Attaching And Detaching A Lens; Zoom - Canon EOS 70DW Instruction Manual

Zooming
Detaching the Lens
To owners of the EF-S 18-200mm f/3.5-5.6 IS lens:
Do not look at the sun directly through any lens. Doing so may cause
loss of vision.
When attaching or detaching a lens, set the camera's power switch to
<2>.
If the front part (focusing ring) of the lens rotates during autofocusing, do
not touch the rotating part.
If you purchased a lens kit with the EF-S 18-55mm f/3.5-5.6 IS STM
or EF-S 18-135mm f/3.5-5.6 IS STM lens, see "Handling
Precautions" on page 443.

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.
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.
