Normally, after focus is achieved and the
shutter button is pressed completely, the
shutter release time lag is fixed at 55 ms.
This is the time it takes for the aperture to
stop down by 3 stops. However, when
the aperture stops down by fewer than 3
stops, the shutter release time lag can be
shortened by as much as about 20 per-
cent.
This reverses the electronic dial's setting
(rotation) direction. The sequence for
selecting a focusing point and setting the
shutter speed or aperture will be reversed
when the dial is turned.
This can be set individually for the Main
Dial and Quick Control Dial.
Even if the Main Dial's rotation function is
reversed, the rotation direction for select-
ing a focusing point remains the same.
Setting exposure compensation with the
Quick Control Dial is disabled.
This can be set to 1 to 20 rolls of film.
When the remaining memory capacity
can store the shooting data only for this
number of rolls, the communications icon
blinks on the LCD panel as a warning.
The film ID imprinting can be made dark-
er or lighter by about one stop.
This increases the chances of Since the difference will only be 10

to sense the difference.
With C.Fn-11-2 set and the Power
Drive Booster attached during ver-
tical shooting, selecting the focus-
ing point with the Quick Control
Dial might not match the dial's
rotation direction (the same goes
for the exposure level movement).
This Personal Function remedies
this.
Rotation direction during vertical
shooting with P.Fn-27 not set.
This prevents exposure compen-
sation from being set accidentally
while the focusing point is being
selected.
This prevents previous shooting
data from being overwritten when
the memory capacity becomes
full.
This is effective when you want to
match the imprinting density with
the film type.
