Troubleshooting Guide

ISO 100 cannot be set.

Under [53: Custom Functions (C.Fn)], if [6: Highlight tone priority]

is set to [1: Enable], ISO 100 cannot be set. If [0: Disable] is set, ISO 100 can be set (p.261). This also applies to movie shooting (p.173).

ISO speed [H] (equivalent to ISO 12800) cannot be set.

Under [53: Custom Functions (C.Fn)], if [6: Highlight tone priority]

is set to [1: Enable], the [H] ISO speed (equivalent to ISO 12800)

cannot be selected even when [2: ISO expansion] is set to [1: On]. If

[6: Highlight tone priority] is set to [0: Disable], [H] can be set (p.261).

The Auto Lighting Optimizer cannot be set.

Under [53: Custom Functions (C.Fn)], if [6: Highlight tone priority]

is set to [1: Enable], Auto Lighting Optimizer cannot be set. If [0: Disable] is set, the Auto Lighting ptimizer can be set (p.261).

Even though I set a decreased exposure compensation, the image comes out bright.

Set [z2: Auto Lighting Optimizer] to [Disable]. When [Standard], [Low] or [High] is set, even if you set a decreased exposure compensation or flash exposure compensation, the image may come out bright (p.119).

When I use the <f> mode with flash, the shutter speed becomes slow.

If you shoot at night when the background is dark, the shutter speed becomes slow automatically (slow-sync shooting) so that both the subject and background are properly exposed. To prevent a slow shutter speed, under [53: Custom Functions (C.Fn)], set [3: Flash sync. speed in Av mode] to [1: 1/200-1/60 sec. auto] or [2: 1/200 sec. (fixed)] (p.259).
