I disagree with this, bcos seller stated that it still have 7 months manufacturer warranty (peace of mind), so the best way to test is use it. Of course, if found any problem after an agreed period of time, buyer cannot blame seller, instead claim from manufacturer, but in this case, the official warranty already voided before sold to him.
there is always a risk to buy used/demo item. dont depend so much on warranty. User must check the condition upon received. You think by having warranty give you peace of mind? you wont know whether the failure is valid or non -valid for warranty claim so put in your mind that buying used item with warranty is a bonus package not peace of mind as we dont know the 1st user how he use the lens.
Example: might be dropped but still usable so went to sell it. buyer bought it after 1 month spoil and claim warranty but rejected by center due to found internal impact damage.
