Need opinion on "as advertised" issue with camera lens
I sold a 150mm f3.5 mamiya lens that I just had lying around for a while. It went to a buyer in South Korea and shipped from the east coast USA. It took maybe about a month to get to SK. In my opinion, it was clean, I made sure it was wiped down before shipping, the glass was very clean.
The listing states that the glass “appears clean and clear with no obvious fungus, haze, scratches, or separation when inspected under normal lighting. Please review all photos carefully as they are part of the description and represent the exact item being sold.
As with any vintage photographic equipment, this item is being sold in used condition. While it appears to function as intended, no guarantees are made regarding long-term performance due to the age of the equipment"
I take this very seriously and am not here to be scamming people on cameras lenses as I have been scammed on lens condition before.
The buyer states - "I noticed a large number of small white spots distributed throughout the glass.
I used a bright light in the attached photos simply to make the issue easier to photograph, but the spots are also visible to the naked eye when the lens is held up to ordinary indoor lightingSo this is not something that is only visible under an unusually strong flashlight inspection."
They are asking for a partial refund for this.
In my opinion, it is not my responsibility for what happens to it on the one month journey that it took to get there.
Right hand to God, that is not the condition that I sent it out in. It was very very clean and what they are claiming is not the condition it was sent in..
Please let me know your thoughts and how I should proceed. (I have sold like 4 things ever on ebay, this is not a business for me)
First pics are mine, then the buyers
listing photos are not touched up or altered in any way. That is how they came out on my camera
