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.

bag before taking it from a cold to warm environment. Then take out the lens

after it has warmed gradually. Do the same when taking the lens from a warm

environment into a cold one.
