Introduction

What is AF Microadjustment?

It is a function that makes it possible to make fine adjustments for the AF's point of focus when using AF during viewfinder shooting. You can select from two types, "Adjust by lens" and "All by same amount."

AF Microadjustment important information

The AF point of focus may vary slightly due to shooting conditions such as subject conditions, its brightness, and the zoom position. Therefore, even if you perform AF Microadjustment, the point of focus may not always be at the suitable position. If you feel that focusing errors are not fixed after using this function several times, contact a Canon service center. We appreciate your understanding that if repairs are necessary, there may be a charge.

• Adjusted content has no effect in the AF during Live View shooting or movie shooting.

Even if the camera settings are reset, adjustment content will remain, however, settings will be set to [Disable].
