Using the Digital Lens Optimizer
This function enables the resolution of images to be increased by removing any remaining aberration related to image-forming capability or any deterioration of resolution resulting from diffraction phenomena that are unavoidable as long as light must pass through the lens. These optical phenomena cannot be corrected under [Lens aberration correction]. Correction is achieved using the designed value of each lens. The images that can be corrected are RAW images shot using any of the "compatible cameras" and "compatible lenses". JPEG, TIFF, S-RAW, and M-RAW images cannot be corrected. For details on compatible cameras and lenses, refer to the "Digital Photo Professional Instruction Manual" (PDF electronic manual). To use this function, [Lens data] for the lens used to shoot images first needs to be downloaded to your computer. Before using the Digital Lens Optimizer, it is recommended that you set [Sharpness] or [Strength] for [Unsharp mask] for images to 0.
-
The Digital Lens Optimizer is also available for images shot with an extender mounted on a compatible lens.
-
You cannot use the Digital Lens Optimizer with multiple-exposure RAW images created on the camera.
-
EF cinema lenses (CN-E lenses) are not compatible.
Using the Digital Lens Optimizer
In the tool palette, select the [Lens] tab sheet, and check the status of [Lens data] for [Digital Lens Optimizer].
-
[Not Available] is displayed for an image shot with a non-compatible camera or lens, or for a non-compatible image such as a JPEG, TIFF, S-RAW, or M-RAW image. The function cannot be used for these images.
-
If [No] is displayed, proceed to step 2. To use the function, you need to download [Lens data] for the lens used when shooting the image. It is recommended that you check the lens used when shooting the image beforehand. The lens used can be checked using the [Info] button in the toolbar on the main window. You can also check it with the menu that appears when you right-click with the mouse on an image.
-
If [Yes] is displayed, proceed to step 4.
-
Click the [Update] button.
-
The [Add or Remove lens data] window appears.
-
Checkmark the checkbox for the lens used to shoot the image, and click the [Start] button.
-
The lens data is downloaded to your computer.
-
When the downloading of the lens data ends, the indication for [Lens data] changes to [Yes].
-
You can download the data for up to 30 lenses at the same time.
-
If you remove the check mark from the checkbox for already-downloaded lens names and click the [Start] button, the lens data will be deleted from your computer.
-
Click the [Tune] button.
-
The [Digital Lens Optimizer] window appears.
-
Checkmark the [Setting] checkbox and adjust the image.
-
When the list box for selecting an extender is displayed in the [Digital Lens Optimizer] window, select the extender attached at the time of shooting from the list box.
-
Use the slider to adjust the Digital Lens Optimizer effect.
-
When [MAX] is displayed for the Digital Lens Optimizer level, the effect will remain the same even if you move the slider further to the right.
-
You can change the display position of the check window by dragging the enlargement display position in the navigator window.
-
Even if you set shooting distance for a lens in this window, the value indicated for shooting distance in the [Lens aberration correction] window will not change.
-
If no shooting distance information is saved to the image, the shooting distance slider is set automatically to the right end at infinity position and a [<!>] appears above the shooting distance slider.
-
Images cannot be corrected for [Chromatic aberration] in [Lens aberration correction] if the Digital Lens Optimizer has been applied.
-
Click the [Save] button.
-
The [Digital Lens Optimizer] window closes and correction results are applied to the image in the edit window.
-
Corrections made in the [Digital Lens Optimizer] window are also displayed in the tool palette.
-
In the main window, the [
] mark is displayed on the image to indicate that the Digital Lens Optimizer is applied. -
After clicking the [Save] button, the application of the corrections to the image may take some time.
-
The size of the image file will be larger after applying the Digital Lens Optimizer.

To use this function, an environment with Internet access (subscription to a provider, browser software installed and an in-place line connection) is required.
-
An administrator-level privilege is required for this operation.
The [Setting] checkbox will be checkmarked if the image has the Digital Lens Optimizer already applied. Remove the checkmark and click the [Save] button to cancel the Digital Lens Optimizer.
-
Images displayed in the [Digital Lens Optimizer] window are with [Sharpness] and [Unsharp mask] effects applied by default. If you checkmark the [Do not sharpen previews] checkbox, images are displayed without [Sharpness] or [Unsharp mask] effects applied, allowing you to check only the Digital Lens Optimizer effect.
-
When applying the Digital Lens Optimizer, the effect of [Sharpness] or [Unsharp mask] may become excessive. It is recommended that you set [Sharpness] or [Strength] for [Unsharp mask] for images to 0 before using the Digital Lens Optimizer. Adjust [Sharpness] or [Unsharp mask] again after applying the Digital Lens Optimizer to images.
