Attaching and Detaching a Lens
Turn the zoom ring on the lens 
with your fingers.
 If you want to zoom, do it before focusing. Turning the zoom ring after 
achieving focus may throw off the 
focus.
While pressing the lens release 
button, turn the lens as shown by 
the arrows.
  Turn the lens until it stops, then 
detach it.
  Attach the rear lens cap to the 
detached lens.
  To owners of the EF-S18-200mm f/3.5-5.6 IS lens:
You can prevent the lens from extending 
out while you are carrying it around. Set 
the zoom ring to the 18mm wide-angle 
end, then slide the zoom ring lock lever 
to < LOCK>. The zoom ring can be 
locked only at the wide-angle end.

loss of vision.
  When attaching or detaching a lens,  set the camera’s power switch to 
.

A lens hood can block unwanted light and diminish rain, snow, dust etc. 
adhering to the front of the lens. Befo re storing the lens in a bag, etc., 
you can attach the hood in reverse.
  If the Lens and the Lens  Hood Have a Mount Index
1Align the red dots on the hood 
and lens edges, then turn the 
hood as shown by the arrow.
2Turn the hood as shown in the 
illustration.
 Turn the hood clockwise until it 
attaches securely.
Attaching a Lens Hood
Image Conversion Factor
Since the image sensor size is 
smaller than the 35mm film 
format, it will lo ok like the lens 
focal length is  increased by 
approx. 1.6x.Image sensor size (Approx.) (22.5 x 15.0 mm / 0.88 x 0.59 in.)
35mm image size 
(36 x 24 mm / 1.42 x 0.94 in.)
  If you do not attach th e hood properly, it may obstruct the image’s 
periphery, making it look dark.
  When attaching or detachi ng the hood, grasp the base of the hood when 
turning it. Grasping the  hood’s edges when turning it may deform the 
hood, resulting in failure to turn.

When you use the IS lens’ built-in Image Stabilizer, camera shake is 
corrected to obtain a sharper shot. The procedure explained here is 
based on the EF-S18-135mm f/3.5-5.6 IS STM lens as an example.
* IS stands for Image Stabilizer.
1Set the IS switch to .
 Also set the camera’s power switch to 
.
2Press the shutter button halfway.
XThe Image Stabilizer will operate.
3Take the picture.
  When the picture looks steady in the 
viewfinder, press the shutter button 
completely to take the picture.
Lens Image Stabilizer
 The Image Stabilizer cannot correct  “subject blur”, when the subject 
moves at the time of exposure.
  For bulb exposures, se t the IS switch to . If < 1> is set, Image 
Stabilizer misoperation may occur.
  The Image Stabilizer may no t be effective for excessive shaking such as 
on a rocking boat.
  The Image Stabilizer can operate with  the lens focus mode switch set to 
either  or .
  When using a tripod, you  can still shoot with the IS switch set to  
with no problem. However,  to save battery power, setting the IS switch to 
 is recommended.
  The Image Stabilizer is effective ev en when the camera is mounted on a 
monopod.
  Some IS lenses enable y ou to switch the IS mode manually to suit the 
shooting conditions. However, the fo llowing lenses switch the IS mode 
automatically:
• EF-S18-55mm f/3.5-5.6 IS STM •  EF-S18-135mm f/3.5-5.6 IS STM
• EF-S18-200mm f/3.5-5.6 IS

Preventing Camera Shake
Hand-held camera movement during th e moment of exposure is called 
camera shake. It can cause blurred pictures. To prevent camera shake, 
note the following:
• Hold and steady the camera as shown on the preceding page.
• Press the shutter button halfway to  autofocus, then slowly press the 
shutter button completely.

pressing the shut ter button halfway.
 
If you press the shutter button completely  without pressing it halfway first, 
or if you press the shutter button halfway and then press it completely 
immediately, the camera will take a moment before it takes the picture.
