Part I: Fast Track to Super Snaps
Always attach (or switch) lenses in
a clean environment to reduce the
risk of getting dust, dirt, and other
contaminants inside the camera or
lens. Changing lenses on the beach
on a windy day, for example, isn’t a
good idea. For added safety, point
the camera body slightly down when
performing this maneuver. Doing so
helps prevent any flotsam in the air
from being drawn into the camera by
gravity.
Removing a lens
To detach a lens from the camera
body, take these steps:
1. Locate the lens-release button
on the front of the camera,
labeled in Figure 1-2.
2. Grip the rear collar of the lens.
In other words, hold onto the
stationary part of the lens that’s
closest to the camera body.
3. Press the lens-release button
while turning the lens away
from the lens-release button
(counterclockwise).
You can feel the lens release
from the mount at this point. Lift the lens off the mount to remove it.
4. Place the rear protective cap onto the back of the lens.
If you aren’t putting another lens on the camera, cover the lens mount
with the protective cap that came with your camera, too. These steps
help keep your lens and camera interior dust-free.
Using an IS (Image Stabilizer) lens
The 18–55mm lens sold with the Rebel T3/1100D camera offers image stabili-
zation. On Canon lenses, this feature is indicated by the initials
IS
in the lens
name.
