BASIC OPERATION (SHOOTING)
II. BASIC OPERATION (SHOOTING)
Using the Programmed AE Mode
Purpose For easy picture taking, use this mode. In the Programmed AE mode, the camera automatically selects the best combination of aperture and shutter speed settings allowing you to take pictures by simply pressing the shutter release button. To set 1. Turn the lens aperture ring to the b position as shown in the illustration. To move the lens aperture ring to the b position, turn the aperture ring while holding down the aperture-A lock button on the lens. The lens aperture ring can be released from the b position in the same manner.
2. Turn the shutter speed dial to b while holding down the shutter speed dial release button. The shutter speed dial can be released from b in the same manner. You can shift the program line of Programmed AE Mode with Pentax Function No.6. See page 80 for more details. See page 44, 46, 48, and 50 for other available exposure modes.
Using the Multi(6)-Segment Metering Mode
In the multi(6)-segment metering mode, the metering system automatically measures light in six different zones, enabling proper exposure in a wide variety of normal and adverse lighting conditions. Set the metering mode switch to L. The center-weighted metering mode and spot metering mode are also available in this camera. See page 55 and 56 for more details. When the Adapter 645 for 67 lens or Helicoid Extension Tube 645 attached, the center-weighted metering mode is automatically set even if you select the multi-segment metering mode. The multisegment mode cannot be used.
MULTI(6)-SEGMENT METERING This camera incorporates a high-precision six-segment TTL metering system. Light values are measured in six segments within the image field, enabling an optimal exposure to be made under a variety of lighting conditions. With conventional averaged metering systems, underexposure of the subject results from the 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.

Using Autofocus Mode

Switching between the autofocus mode and manual focus mode depends on the lens you use. For more details, read the operating manual of the lens. The camera does not provide the switch for switching between the autofocus mode and manual mode.

3. Set the desired f-stop. 4. The f-stop that you have selected and appropriate aperture indication determined by the camera can be seen in the viewfinder when the shutter release button is pressed halfway. The approximate aperture indication appears in the viewfinder. It may not the same indication as that you selected with the lens aperture ring especially when the A645 150mm f/3.5 or A 645 4582mm Zoom f/4.5 is attached.
* Exposure Warning If the subject is too bright or too dark, the selected shutter speed will blink in the viewfinder and on the LCD panel as a warning as shown. When the subject is too bright, choose a smaller aperture, if available; when it is too dark, choose a larger aperture, if available. When the shutter speed indication stops blinking, you can take the picture. If both shutter and aperture blink, it means that the exposure is out of metering range and unable to obtain a correct exposure even if the aperture is adjusted. Select a darker subject if it is too bright, or use a flash if it is too dark.
Using the Shutter-Priority AE Mode Purpose When the desired shutter is selected, the appropriate aperture is automatically set by the camera for a proper exposure according to the brightness of the subject. This mode is suitable for freezing the action with a fast shutter speed or capturing a flowing dynamic image with a slow shutter speed.
To set 1. Set the lens aperture ring to b. 2. Set the shutter speed dial to a shutter speed other than b. To set the shutter speed dial to a position other than b, turn the shutter speed dial while holding down the shutter speed dial lock button. 3. Set the shutter speed dial to the desired shutter speed.
4. The shutter speed dial between 1/1000 to 4S can be set to 1/2 step by pressing the up/down button. The set shutter speed will be displayed on the LCD panel and in the viewfinder. If the shutter speed does not change to 1/2 step, confirm Pentax Function No. 1 When the shutter release button is pressed halfway down, the shutter speed and the aperture value will be displayed in the viewfinder. In flash photography, when you use flash sync shutter speed of 1/60 second or a non-dedicated external flash unit, set the shutter speed dial to the e (1/60 of second ) position.
* Exposure Warning If the subject is too bright or too dark, the shutter speed and aperture setting in the viewfinder blink. When the subject is too bright, choose a faster shutter speed. When the shutter speed indication stops blinking, you can take the picture. If both selected shutter speed and aperture blink, it means that the exposure is out of metering range and unable to obtain a correct exposure even if the shutter speed is adjusted. Select a darker subject if the subject is too bright. Use a flash if it is too dark.

Using the Metered Manual Mode Purpose The Metered Manual Mode is a convenient exposure mode for taking pictures using the same shutter speed and aperture setting combination, or taking creatively under or over exposured photographs. To set 1. Set the lens aperture ring to the desired fstop setting. Turn the lens aperture ring while holding down the aperture-A lock button.
2. Set the shutter speed dial to the desired shutter speed. 3. The shutter speed dial between 1/1000 to 4S can be set to 1/2 step by pressing the up/down button. The set shutter speed will be displayed on the LCD panel and in the viewfinder. If the shutter speed does not change to 1/2 step, confirm Pentax Function No. 1 To set the shutter speed dial to a position other than b, turn the shutter speed dial while holding down the shutter speed dial lock button. When the 645 LS (with leaf shutter) 75mm is attached, C Appears on the LCD panel.
4. Turn either the shutter dial or lens aperture ring until a single bar is displayed in the center of the bar graph. 5. When the shutter release button is pressed halfway, the shutter speed, approximate aperture and bar graph will be displayed in the viewfinder. When the bars are displayed to the j side on the bar graph, it indicates overexposure and when the bars are displayed to the o side, it indicates underexposure. Moving one bar on the bar graph indicates 1/3 step (EV). However, when under or over exposure is set beyond + 3 or - 3 steps (3EV), j or o indicator will blink.
In flash photography, when you use the flash sync shutter speed of 1/60 second or a non-dedicated external flash unit, set the shutter dial to the e (1/60 of second) position. * Exposure Warning If the subject is too bright or too dark, the selected shutter speed will blink in the viewfinder as a warning as shown. When the subject is too bright, choose a smaller aperture; when it is too dark, choose a larger aperture. When the shutter speed indication stops blinding, you can take a picture. If both shutter and aperture blink, It means that the exposure is out of metering range and unable to obtain a correct exposure even if the aperture is adjusted. Select a darker subject or use a flash if it is too dark.
Using the Bulb Exposure Mode Purpose This mode is useful for the long exposures required for shooting night scenes and fireworks. The shutter remains open as long as the shutter release button is held down. To set 1. Set the lens aperture ring to the desired fstop other than b while holding down the aperture-A lock button.

