Precautions for Shooting ●● If dirt or dust adheres to the surface of the front lens element, it can easily appear in images due to the lens's short focal length. In order to avoid this, please remove dirt or dust from the surface of the front lens element by using a commercially available air dust blower. ●● Since this lens has a wide angle of view, light from bright light sources, such as the sun, can easily enter the image area. Please do not look at bright light sources using the camera's viewfinder. ●● Similarly, flare and ghost will occur when bright light sources appear in the image area, depending on shooting conditions. In order to prevent flare and ghost, we suggest shooting places such as shaded are as so that bright light does not enter the lens. ENG-3
