didnt come eith a warrenty i bought them at the pawn shop and the previous user voided the warrenty it mgith be the problem.
Actually, if you sent them back to Nikon with a brief note explaining the problem and a check payable for $10 plus shipping then they will fix them for you. Nikon's policy is that without a receipt/warranty card there is a $10 fee to fix any problems with the bins.
As the others have made reference to the Monarchs are the best bang for the buck going today. Want more proof? Check out the link below. It is to a comprehensive review of current binoculars on the market separated by price. It was done by the Cornell Lab of Ornitholgy and if anybody is picky about their optics it is birders.
Hope this helps.