4. Adjust the desired aperture by lens aperture ring.
When using this mode, use a steady tripod to prevent camera shake and attach the optional "Cable Switch CS-105 CS-130" or Release Timer Switch TS-110 after removing the Release Socket Cap. Up to approx. 8 hours exposure is possible with new alkaline batteries at room temperatures.
About Exposure Compensation
Purpose The 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. To set 1. Turn the exposure compensation dial to the desired compensation value. 2. The exposure compensation dial locks at the a position. To set the exposure compensation dial to a position other than the a position, turn the exposure compensation dial while holding down the exposure compensation dial while holding down the exposure compensation dial release button. 3. The bar graph indicates the compensation value and w appear in the viewfinder.
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 the bar 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 exposure compensation value. w is displayed.
Auto Bracketing Exposure Mode
When you take a picture that requires exposure compensation and it may be difficult to determine the correct exposure, use this mode to make three different bracketing exposures with different exposure levels. Selection of auto bracketing amount. The auto bracketing amount can be selected from 1/3EV step or 1/2EV step.
To set 1. While holding the auto bracketing selector at the STEP position, press the up/down button to select the desired auto bracketing amount. The bracketing amount can be set to 13 (1/3EV step) or 12 (1/2EV step). 2. Release the finger from the auto-bracketing selector. The selector returns to the 0 position to complete the set-bracketing amount.

Metering area Using the Spot Metering Mode The Spot Metering Mode measures light only in the small 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 center and 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

As soon as the AE lock button W is pressed, and the camera stores the measured exposure level 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, the memorized meter reading will remain even if the AE lock button is released. The AE lock function cannot be used when the camera is set in the Metered Manual Mode. The AE lock function memorizes an exposure before shooting. The AE lock function is very effective when used along with the spot metering. Use the AE lock function 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 lock button again.
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 moment of shutter release to maintain sharp focus on the subject. If the subject is moving too fast, the shutter may not be released.
If the shutter release button is held at the halfway position, the lens focuses continuously to follow the subject. The shutter can be released even if the subject is out of focus. Set the focus mode switch to h.

Using the Spot AF Mode

AF area
Select the Spot AF Mode to critically focus on a specific spot of the subject which is in the spot AF autofocus frame. How to focus 1. Set the AF frame selector to 5.
2. Focus on the main subject with the Spot AF frame. When the main subject is off the Spot AF frame, use the focus-lock technique. See page 60.

Focus Lock Function

In the Spot Metering Mode, the camera focuses with the spot metering / focusing area of the viewfinder. If you shoot without positioning the spot metering / focusing area on the main subject, the main subject will not be focused properly. Set the AF frame selector to 5. 1. When the composition does not allow the autofocus frame to be placed over the most important subject, the camera will focus on the background as shown in the illustration. The focus lock can be used in the 3-point AF Mode and Spot AF Mode. The focus lock does not operate when the AF mode selector is at h.

Using the TTL Auto Flash 1. Remove the hot shoe cover and attach a Pentax dedicated flash unit. 2. Turn the flash ON. 3. Set the flash to TTL Auto mode. 4. Confirm that the flash is fully charged. 5. Focus on the subject and release the shutter. Auto Bracketing Exposure mode with a Pentax TTL dedicated flash When the auto bracketing exposure mode is selected with a Pentax dedicated TTL flash in use, only the amount of flash output is varied.
AF500FTZ, AF330FTZ and AF360FGZ These flash units feature a built-in infrared spotbeam to assist the autofocus system in dim light and low-contrast conditions. The auto zoom function will automatically adjust the angle of discharge according to the lens focal length only when a 645 FA lens is in use. The AF500FTZ and AF360FGZ feature a wireless slave synch flash function. The flash effective range appears on the LCD panel only when an a 645 A- lens is in use, or FA lens is in use. Multiple flash burst on a single frame is possible with the AF500FTZ. In the Programmed AE, Shutter-Priority AE, or Aperture-Priority AE, the TTL Auto Flash Mode will be set automatically even if the flash is set to Manual. With AF360FGZ, the picture format size can be selected depending on the camera format being used. AF240FT, AF400FTZ These flash units feature a built-in infrared spotbeam to assist the autofocus system in dim light and low-contrast conditions. In the Programmed AE, Shutter-Priority AE, or Aperture-Priority AE: TTL Auto Flash Mode will be set automatically even if the flash unit is set to Manual. When the flash unit is charged and left unused for about 5 minutes, the power will automatically be turned off to save battery power. Pressing the shutter release button halfway down will restart charging of the flash unit. AF200T, AF220T, AF280T, and AF400T If the TTL auto mode is selected, these flash units can be used for daylight-sync shooting, because the shutter speed is adjusted according to the ambient brightness. The slower shutter speed varies according to the lens focal length. The shutter speed varies between 1/60 second and a lower speed which does not cause camera shake. However, when a 645 A-lens is in use, the shutter speed is set to 1/60 second. The aperture value will also be fixed but will vary depending on the ISO of the film being used.
