 Safety Precautions
●●Do not look at the sun or a bright light source

loss of vision. Looking at the sun directly through the

●● Whether it is attached to the camera or not, do not 
leave the lens under the sun without the lens cap 
attached.  This is to prevent the lens from concentrating 
the sun’s rays, which could cause a fire.
