Shooting Situation
(No flash)
Flash Range
100 - 200 Sunny outdoors
The higher the ISO speed,
the farther the flash range
will be (p.62).
400 - 800 Overcast skies, evening
1600 - 6400, H Dark indoors or night
In the [7 Custom Functions (C.Fn)] menu, if [Highlight tone priority]
is set to [1: Enable], ISO 100, ISO 6400 and “H” (equivalent to ISO
12800) settings cannot be set (p.186).
Using a high ISO speed or shooting in high-temperature conditions may
result in more grainy images. Long exposures can also cause irregular
colors in the image.
When you shoot at high ISO speeds, noise (horizontal banding, light
dots, etc.) may appear.
Under the [7 Custom Functions (C.Fn)] menu, if [ISO expansion] is set
to [1: On], ISO 6400 and “H” (ISO 12800) can also be set (p.184).
