Fujifilm FinePix S5 Pro User Manual

78

This camera is equipped with a guide number 12 flash 
(ISO 100, m/ft) that can be used not only when natural 
lighting is inadequate, but also to fill in shadows and 
backlit subjects or to add a catch light to the subject’s 
eyes.

Speedlight emits series of nearly invisible preflashes 
(monitor preflashes) immediately before main flash. 
Preflashes reflected from objects in all areas of frame are 
picked up by 1,005-pixel RGB sensor and are analyzed in 
combination with information from matrix metering system 
to adjust flash output for natural balance between main 
subject and ambient background lighting. 
• If type G or D lens is used, distance information is 

included when calculating flash output. 

• Precision of calculation can be increased for non-CPU 

lenses by providing lens data (focal length and 
maximum aperture; 

➝p.121).

• Not available when spot metering is used. 

Flash output adjusted to bring lighting in frame to 
standard level; brightness of background is not taken into 
account. Recommended for shots in which main subject 
is emphasized at expense of background details, or when 
exposure compensation is used.
• Standard i-TTL flash for Digital SLR is activated 

automatically when spot metering is selected.

• i-TTL flash control can adjust for ISO sensitivities 

between 100 and 1600. It may not be able to adjust 
flash level appropriately for ISO sensitivities over 1600.

• The flash angle of the built-in flash can cover the field of 

view of an 18 mm lens. It may not be able to light the 
entire subject with some lenses or apertures.

• When [ON] is selected for [ISO AUTO CONTROL] 

under [ISO AUTO CONTROL] under [S EXPOSURE] 
in the [SET UP] menu, ISO sensitivity will automatically 
be adjusted as required for optimal flash output. This 
may result in foreground subjects being underexposed 
in flash photographs taken at slow shutter speeds, in 
daylight, or against a bright background. In these cases, 
choose a flash mode other than slow sync or select 
mode 

 or 

 and choose a larger aperture.
