Safety Precautions: Do not look directly or indirectly at the sun without appropriate eye protection, and do not look directly or indirectly at the sun for extended periods, even during a solar eclipse. Do not expose any lens to the sun without an appropriate filter as this could cause damage to your camera sensor. Install Solar Eclipse filter on the front of the camera lens, do not use on the optical Viewfinder. Filter is for use only with cameras and it is not suitable as eye protection. For best results we recommend that you use a tripod when shooting with this filter.
