Just wondering; if selling an expensive lens with an expired official warranty, should the seller provide a personal warranty, and what should that personal warranty cover? In my opinion, not sure if right or wrong, the seller should provide 3-5 days personal warranty for problems relating to:
1. focusing problems
2. mechanism/AF/VR etc problems
3. fungus (after all, fungus won't grow till so jialat in 5 days, right?)
but not cover things like scratches to lens elements, dents and scratches.
Also, if the buyer is unsure, he can at his own expense, pay for a general checkup of the lens at the authorised service center. If there is indeed a problem, then the seller will either bear the cost of repairs/servicing or give a full refund. If there's no problems then the buyer will have to foot the bill for his uncertainty.
What do you guys think?
