Troubleshooting Guide

There are fewer AF points.

Depending on the attached lens, the number of usable AF points and patterns will differ. The lenses are categorized into eight groups from A to H. Check which group your lens belongs to. Using a lens in Groups F to H will have fewer usable AF points (p.76).

The AF points are blinking.

When you press the <S> button, the blinking AF points are those that are not cross-type AF points and are only horizontal line-sensitive. The AF points that light up are cross-type AF points (p.71).

The AF point at the registered area is blinking (p.338).

I cannot lock the focus and recompose the shot.

Set the AF mode to One-Shot AF. Note that focus lock will not work in the AI Servo AF mode (p.67).

The continuous shooting speed slows down.

At the <o> setting, the maximum continuous speed will be approx.

10 shots/sec. if the ISO speed is set to any of the following:

ISO 32000 or higher is set manually.

[Auto ISO range]’s [Maximum] is set to [51200] and Auto ISO automatically sets ISO 32000 or higher.

[81: Safety shift] is set to [ISO speed] and the safety shift automatically sets ISO 32000 or higher.

Note that if the camera’s internal temperature is low, and when ISO 20000 or higher is set manually or automatically, the maximum continuous shooting speed for <o> will be approx. 10 fps. Depending on the ISO speed, shutter speed, aperture, subject conditions, brightness, lens type, etc., the continuous shooting speed may become slower.

If [Auto AF pt sel.: EOS iTR AF] is set to [Enable] (p.95) and you shoot under low light, the continuous shooting speed will decrease.
