If your lens is not working, your pictures will not turn out.
Camera lenses are an integral component of your camera. Before any image is recorded on the film or digital sensor, it must pass through the lens. Whether you have a point and shoot or single lens reflex model, your pictures are not going to turn out if your lens is not working. There is not a lot you can do yourself to repair point and shoot camera lenses. Other than cleaning the front glass element and inspecting for debris, lenses should be serviced by a technician. If you have an SLR, you may be able to fix your lens.
Instructions
1. Press the lens locking button, rotate the lens and remove the lens from your single lens reflex camera. If you are using a digital SLR, place a body cap on the camera to prevent dust from entering it.
2. Inspect the lens thoroughly by looking through the lens from both the front and rear of the lens. You are looking for any foreign debris inside the lens or any indication that part of the lens has become loose and is impeding its operation.
3. Clean the electrical contacts on the rear of the lens. Any auto-focus lens relies on electrical signals from the camera to work properly. It may affect the lens performance if these contacts are dirty. Clean the contacts using a cotton swab moistened with rubbing alcohol. Dry the contacts using a microfiber lens cloth.
4. Inspect the lens barrel and the small gaps between the outer lens barrel and the barrel containing the lens elements. Small debris can become lodged in here and may affect lens performance. Remove the debris using a small needle. Do not use compressed air as this may cause the sand or debris to become further lodged inside the lens.
5. Reconnect the lens to the camera.
