Jennifer Ruiz try to clean the contacts between the lens and the body carefully with a soft cloth. Make sure that the pins that make contact, are not bend. Sometimes it will reset if you remove the lens and then the battery. Leave the battery out for an hour or so. You could also check to see if you can reset your camera to factory defaults once the lens is removed. Of course, always make sure that you have a fully charged battery.

If you have another lens you could try to check that out. It could be (worst case scenario) a bad lens. It might help if you can let us know what lens you have (SELP1650?)

Consider attaching some images of the lens etc. With your question. That would allow us to see what you see. Use this guide for that
