Safety Precautions Precautions to ensure that the camera is used safely. Read these precautions thoroughly. Make sure all details are observed in order to prevent risks and injury to the user and other people. Warning Details pertaining to risks that may result in death or serious injury. ●● Do not look at the sun or a bright light source through the lens or single-lens reflex camera. Doing so could result in loss of vision. Looking at the sun directly through the lens is especially hazardous. ●● Do not point the lens or camera at the sun or photograph it.

This is to prevent the lens from concentrating the sun's rays, which could cause a fire.

This may result in the camera becoming excessively hot or cold, which may cause burns or other injuries when touched. Caution Details pertaining to risks that may result in damage to property. ●● Do not leave the lens in excessive heat such as in a car in direct sunlight.
