Precautions for Use
• Do not pick up or hold the lens or camera using only the lens caps or lens
hood.
• Keep the CPU contacts clean.
• Reattach the lens caps when the lens is not in use.
• Do not leave the lens in humid locations or in locations in which it may be
exposed to moisture. Rusting of the internal mechanism can cause irreparable
damage.
• Do not leave the lens next to open flames or in other extremely hot locations.
Extreme heat could damage or warp the lens.
• Taking the lens from a warm to a cold environment or vice versa may cause
damaging condensation inside and outside the lens. Place the lens in a sealed
bag or plastic case before taking it across a temperature boundary. The lens can
be taken from the bag or case once it has had time to adjust to the new
temperature.
• We recommend that you place the lens in a case (available separately) to
protect it from scratches during transport.
