Self-Timer Mode
The self-timer mode delays the shutter release, andis useful for taking group shots that include the photographer. The shutter will be released about 12
seconds after the shutter release button is pressed.

• The shutter will be released about 12 seconds
later.
• When the Self-Timer is in operation. The audible
PCV signal is heard and the rate increases for thelast two seconds.
• To cancel the Self-Timer operation after it has been
activated, move the drive mode selector to a position other than r or set the main switch to the
OFF position.
• The Self-Timer delay time can be set to 12 sec. or
2 sec. (with mirror lock-up) with Pentax Function

About Exposure Compensation

ADVANCED OPERATIONS

1

2

PurposeThe exposure compensation allows you to deliberately
overexpose (brighten) or underexpose (darken) a subject,or to compensate for difficult lighting conditions which
may fool the camera's built-in exposure meter.

• Exposure compensation does not work in the Bulb
Exposure Mode.
• The exposure compensation range is -3 1/3EV to +3 1/
3EV in 0.3EV step.
• The exposure compensation step can be selected from
0.3EV step to 0.5EV step with Pentax Function No.5.
See page 79 for more details• When the 0.5EV step is selected, two bars above thebar graph indicate a 0.5EV step.
• When exposure compensation is used in the Metered
Manual mode, the bar above the bar graph indicates
under or overexposure, it is not indicating the exposurecompensation value. w is displayed.

To set1. Turn the exposure compensation dial to thedesired compensation value.
2. The exposure compensation dial locks at the a position. To

• Three pictures are taken consecutively as follows.
First picture:
Correct exposure
Second picture: Underexposure
Third picture: Overexposure• The sequence of the auto bracketing exposures can bechanged with Pentax Function No.3.

• The camera automatically measures the exposure foreach shot.
• The focus is locked at the first picture and remains
locked until all pictures are taken.
• If you let go of the shutter release button during auto

Switching the Metering Mode

Using the Center-Weighted Metering Mode
This metering system does not automatically compensate for backlit or spotlit scenes like theMulti(6)Segment Metering Mode. Creative exposure control is decided by the user.
To set
Set the metering mode selector to the J position.

• The metering pattern in the illustration aboveshows that the upper part of the pattern (in thecenter of the viewfinder) has more sensitivity tolight than the lower part.
• In this metering mode, the camera does not automatically compensate the exposure in backlit or

The Spot Metering Mode measures light only in thesmall area in the center of the viewfinder.
To set
1. Set the metering mode selector to I.

2. Measure the small area of the viewfinder as
illustrated.
• If brightness is much different between the centerand the other area of the photograph, exposure
should be determined in consideration of the overall brightness. Otherwise, the picture will come out
improperly exposed.

Using AE Lock

57

The AE lock function memorizes an exposure before
shooting. The AE lock function is very effective whenused along with the spot metering. Use the AE lockfunction to get a correct exposure when the subject
occupies only a small part of the viewfinder.
Position the area to be measured in the spot
metering area and press the AE lock button.
The exposure level is memorized and n is displayed in the viewfinder.

How to cancel
To cancel the AE lock function, press the AE lockbutton again.

ADVANCED OPERATIONS• As soon as the AE lock button W is pressed,
and the camera stores the measured exposurelevel for 20 seconds. The AE lock function
remains while the AE lock button is pressed.
• If the shutter release button is pressed halfway
down while the AE lock timer is operating, thememorized meter reading will remain even if the
AE lock button is released.
• The AE lock function cannot be used when thecamera is set in the Metered Manual Mode.

Setting the Focus Mode Switch to the Continuous Position
Predictive Autofocus Mode
When the camera senses subject movement during
the autofocus operation, the camera will automatically switch the focus mode to the predictive autofocus mode to measure the speed of a moving
subject, and predict where it will be at the momentof shutter release to maintain sharp focus on thesubject. If the subject is moving too fast, the shutter
may not be released.

HARD-TO-AUTOFOCUS SUBJECTSThe autofocus system is highly precise, but not perfect. Depending on the brightness, contrast, shape,and size of your subject, the autofocus system may
not operate. In such a case, use the focus-lock
technique (see page 60) on another subject that is
the same distance away, or set the lens to use themanual focus mode to focus the lens on the subject
with the aid of the matte field in the viewfinder.

How to focus on the subject with the aid of thematte field

2. While looking through the viewfinder, turnthe focusing ting to the right or left until theimage in the viewfinder is clearest.

a) Extremely low-contrast subjects such as a whitewall in the autofocus frame l.
b) Subjects which don't reflect much light in theautofocus frame l.

Daylight- Sync Shooting
PurposeWhen taking a portrait in daylight, the subject's face
may be covered by shadow. The use of a flash will
help eliminate the unwanted shadow.
Daylight-sync photography is accomplished in
the same manner as normal flash photography,
so you simply press the shutter release but-ton.

ADVANCED OPERATIONS

Without Daylight-sync

With Daylight-sync• lf the background is too bright, it may be overexposed.

Slow-Speed-Sync Shooting
PurposeIt is possible to balance the exposure of a foreground subject against a dimly lit background byusing the flash to properly expose the foregroundsubject and a slow-shutter-speed to expose the low
light background.

To setWith the Shutter-Priority AE Mode set
1. Set the camera's exposure mode to the Shutter-Priority AE Mode.
2. Set the desired shutter speed.
• lf the aperture in the viewfinder blinks, a correct
exposure will not be obtained for the background.
Adjust the shutter speed until the blinking stops.
3. Turn the flash on.
4. Take the picture.
• lf the power is on before the desired shutter
speed is selected, the proper exposure for the
back-ground will not be obtained. Be sure toselect the shutter speed before the flash is turnedon.
• ln the slow-speed-sync shooting, use of a tripod isrecommended to prevent camera shake.

ADVANCED OPERATIONSTo setWith the Metered Manual Mode set

Notes on Accessories
When using an ordinary polarizing filter, a half mirror incorporated into the autofocus system reduces
the effectiveness of the autofocus function whenused in combination with an ordinary polarizing filter. Use a circular polarizing filter for proper autofocus operation.
