EYE-START
20 21
The eye-start system automatically activates the 800si’s main
systems as soon as you bring the camera to your eye. When you
set the main switch to ON, the data panel and grip sensor activate.
Touching the grip sensor activates the infrared emitter detector
located beneath the eyepiece. When an object is detected near
the viewfinder, autofocus and autoexposure immediately activate
so the camera is already operating by the time you frame your
subject.
• When an object is no longer detected near the eyepiece or you break
contact with the grip sensor while looking through the viewfinder,
autofocus and autoexposure will remain active for an additional five
seconds.
• Wearing sunglasses that absorb infrared light or gloves may affect the
operation of eye-start.

TURNING EYE-START ON/OFF
Slide the eye-start switch to ON
or to OFF.

camera by pressing the shutter-
release button partway down.
• When the camera is on, the focus
frame will appear in the viewfinder
even with eye-start off.
Customize Function #15 - Eye-start Switch
The function of eye-start switch can be changed to add a dial
lock. Dial lock is convenient when you are shooting in M, PA, or
PS mode, so an accidental turn of the control dials does not
change your shutter speed or aperture setting. Custom settings:
1 - Normal. Eye-start switch ON - Eye-start on.
Eye-start switch OFF - Eye-start off.
2 - Eye-start always on. Eye-start switch ON - dial lock on.
Eye-start switch OFF - dial lock off.
3 - Eye-start always off. Eye-start switch ON - dial lock on.
Eye-start switch OFF - dial lock off.
Customize Function #7 - Eyepiece Sensor Activation
The eyepiece sensor can be activated by the grip (standard
method) or can be activated with only the main switch set to ON.
This is convenient when you are wearing gloves or won't be
touching the grip sensor. See page 102.
