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.
Conventions used in this instruction
Warning to prevent lens or camera malfunction or damage.
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
●❶
. To remove it, reverse the order.
2. Setting the Focus Mode
To shoot in autofocus (AF) mode, set the focus mode switch to AF
❷
.
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
❸
.
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.
