Using the shooting functions
You can keep the image from becoming overexposed or underexposed when shooting a high-
keyed or low-keyed subject.
This function is also available for a RAW file.
1 Display the ISO/Zone Matching screen with the function dial and the Fn button (page 43).
2 Select [Lo80] or [Hi200] with v/V/b/B on the controller, then press the center of the controller.
• [AUTO], [100], [200], [400], [800] and [1600] options are used for ISO sensitivity (page 44).
The ISO sensitivity is set to the equivalent of ISO 80 in [Lo80], and of ISO 200 in [Hi200].
When zone matching is used, the contrast setting in the color mode is deactivated.
Refer to the following table to determine the flash range.
Zone Matching
Lo80
This keeps the image from becoming underexposed. Use in
low-key (predominantly dark) scenes is recommended, as the
image tends to become whitish.
Hi200
This keeps the image from becoming overexposed. Use in
high-key (predominantly light) scenes is recommended, as
the image tends to have heightened noise level.
