3 Place your subject in the center of the autofocus frame. 4 Press the shutter release halfway to focus. A green light indicates the subject is in focus. (A red light indicates autofocus is not possible.) Over-exposure warning: blinks. 17 Under-exposure warning: blinks.
5 Press down on the shutter release. The film is automatically advanced one frame. In poor light conditions, the autofocus illuminator is automatically activated to determine the correct distance. However, there are some cases depending on the type of lenses used in which it cannot be used. Even in these conditions the subject distance can be determined when using the F280.
When battery power falls below 50 %, blinks after each shot, and charge time is increased when using the Power Flash Grip 300; therefore, changing the batteries is recommended.
Rewinding the Film Film rewind is also automatic. 1 Confirm that you have reached the end of the film. R blinks. 2 While sliding locking knob button .
On completion of rewind, the shutter is released, frame counter reads "0". 3 Open the camera back and remove the film. The film is completely rewound into the cartridge.
Taking Photographs II With a Continuous AF mode, and a Program Shift that lets you choose at any time to shift within the program in an aperture or shutter-preferred manner, the OM77AF provides for the expression of every photographic idea.
Taking a Continuous Series of Shots Continuous focusing and shooting is especially useful whan shooting moving subjects. As soon as the subject is in focus, the picture is taken and the film wound to the next frame. This process Is repeated as long as the shutter release is held down. Press the mode.

To Take Better Photographs The following pages are presented to assist those who wish to improve their photographic technique. Please read them carefully, apply the techniques and expand your creative horizons.
Autofocus (AF) TTL "Zero-In" System An exceptionally accurate TTL "Zero-In" electronic focusing system, which works on the princi- ple that image discrepancy is zero when an object is correctly focused, is employed by the OM77AF. Light passing through the focus-mirror is passed through an infrared cut filter, a correction lens and then projected onto a CCD "Zero-In" sensor where it is converted into electrical signals.
Subject difficult for autofocus Although the OM77AF can focus in almost any situation, there are certain conditions, illustrated below, in which it may be impossible to obtain correct focus. A red LED in the viewfinder will usually indicate these conditions, however, in situations , and , the green LED in the viewfinder may illuminate even though the lens is incorrectly focused.
Program The OM77AF programs offer the optimum balance aperture at any time and employ the program as an between aperture and shutter-speed settings to enable quick response to every photographic opportunity. Also, the Auto Program Shift selects automatically a program appropriate to the present focal length of the mounted lens, while the Manual Program Shift lets the user shift shutter speed and aperture or shutter speed-preferred auto-exposure program.
Auto Program Shift The OM77AF has been programmed to automatically select a program mode appropriate to the focal length of the lens to be used. There are individual programs for telephoto, standard and wide angle lenses, with the capacity to automatically shift programs in line with the focal length changes of zoom lenses. In the wide-angle program mode (Program chart ), for lenses below 35 mm, depth of field is given priority.
Manual Program Shift With the OM77AF, the photographer is free to select a desired aperture or shutter speed with the assurance of a perfect exposure. For instance, when using a 50 mm F1.8 AF lens, the initial setting of aperture and shutter speed is in accordance with the Standard Program (Program chart ). By using the shift-knob, the photographer is free to shift the program line by 1/2-stops to reach a desired shutter speed or aperture.
Power Flash Grip 300 By using the Power Flash Grip 300, you are always ready for problem-free flash photography. With the flash reflector up, the unit will fire automatically at 1/100 sec. in this case, and the aperture determined by the AF CPU on the basis of the absolute distance of the subject (Flashmatic method), as only when natural light requires a shutter speed of illustrated by the dotted line in the chart. 1/100 sec. or slower.
Full-Synchro Flash F280 Combined with the F280, the OM77AF can synchronize with the flash unit at all shutter speeds, resulting in a flexible program that can cope with fill-in flash photography as easily as it can mum aperture of the lens), and when natural light requires a speed of 1/100 sec. or slower a Normal "OTF" Flash is produced; when a higher speed is required, a Super FP Flash is produced auto- the more usual poor light situation.
T-Series Flash Combined with a T-Series flash (except the T-45), the OM77AF can be used for a variety of advanced flash techniques, bounce or diffused lighting for example, while correct exposure is assured by the camera's TTL Direct "OTF" program, which controls the amount of light emitted in accordance with the distance of the subject. When using a T-Series Flash, the aperture is set at f4, the shutter speed is set at 1/100 sec., and a flash fired only when a shutter speed of 1/100 sec.
TTL Direct "OTF" Light Metering (Center-weighted, Averaged Light Metering) 63 The OM77AF employs the famous TTL Direct "OTF" (Off-The-Film) light metering system. An tions beforehand, as is the case in macro photography.

LCD Panel The OM77AF employs a large interactive LCD panel that can "reply" to the photographers adjustments with information on the camera's operating condition.
OM Lenses While designed for a new series of Olympus AF lenses, the OM77AF can be used with non-AF OM lenses (although not in the AF mode), with the result that most Zuiko lenses, from the Fisheye to the tele-converters, can be mounted on the camera. The camera will automatically select the aperturepreferred AUTO mode and a shutter speed appropriate for the aperture selected by the photographer.
