Canon EOS DIGITAL REBEL XTI Mirror Lockup, Shooting Tips, Do not point the camera toward the sun

Preventing Camera Shake

Mirror Lockup

Although remote control shooting can prevent camera shake, using mirror lockup to prevent camera vibrations can also help when you use a super telephoto lens or shoot close ups. Mirror lockup is enabled by accessing [bCustom Function (C.Fn)] and setting [Mirror lockup] (p.105) to [1:Enable].

Press the shutter button completely to lockup the reflex mirror.

Then press the shutter button completely again to take the picture. The reflex mirror will then go back down.

Shooting Tips

Do not point the camera toward the sun.

The sun’s heat can scorch and damage the shutter curtains.

With the self-timer, the picture can be taken after a 2-sec. delay. When you press the shutter button completely, the mirror locks up, then the picture is taken 2 sec. later. For bulb exposures, hold down the shutter button until you want to end the exposure. If you let go of the shutter button during the 2-sec.self-timer countdown, there will be a shutter- release sound. This is not the actual shutter release (no picture is taken).

Remote control shooting

Since you do not touch the camera when the picture is taken, remote control shooting together with mirror lockup can further prevent camera shake. With Remote Controller RC-5, pressing the transmit button locks up the mirror before the shot is taken 2 sec. later. With RC-1, set it to 2-sec. delay, then shoot.

If <i> (Continuous shooting) has been set, single shooting will still take effect. The mirror locks up, and after 30 seconds, it will go back down automatically. Pressing the shutter button completely again locks up the mirror again.
