Removing an EF Lens

1 Turn off the camera.
• If an EF Cinema lens is connected to the camera's LENS
terminal, disconnect the 12-pin cable after turning off
the camera.

camera on or off, connect or disconnect the power
cable.

mount handle clockwise until it stops and remove the
lens.
• Make sure not to drop the lens when removing it.

dust caps back on the lens.
NOTES
• About using an EF-S lens or compatible EF Cinema lens: This camera's sensor is larger than the sensor size for which
these lenses are designed (APS-C or Super 35mm). When using these lenses with the camera, you may
notice peripheral illumination fall-off or vignetting. To prevent this, you can use the [EF-S Lens] setting to
change the sensor area that is used for producing the image (A Network Operation Guide or Button
Operation Guide). This setting digitally enlarges the image by a factor of approx. 1.55 so the image quality
will deteriorate.
• Depending on the lens's characteristics, the corners of the picture may seem darker due to light fall-off or
illumination drop. You can have the camera compensate if it has the correction data available for the lens
(A Network Operation Guide or Button Operation Guide).
• If you are using a compatible lens*, you can use the [Camera Setup] > [Zoom-Iris Correct.] setting to have
the camera adjust the aperture while zooming** (A Button Operation Guide).
* Some EF lenses and EF Cinema lenses are not compatible with this function.
** This setting is available only by using the buttons.
