I ordered a used Canon
I ordered a used Canon EF-S 55-250mm f/4-5. 6 IS STM from Gosselin's used department (Order #2000122268, June 4, 2026, $247. 47 with tax), listed as Condition 8. It arrived with obvious impact damage: the front ring is dented, and the filter thread is bent badly enough that no filter will screw on at all. That is not "moderate wear" - that is a lens with an obvious functional defect, and the impact was hard enough to bend the filter ring.
I've returned it for a full refund. However, if you buy used gear from Gosselin - inspect everything the day it arrives.
Update: Gosselin's own reply states a filter could be installed "with more effort than normal. " A filter thread that needs more than normal force to accept a filter is exactly the defect - that is not Condition 8 in my opinion.
