*Flash strength

The flash on the IS-1 uses a new exposure control system. This flash system combines advantages

of both "flashmatic", employed in compact cameras and "auto flash" which is employed in SLRs. Flashmatic emits full - strength flash while the camera automatically adjusts the aperture level for proper exposure. In most cases this is an effective system. However, when the subject is at extremely close range, subjects tend to be over exposed, and the background too dark because the aperture has been adjusted to its most narrow setting. On the other hand, auto flash controls the amount light emitted by the flash. This system decides exposure by measuring reflected light. But, depending on the background, exposure for the main subject can be affected. For example, with a white background, the subject may appear too dark due to the level of reflected light received through the lens. The reverse is true for a dark background.

The IS-1 employs a combination of aperture adjustment and flash strength to give you perfect exposure every time. That means that the effects of background lighting and distance-to-subject are both accounted for.

High Function Flash G40 (Optional)

The G40 is a dedicated flash for the IS-1 (GN131 ISO 100 • ft). It is designed for professional flash photo - effects such as bounce, multi-flash and Follow-synchro.

Bounce photography uses indirect lighting of subjects by reflecting flash light off of a ceiling or wall. With straight flash photography a strong shadow often appears behind the subject. By bouncing, you can obtain a soft, well-balanced lighting effect on the entire subject. You can also use the built-in flash together with the G40 for additional affect.

Multi-flash emits the light several times in one exposure. With this flash mode, continuous move- ment, such as a golf swing, can be photographed sequentially in one frame. It's a multiple exposure with flash.

With Follow-synchro mode, the flash fires at the final point of slow synchro. For example, the tail-lights of a moving automobile can be expressed.

When the IS-1 is equipped with the tele- converter lens (x 1.5) or the wide - converter lens (x 0.8), the built-in flash cannot be used. We recommend you to use the G40 for such cases.
