Mounting on the Camera and Dismounting

Pre-Mounting Checklist

1.Make sure the camera's stop-down lever is not locked for stopped-down metering (see p. 61). If it is, a red warning dot will appear beside the coupling lever inside the camera body.

2.Make sure the automatic aperture lever at the rear of an FD lens is not set for manual diaphragm control (see p. 80).

3.Before mounting an FD lens, make sure the film advance lever has been complete- ly advanced.

4.Remove the lens' rear dust cap.

5.Remove the camera's body cap.

In the case of an FD lens which lacks a chrome Breech-lock mount ring:

Mounting

1.Align the projecting red mount position-

ing point on the lens with the red dot –16–

above the camera mount.

2.In this position, apply slight pressure to the lens, and simply rotate the whole lens clockwise until it stops and the lens release button pops out with a click.

Do not press the lens release button while mounting the lens.

Only when this button pops out can you be sure that the lens is properly mounted and that it will function properly. It is also possible to mount this type of lens when it is not perfectly aligned with this camera. To facilitate mounting when it is very dark or when you are in a great hurry, the mount positioning point is rounded. Simply find this point with your finger and align it as closely as possible with the red dot on the camera. Turn the lens slightly back and forth while applying slight pressure until it drops into position and continue with step 2 above. Excessive sloppiness will make mounting impossible; take care to be as accurate as possible.

Dismounting

1.Turn the lens counterclockwise until it stops while pressing the lens release button.

2.Pull the lens out.

When the lens is dismounted, the diaphragm blades are locked in a half-closed position and will not move even if you turn the

lensaperturering.
