(smallest number) and the camera will automatically select the fastest shutter speed

setting that will still provide the correct exposure. While in Av mode, you can also

use the QCD to change/bias the exposureup or down (AEC). This is only the ambient

exposurebias and itdoes not effect the ﬂash exposure.

In P,Av or Tv modes, a blinking aperture or shutter indicator may mean that it is

out of its available range. So if your aperture is blinking f/5.6 and that is the lens’s

largest aperture, you will haveto select a slower shutter speed to bring the required

aperturein line withyour lens’savailable aperture. Alsoif 4000 is blinking, then use a

smalleraperture to bring the required shutter speed down to what the camera is capable

ofdoing.

Theshutter speed also blinks as a shake warning if the shutter speed falls more than

1/2stop belowthe reciprocal of the lens length.

Mis for manual exposure mode. You select the aperture with the Main Dial and

shutter speed with the QCD. The camera’s built-in light meter will still function in

manualmode andyou can follow its lead or ignore it completely. The meter’sdisplay

can be seen both in the viewﬁnderas well as on the top mounted Liquid Crystal Dis-

play (LCD) on the top right side of thecamera. A proper exposure, according to the

camera’smeter, is when the meter indicator is centered on the scale. The meter scale

covers a four stop range. Each hash mark represents 1/2 stop of exposure deviation.

A negativeindication shows with underexposure and a positive indication shows with

overexposure.

DEP is for depth of ﬁeld auto exposure mode. Itallows the camera todecide the

appropriate aperture andfocus position to provide enough depth of ﬁeld to keep two

selected distances sharply in focus. The easiest way to use it is to turn the Command

Dial to DEP,and use the center auto focus sensor, point the camera at the ﬁrst subject

andpress the shutter button half way to autofocus. Let the button up and then point the

same AF sensor on the top of the second subject and press the shutter half way again

to allow the lens to autofocus onthe second subject. Then reframe your camera and

takethe picture. Thecamera will select a focus distance between the subject distances,

then select an aperture small enough to keep both subjects in focus and then select a

shutterspeed that willprovideproper exposure. Ifyou select the same subject distance

twice, the camera will select the widest apertureavailable to keep depth of ﬁeld very

shallow.The lens must be set to AF for DEP mode to work and if you are using a zoom

lens, you must not change its zoom setting during the entire procedure. Youcan also

manuallyor eye controlselect the side AF sensors, but I think it justadds confusion.

Ablinking aperture indicated that sufﬁcient depth of ﬁeld (DOF) can not beachieved.

Youmust focus on subjects that are closer to the same distance apart or use a wider an-

glelens. Flashcan not be used with DEP mode

CF (CustomFunction) is discussedbelow

CAL (Elan IIe only) is used for calibrating the Eye Control Focus (ECF) of the

Elan IIe to the shape and size of your eye. Turn the Command Dial to CAL, look

directly at the blinking AF point, press and hold the shutter button until the camera

beeps. Thenlook directly at the next blinkingAF point and hold the shutter button

until the camera beeps. Turn the camera to the vertical position and press and release

the shutter brieﬂy. Then look directly at the blinking AF point, press and hold the

shutterbutton until the camera beeps. Thenlook directly at the next blinking AF point
