* The size of the increments for Fluorescent refl ects the wide variations in color tem per a-
ture among the many diff erent types of fl uorescent light source, ranging from low-tem-
per a ture sta di um lighting to high-temperature mer cu ry-vapor lamps.
Flash Range, Aperture, and Sensitivity
Flash range varies with sensitivity (ISO equivalency) and aperture.

In programmed auto, the maximum aperture (minimum f/-number) is lim it ed
ac cord ing to sen si tiv i ty (ISO equivalency), as shown below:
Maximum aperture at ISO equivalent of:
100 125 160 200 250 320 400 500 640 800 1000 1250 1600
2.8 3 3.2 3.3 3.5 3.8 4 4.2 4.5 4.8 5 5.3 5.6
For each one-step increase in sensitivity (e.g., from 200 to 400), aperture is
stopped down by half an f/-stop. If the maximum aperture of the lens is smaller
than given above, the maximum value for aperture will be the maximum aper-
ture of the lens.
