35

BASIC OPERATION [SHOOTING]

Using the Multi (6)Segment MeteringMode
In the Multi (6)-Segment
Metering Mode, the meteringsystem automaticallymeasures light in six
different zones, enablingproper exposure value in awide variety of normal andadverse lighting conditions.

● The Center-Weighted Metering
Mode and Spot Metering Modeare also available in thiscamera. See page 55 and 56
for more details.
● When the lens is stopped
down, the exposure
metering mode is set toCenter-Weighted Metering
Mode even if the meteringmode selector is set to Multi(6)-Segment Metering Mode.

36

Set the metering mode selector
to K.

L is displayed in the viewfinder.

BASIC OPERATION [SHOOTING]

Multi (6)-Segment Metering
This camera incorporates a highprecision six-segment TTL
metering system. Light values
are measured in six segments
within the image field, enablingan optimal exposure to be madeunder a variety of lighting
conditions. With conventional
averaged metering systems, underexposure of the subject results fromthe brightness of the background affecting the overall metering. With
multi (6)-segment metering, the camera records the brightness in six
zones within the image field and uses these measurements to choose
an exposure that will not underexpose the subject. The multi (6)segment metering system also calculates exposure values for a scene
to automatically compensate for high-contrast and other difficult
lighting conditions. Even a beginner can achieve excellent results with
ease.

37

BASIC OPERATION [SHOOTING]

Holding the Camera● To reduce the camera
shake, support your bodyor the camera on a solid
object- a table, tree, or awall for instance.
● When using an ultratelephoto lens, a tripod thatis heavier than the total
weight of the camera andlens is recommended to
avoid the camera shake.

Camera held horizontally

Camera held vertically

For best results, be sure to
hold the camera correctly as
shown in the illustrations.
Hold the camera firmly, with yourleft hand supporting the camera
and lens as shown in theillustrations. While taking a
picture, hold your breath andgently depress the shutter
release button. (Sudden force on
the shutter release button willcause camera shake, making thepicture blurred.)

Although there are individual differences among
photographers, in general the shutter speed for a hand heldcamera is the inverse of the focal length.
For example, 1/75 of a second when the focal length is 75
mm, and 1/150 of a second when it is 150 mm. A tripod
should be used for shutter speeds slower than this.
When the tripod is used, use of an optional Cable Release isrecommended.

detached is squeezed too tightly, it may be difficult todetach the ring. In this case, hold down and rotate theframe of the eyepiece using the back side of the strap(the side without the word PENTAX on it) to make iteasier to detach the ring.
● When using an ordinary polarizing filter, exposure
accuracy can be adversely effected. The use of a circularpolarizing filter is necessary for proper exposure.
● If you are using the auto close-up ring in the AperturePriority AE Mode, make sure to narrow the aperture
before taking a picture. Otherwise, the exposure will notmatch.

● The autobellows without the extension tube (Outerbayonet No.1) cannot be attached to the 672 camera if
the AE Pentaprism 672 is used. The extension tube
(Outer bayonet No.1) and the scale (Scale 672) areavailable as an optional accessory.

Rear Converter● When the Rear Converter is used with the focusing
screen for telephoto lens installed (BA-81, BB-81, BE-80,
BG-80, BH-81 or BJ-81), a slight amount of overexposure
will occur.

ADVANCED OPERATION

Aperture and Shutter Speed Effects
Deciding the appropriate exposure for an object that you want to photograph (the subject) is all about deciding the rightcombination of shutter speed and aperture value. However, even for subjects with the same brightness, there are several
combinations of shutter speed and aperture value possible. Depending on which combination you select, the effects of thepicture differ.

The Effect of Shutter Speed
The shutter speed adjusts the amount of light that is exposed to the film by lengthening or shortening the length of time thefilm is exposed to the light.
If the shutter speed is slow, the shutter is open for a long amount of time, and if the subject that you want to photograph at thistime is moving, the subject will naturally become blurred. On the other hand, if the shutter speed is fast, even if the subject ismoving, the camera is able to take a picture as though the subject is stationary. Setting a fast shutter speed can also prevent
pictures from blurring due to the camera shaking when you press the shutter. Also, if you take pictures of rivers, waterfalls,
waves, etc., at a low shutter speed, they will turn out as pictures with a motion-like quality.
Fast Shutter Speed

Slow Shutter Speed

ADVANCED OPERATIONThe Effect of Aperture
Aperture refers to adjusting the amount of light that hits the film, by widening or narrowing the beam, or “thickness” of lightthat passes through the lens.
If the aperture is opened, thus widening the beam of light, the objects in front of and behind the subject in focus are blurred.
In other words, the focus range becomes smaller. On the other hand, by narrowing the aperture and thus narrowing the beamof light, the focus range becomes larger.
For example, when taking a picture of a subject against a background, if you widen the aperture and you take a picture, theareas other than the subject focused on become blurrier, making the subject appear to be in the foreground. On the other
hand, by narrowing the aperture, it is possible to keep the background areas in focus.

Custom Function
The Pentax 672 offers “Custom Functions” to modify the camera’s operation to suit personal
preferences. Modifications are made at a Pentax service center (at some charge).
Please consult your local Pentax service center for details.
(1) 1/2 EV Shutter-speed settings

Shutter speeds can be divided into 1/2 EV steps.
(2) Metering timer duration

The 10-second metering timer can be changed to 5, 20 or 30 seconds. In memory lock mode, thetimer is changed from initial 20 seconds to 10, 40, or 60 seconds.
(3) F-number indication in viewfinder display

The selected aperture is displayed in the viewfinder LCD indicator instead of exposure frame
number. This Custom Function is available only when a lens with automatic diagram control ismounted.
(4) Installment of an additional strap lug

An additional strap lug is installed next to the grip for horizontal positioning of the camera.
Precautions Regarding Custom Functions● For modification (3), if f-stops are displayed in the viewfinder, then the film number is not displayed.
● For (3), the f-stop is not displayed if the lens or accessories do not support photometry.
● For (3), the f-stop displayed in the viewfinder does not necessarily match with the aperture set with the lens.

Error Display in the Event of Incorrect Operation
In the event of unusual operation of the camera, [E] followed by double figures, e.g. [E-13], willappear on the LCD panel to indicate an error. When this happens, the shutter cannot be released. In
this event, follow the instructions below.
If the first figure after [E] is“1” or “3”This indicates camera breakdown, irrespective of the second figure. You should take thecamera to your local Pentax service center.

If the second figure after [E]is “1”, “2” or “3”If there is a film in the camera, wind to the end and remove the film. Press the shutter and if
the error display disappears, the camera is ready for use. We recommend, however, thatyou have the camera checked at your local Pentax service center. If there is no film in thecamera, open and close the back cover. If the error display disappears, the camera is
ready for use.

If [PErr] is displayed

Take the viewfinder out and put it back two or three times. If the error display disappears,
the camera is ready for use.

In rare cases, the camera may not operate correctly due to static electricity. This can be remedied by taking the batteries
out and putting them back again.
