Hello Guys, I got a Nikon D50 body and went to the dealer to get a 18-55mm, 55-200mm and 50mm f 1.8. But the problem is my dealer says that there is some problem with the 18-55mm Nikkor lens that it stops functioning after a few months of usage. He claims that it's due to some problem in the electronics embedded in the lens. Is it correct? Please suggest me. Thanking you, amiably, Ravi Kiran.
