Mirror lockup lever
When using super-telephoto lenses or doing photomicrography, it becomes necessary to reduce camera vibration
to the absolute minimum. To lock the reflex viewing mirror in the "up" position, push in the depth-of-field
preview button and rotate the lever counterclockwise until it stops.
Note: Two Nikkor lenses require that the mirror be locked up before mounting – the Fisheye Nikkor 6mm
f/5.6 and OP Fisheye Nikhor 10mm f/5.6.
Caution: With the mirror locked up, you should not operate the camera on automatic. Even though the LCD
continues to show you the shutter speed automatically selected by the camera, this speed will not produce the
correct exposure.
Self-timer
The F3 High-Eyepoint camera's blinking self-timer provides a 10 sec. delay in shutter release.
To operate the self-timer:
1. Push the self-timer lever to uncover the red dot .
