❶Thank you for purchasing a Canon product.EF50mm f/1.8 STM is a compact, lightweight, low-profile high quality standard 
lens.
● “STM” stands for Stepping Motor.
 Safety Precautions● 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.● 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 en vironment 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.
● Do not leave the lens in excessive heat such as in a car in direct sunlight.  
High temperatures can cause the lens to malfunction.

firmware. If the camera’s firmware is not the latest version, be sure to update
