I think the prices got re. I have to go back and look at the numbers I posted, two of the lenses were the very expensive ones, the 85 1.2 II and the 14 2.8 II.
well..regardless of the value of these "L" lens, used value is fair at 80% to 85% of current retail price. If more than that, the bargain is no longer on the table for the buyer.
I agree that as the seller, you can list the price as much as you want but how long and who will buy it at your high price is another issue.
typical used price for your 85L mkII: $1400 to $1500 and 14L mkII around $1500.
