Attaching and removing
To attach the teleconverter
1 Remove the camera body cap, rear lens cap, and
teleconverter’s front and rear lens caps.
To remove the teleconverter’s caps, turn the front and rear lens caps
counterclockwise.
2 Align the mounting index on the lens barrel with the orange
lens mounting index on the teleconverter. Insert the lens into
the teleconverter mount and turn it clockwise until it locks into
place.
• Do not press the lens release on the teleconverter when mounting the lens.
The lens will not couple properly.
• Do not insert the lens at an angle.
3 Align the mounting index for camera body on the
teleconverter with the orange index on the camera. Insert the
teleconverter into the camera mount and turn it clockwise
until it locks into place.
• Do not press the lens release button on the camera when mounting the
teleconverter. The teleconverter will not couple properly.
• Do not insert the teleconverter at an angle.
• Always attach the lens to the teleconverter before attaching the
teleconverter to the camera. Attaching them in reverse order
may result in incorrect metering.
• Do not use more than one teleconverter with a lens. Damage
may result.
To remove the teleconverter
1 Hold down the lens release button on the camera body and
turn the teleconverter and lens counterclockwise until they
stop. Carefully lift the teleconverter out of the camera mount.
2 Hold down the lens release on the teleconverter and turn the
lens counterclockwise until it stops. Carefully lift the lens out
of the teleconverter mount.

Notes on shooting
While the teleconverter increases the focal length of the attached lens,
it reduces the effective aperture of the attached lens.* The camera’s
TTL metering compensates for the effective aperture automatically.
The teleconverter does not affect the lens’ distance scale; it can be read
in the normal way. The lens’ depth of field is shallower when using the
teleconverter.*
* See the following specifications for further information.
• Because of the increase in focal length and decrease in effective aperture, use a
tripod to reduce camera shake.
• In low light conditions, such as with dim fluorescent light, the camera may not
be able to focus. Use focus lock on high contrast subject or manual focus.
