Thank you for viewing. Please check the description section (^^) SMC Pentax 6x7 lens, 45mm F4, for Pentax medium format film cameras I have confirmed the overall operation. The lens condition is very clean, and I believe there are no scratches or mold when viewed through a fluorescent light. There is no oil stain either. The exterior has minor scratches, and I think it's in relatively good condition. No claims No returns Serial number 8513950 Thank you.
