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 arrow.
 Turn the lens until it stops, then detach it.
 Attach the rear lens cap to the
detached lens.
Zooming
Detaching the Lens
 Do not look at the sun directly through any lens. Doing so may cause
loss of vision.
 When attaching or detaching a lens, turn off the camera power.
 If the front part (focusing ring) of the lens rotates during autofocusing, do
not touch the rotating part.
 If you use a TS-E lens, certain shift and rotation functions may be
restricted, and attaching or detaching the lens may also be restricted.
 If you use a TS-E lens and shift or tilt the lens or use an Extension Tube,
the standard exposure may not be obtained or the exposure may be
irregular.
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.
