Cry to death! I just bought Nikon D90, and the lens cover is missing. Does anyone know where to get it?

The lens cover has nothing to do with the fuselage, only with the lens. It is estimated that it is 18- 105 sets of cameras, that is, 67mm lens cover. You should sell it in photographic equipment stores or places where you buy cameras, but the original ones are more expensive, and other brands or imitations are cheaper. Just report the lens model to the merchant. Of course, if you are not at ease, you'd better take the machine with you.
