macro and telephoto use. You can cancel the Self Timer during this 2 or 10 second
wait, before the shutter fires by pressing the Self Timer button again.
The RC-1 IR remote control is relatively inexpensive and works very well for
numerous situations. You can use it instead of the Self Timer when you want to be
in the picture, or when you want to trip the shutter without touching the camera that
would cause vibration. It also has a three position switch, off, on and 2 second delay.
The 2 second delay position is for when you are in the picture and want to hide the
remote before the exposure.

2.6 Focus Mode Switch

On the other side of the prism/flash hump you'll find the Focus mode switch and the
Film Advance switch. The Focus mode switch is on top and has three positions and of
course, only works when the lens is set to AF mode itself. In One Shot mode, as soon
as you press the shutter button half way down, the camera will autofocus and lock onto
on a subject and it stays locked at this distance as long as you continue hold the shutter
button half way down. In this mode the focus has to lock onto some distance before the
shutter will fire. This can prevent out of focus pictures as long as the subject doesn't
move towards or away from the camera.
In AI Servo mode the camera will focus on the subject but will not lock anything.
