TO ENSURE LONG-TERM SATISFACTION (CON’T)
Do not touch the lens-camera interface contacts since dust, dirt and/or stains may
cause contact failure between the lens and camera.
When using your equipment [camera(s) and lens(es)] in an environment where the temper-
ature changes from one extreme to the other, make sure to put you equipment temporarily
in a case or a plastic bag for a length of time in order for the equipment to go through grad-
ual temperature change. This will also reduce potential equipment troubles.
