Advanced Photography and Various Functions This chapter describes various functions of the camera.
Focus Area Focus Modes Single focus mode (S) Focus Area This mode uses the focus-priority mechanism. The shutter can be released when the focus mark in the viewfinder is lit. This mode is suited for still subjects. Focus is locked when the focus mark lights in the viewfinder’s LCD. With this camera, you can select the focus area that best suits the kind of pictures you intend to take. The selected focus area can be checked on the external LCD panel.

Switch to “M” (manual focus mode). 2. Manual focus operation for telephoto and zoom lenses.
Attaching a Leaf Shutter Lens Manual Focus Mode (continued) Leaf shutter lenses are equipped with an internal shutter. When set on X, leaf shutter lenses charge quickly and are capable of high shutter speeds (1/800 sec.) with flash synchronization during daytime shooting. By merely pressing the shutter button, the leaf shutter will automatically charge, allowing for rapid photography.
When Auto Focus Fails Using the Focus Lock Function The Auto Focus function requires contrast on the subject. Auto Focusing may fail to achieve accurate focus with certain subjects described below. In such cases, either switch to the manual focus mode and focus manually, or bring into focus an object at the same distance as the object you want to photograph, lock the focus using the focus lock mechanism, then take the picture.
AF Assist Infrared Light 22 L 11 22 11 4 4 C S 5 f mt P M.U When the subject is dark or under-exposed and the camera fails to auto-focus, a red lamp may light on the front of the camera when the shutter release button is half-pressed. This is a light that assists the camera’s auto focus function. Drive Modes Single-Frame Mode The film is advanced by one frame each time the shutter is released. Set the shutter release mode selector lever to “S”. P M.
Exposure Modes Drive Modes (continued) Program AE (P) Self Timer Mode ( ) In this mode, the shutter will be released after the set time once the shutter button has been pressed. The aperture and shutter speed are determined automatically for the optimum exposure, according to the existing ambient light. This mode is best suited for general photography, allowing the user freedom to concentrate on the subject. For instructions about the self timer function, see page 66.
Exposure Modes (continued) 8 9 10 11 12 13 14 Aperture Priority AE (Av) (ISO 100/AF80mm f/2.8 D) 15 16 17 18 19 20 21 22 EV Set the desired aperture, and the camera selects the optimum shutter speed accordingly.

Turn the exposure mode setting dial to “Av” (aperture priority AE) position.
Exposure Modes (continued) Shutter Priority AE (Tv) Manual Mode (M) Set the desired shutter speed and the camera selects the optimum aperture accordingly. Fast shutter speed can be used to freeze motion, and slow shutter speed can be used to blur motion on purpose. This mode is used to set both the aperture and shutter speed for total exposure control. Varying shutter speeds can be selected, including “bulb”, “tIME” and manually from 60 mins to 1/4000 sec.
Exposure Modes (continued) 4. When the shutter release button is halfpressed, the difference between the present settings and the metered value is displayed in the viewfinder’s LCD panel. The value is displayed in 1/3 stop increments within a range of 6 EV.
Exposure Modes (continued) X C1 C2 Av M C3 CF X M C3 P C1 When using the leaf shutter lens, the leaf shutter's working range is from 1/800 sec. to 1 sec. For other speeds (1/4000-1/800 sec., 1-60sec., bulb) use the focal plane shutter. Tv Tv Av Synchro mode (X) P CF Auto mode mechanism Select this mode when you use a flash. The shutter speed will be fixed at 1/125 second for synchronization. To adjust synchro speed, turn the rear dial.
Exposure Metering Modes Exposure Modes (continued) There are three exposure metering mode to select a proper exposure modes appropriate to the lighting condition of subject.

B 4 * The illustration shows the exposure mode “Av” (aperture priority AE) being recorded to C2.
Exposure Compensation warnings When a polarizing filter is used, ensure that a circular polarizing filter (circular filter: C-PL) is used. The correct exposure cannot be obtained with a normal polarizing filter (PL). In some situations, such as a great difference between the subject and background brightness or overall subject tones that will not meter correctly because they are all black or white, the resulting photograph may be under- or overexposed.
AE Lock Mode Shooting with the AE lock function is useful in cases where the desired focal point differs from where the focal point is usually measured, or when it is necessary to measure the exposure using spot metering in order to bring the desired subject into focus. The AEL button will lock the Auto-exposure value as the photo is being recomposed. X M CF 1. Turn the exposure mode setting dial and select “P”, “Av” or “T”.
Auto Bracketing Mode X CF M X CF M P C1 Tv Av P C1 C2 A C2 C3 Tv Av 1. Turn the shutter release mode selector lever to the “S” or “C” position. When set at the “S” position, you can shoot one frame with each press of the shutter release button.
