I don't see an issue with it in general if it's well disclosed.
In this case it is disclosed, but I don't think it should be an 'excellent' rating.

Me too, but they sell them. So where do they get them from?I had a Fuji 18-135 declined by MPB due to fungus internally.
at a guess.... they dont spot it when they buy it... until they come to list the item and realise it has fungus and then still try and sell it for an over the top price.Me too, but they sell them. So where do they get them from?
But in no way can it be described as 'Excellent' - even by their standards!I can't see anything wrong with a dealer selling second hand goods in any condition, provided they behave within the provisions of the Consumer Rights Act 2015...
Consumer Rights Act 2015
An Act to amend the law relating to the rights of consumers and protection of their interests; to make provision about investigatory powers for enforcing the regulation of traders; to make provision about private actions in competition law and the Competition Appeal Tribunal; and for connected...www.legislation.gov.uk
There are three basic rules, which are the goods should be:
If they tell you there's fungus or any other defect and the lens works otherwise, then it's up to you to decide whether to buy or not.
- fit for the purpose the item was sold for
- of satisfactory quality
- as described in any advert, marketing materials or seller's explanation.
I've had plenty of pleasing images from lenses that have fungus and/or other defects.

I really think that would be something that only a court case, costly for all concerned, could decide on.But in no way can it be described as 'Excellent' - even by their standards!
"Optics are clear" ??????????/I really think that would be something that only a court case, costly for all concerned, could decide on.
It would come down to whether the judge decided that the description would be agreed with by an "average" customer. In any case, if the seller offers a cost free return service, the customer would have no possible complaint.
Exactly.So long as you know that is what you are buying then it's up to you to buy or not.
