Thank you for purchasing a Canon product.
EF24mm f/2.8 IS USM and EF28mm f/2.8 IS USM are compact, wide-angle 
single focus lenses that provide high image quality.
 “IS” stands for Image Stabilizer.
 “USM” stands for Ultrasonic 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 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.
 Do not leave the lens in excessive heat such as in a car in direct sunlight. 
High temperatures can cause the lens to malfunction.

Supplementary notes on using the lens and taking pictures.
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, 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 
.
To shoot in manual focus (MF) mode, set the focus mode switch to MF, and focus 
by turning the focusing ring. The focusing ring always works, regardless of the 
focus mode 
.
After autofocusing in ONE SHOT AF mode, focus manually by pressing 
the shutter button halfway and turning the focusing ring. (Full-time manual 
focus)
3. Infinity Compensation Mark
To compensate for shifting of the infinity focus point that results from changes in 
temperature.  
The infinity position at normal temperature is the point at which the vertical line of 
the distance scale L mark is aligned with the distance index 
❹ .
For accurate manual focusing of subjects at infinity, look through the 
viewfinder or look at the magnified image* on the LCD screen while 
rotating the focusing ring.
* For cameras with Live View shooting capability.
