Lifetime warranty on Nikon -Yep send to them and they will fix em for sure. If you take em back to where you bought em, it should be over the counter exchange NO QUESTIONS ASKED. Over the past 10 years I have sold HUNDREDS of nikon products-double vision can occur, but it is definately an exception to the rule. Nikon does make a superior and affordable product. If your dealer won't over the counter exchange, get me the store name and I'll get the warranty address for you via private message. M350 OUT
