3. Using Special Features With a Type-A camera, Speedlite 38OEX enables FP flash and FE lock. (1) FP flash FP (focal-plane) flash, or high-speed sync, enables the Speedlite to synchronize with a shutter speed faster than the camera's maximum sync speed. When a sync speed faster than the camera's maximum sync speed is set, Speedlite 38OEX automatically sets the high-speed sync mode for auto flash exposure. FP flash can be used in the P, Tv, Av, M, and DEP modes. It is effective when you want to use fill flash for an outdoor portrait while blurring the background with a large aperture. It can also be used to produce a catchlight in the subject's eyes or to eliminate harsh shadows. The result is best with a fast (large-aperture) lens. • If a large aperture is to be used, set the camera to the Tv, Av, or M mode. EP Av Ty 000 O, r I F.
