Unfortunately, this model is a fixed lens camera, which means the lens is not replaceable without full disassembly, and that replacement lenses aren’t available directly. You can take it to an approved [https://www.nikonusa.com/en/service-and-support/service-and-repair.page|“authorized repair station” or send it to nikon directly], but you will have to pay since it’s out of warranty, and that’s if they still have replacement lenses available. Make sure to inspect any cameras you buy secondhand thoroughly from now on, people sell them damaged very frequently.
