Safety Precautions
1.Do not look at the sun or a bright light source through the lens or camera. Doing so could result in loss of vision. Looking at the sun directly through the lens is especially hazardous.
2.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.
Handling Cautions
If the lens is taken from a cold environment into 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 has warmed gradually. Do the same when taking the lens from a warm environment into a cold one.
1. Mounting and Detaching the Lens
See your camera’s instructions for details on mounting and detaching the lens.
•After detaching the lens, place the lens with the rear end up to prevent the lens surface and contacts from getting scratched.
•If the contacts get soiled, scratched, or have fingerprints on them, corrosion or faulty connections can result. The camera and lens may not operate properly.
•If the contacts get soiled or have fingerprints on them, clean them with a soft cloth.
•If you remove the lens, cover it with the dust cap. To attach it properly, align the lens mount index and the index of the dust cap as shown in diagram ❶ , and turn clockwise. To remove it, reverse the order.
2. Setting the Focus Mode
To shoot in autofocus (AF) mode, set the focus mode switch to AF ❹ .
To shoot in manual focus (MF) mode, set the focus mode switch to MF, and focus by turning the focusing ring.
