Canon lens EF 50mm f18 II User Manual

							Thank you for purchasing a Canon product.
 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 CautionsIf 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 LensSee 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 
 ^, 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  a.
To shoot in manual focus (MF) mode, set the focus mode 
switch to MF, and focus by turning the focusing ring.
•  Do not touch the rotating parts of the lens while AF is  active.
•  Do not focus in MF when the focus mode switch is set to  AF.
