STEP 3 Making adjustments: Apply the Digital Lens Optimizer effect

Step 1

Click the [Tune] button.

❶ When the indication "Lens data: Yes" appears,
❷ lick the [Tune] button to show the Digital Lens Optimizer screen.

Step 2

Adjust the Digital Lens Optimizer effect.

❷ Use the slider to adjust the degree of compensation. Moving the slider to the right will enhance the perceived resolution and result in stronger correction of lens aberration.

<Point> Shooting distance

For images taken with EF lenses which do not have distance information, an exclamation mark (!) will be shown above the "Shooting distance information" slider. In this case, optimal compensation can be obtained by manually entering the shooting distance.
When an EF lens is used, shooting distance can be entered manually also if data are available. This allows you to fine-tune the effect for best compensation.
Shooting distance information is always included for all EF-M lenses, and therefore manual input is not possible.
