FP High-Speed Sync Flash - Flash Photography At Higher Shutter Unlike other Nikon SLR models the F5, F90X/N90s or F90Series/N90 camera and the SB-26 allow you to use faster shutter speeds up to 1/4000 sec. for flash synchronization. Ordinarily the flash fires only when the curtains are fully opened in regular flash syncs. With FP High-Speed Sync Flash, the flash consecutively emits light at an extremely rapid cycle, while the shutter curtains travel to expose the entire film surface - but the curtains are never fully opened (i.e. exposure with a "slit"). By using a high-speed shutter and flash simultaneously, you can create light flow from a rapidly moving subject. In outdoor photography, it also enables you to use both a wider aperture and a faster shutter speed to achieve a shallower depth of field and purposely blur the subject's background. Note that a guide number for FP High-Speed Sync Flash varies with the selected shutter speed and it is smaller than for regular flash synchronization (i.e. smaller light output). Furthermore, we recommend you use shutter speeds between 1/250 and 1/4000 sec. to avoid uneven exposure. Before proceeding: E ATTACH SPEEDLIGHT TO CAMERA. E TURN ON BOTH SPEEDLIGHT AND CAMERA. E USE MANUAL EXPOSURE MODE. E USE SINGLE-SERVO AUTOFOCUS (S or A) OR MAN- UAL FOCUS (M). E USE SINGLE-FRAME SHOOTING (S) FILM ADVANCE MODE.

ISO speed of film in use is automatically set; if not shown in the LCD panel, lightly press the camera's shutter release button. 4 Confirm the zoom-head position has been set and appears in the SB-26's LCD panel. The zoom-head position is automatically set and indicated in the SB-26's LCD panel when the camera is used with an AF Nikkor lens (including the latest D-Type) or a Nikkor lens having a built-in CPU. Or, set manually according to the shooting situation (see page 29). DO NOT USE THE WIDE FLASH PANEL (zoom head at the 20mm or 18mm position). When used, m20 or m18, D and F blink in the LCD panel as an alert. 99
