After only four months, the autofocus failed on my 610. I brought it to Nikon and the technician receiving the camera inspected it and told me it would be covered under warrantee. He entered my personal information, gave me the receipt, and told me he would fill out the remaining information. . . but he assured me it would be repaired under warrantee. Today i received an email claiming "impact damage" caused the problem. When i gave Nikon the camera, it had never fallen, hit anything, nor did it have any damage. IT was cosmetically new. Now i am told it was impact that caused the damage. I protested by calling Nikon and await the technician's response. I am furious, and should it be that Nikon fails to repair under warrantee, i will likely sell all my equipment. I will not continue with a company whose warrantee is worthless. If they stand by their warrantee, i will remain a Nikon user. I will let you know what happens. Has anyone had such experiences with Nikon? Any suggestions how i should proceed to protest should Nikon try to charge me about $350 for repairing my 610?
