Attaching and Detaching a Lens
48
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 arrow.
Turn the lens until it stops, then detach it.
Attach the rear lens cap to the
detached lens.
To owners of the EF-S18-135mm f/3.5-5.6 IS STM lens or
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.

not touch the rotating part.

Angle of View
Since the image sensor size is smaller
than the 35mm film format, the angle
of view of an attached lens will be
equivalent to that of a lens with approx.
1.6x of the focal length indicated.
