Safety Precautions
• Do not look at the sun or a bright light source
through the lens or camera.Doingsocouldresult

thelensisespeciallyhazardous.
• Whether it is attached to the camera or not, do
not leave the lens under the sun without the

a warm one, condensation may develop on the
lens surface and internal parts.Toprevent
condensationinthiscase,firstputthelensintoan
airtightplasticbagbeforetakingitfromacoldto
warmenvironment.Thentakeoutthelensafterit

thelensfromawarmenvironmentintoacoldone.
• Donotleavethelensinexcessiveheatsuchasin
acarindirectsunlight.High temperatures can
cause the lens to malfunction.
