
