I am a paid photographer in the church where I worship. We are Four in our department. And I am the most experience which gave me the opportunity to always buy our cameras {all Nikon products} For some time now we have been having problem with regards the Lens I bought. They always get bad before the period of warranty our supplier usually gave us [6 months]. And my colleagues always denied that they just get bad on it's own. And My supplier is saying that they got damage because of lack of proper care.So What could be the causes of the damages of our Lens?
