Lens Optimization
Overview Some lenses produce a color shift in the corners of images. Your camera
has a feature that corrects this color shift to create a more uniform image.
There are three methods for controlling the strength of this correction.
Method one: Auto—(see page 5-28) This method automatically
determines the correction strength for each image based on analysis of the
image data. This feature works with most lenses and may be the only
method you ever need to use. When the camera is in Auto, all of the work is
done for you.
NOTE: The Auto method is recommended if your images are not showing
anomalies.
Method two: Manual—(see page 5-29) This method allows you to
directly input the correction strength. This method is provided for testing,
and is not for daily use.
Method three: Lens Selection—(see page 5-29) This method
determines the correction strength by selecting the specific lens you are
using. Since the camera cannot uniquely identify every lens attached, you
must select the lens from a list. Your camera contains a master list of
commonly used, current model lenses from several manufacturers. You
can easily add additional lenses to the master list. There is a conveniently
accessible user list for the lenses you use most often. The camera can
usually automatically identify and select the current lens if it is in the user
list. It is easy to maintain this list by adding and removing lenses.
The master list includes default correction strengths for each lens.
Sometimes these defaults are not ideal. You can adjust the strength for any
lens in the master list. If you define new lenses (see page 5-35), you will
need to set the strengths for them as well.
We recommend that you try the Auto method first and only use the Lens
Selection method if you are not satisfied with the results of the automatic
optimization.

Selecting the Method of
Lens Optimization There are three methods for optimizing your lens:
Auto

to the Auto method.

Manual 1. Choose Lens Optimization from the Capture menu, then choose
Manual.
2. Press the right side of the Four-way switch to display the edit boxes.
3. Press the right or left side of the Four-way switch to highlight a box.
Press the top or bottom of the Four-way switch to change a value.
NOTE: The strength must be between zero and 99.
4. Press the OK button.
Select a Lens from the User
List Once you add a lens to the user list (see page 5-31) or define a new lens (see page 5-35), you can select it.
1. Choose Lens Optimization from the Capture menu, then choose a lens.
2. Press the OK button.
NOTE: Most long lenses require a correction strength of zero. Select the
>85mm option for these lenses. This is more convenient than
adding all your long lenses to the user list. If you have a long lens
that requires a non zero strength, add it to your user list.

When you Change Lenses If you have selected a lens from the user list and you later change the lens,
you should select the new lens before shooting. If you capture an image
and the lens does not match your selection, the camera will attempt to
automatically select the new lens. The camera will ask you for help if it is
uncertain which lens you are using. One of the following events will occur:
• If there is one possible match in the user list or the master list, that lens
is automatically selected.
• If there are two or more possible matches in the user list or the master
list, the list of possible matches appears.
• If there are no possible matches in the user list or the master list, the
camera switches to Auto.
NOTE: If you use the wrong lens in Basic mode, the Auto method will be
used.
With two or more matches:
1. Press the OK button to dismiss the screen.
2. Select a lens and press the OK button.

Maintaining the User List The camera maintains a master list of lenses. You can create your own user
list of frequently used lenses.
You can do the following with the user list:
• Add lenses from the master list (see page 5-31)
• Remove lenses (see page 5-33)
• Select lenses (see page 5-29)
• Save the user list (see page 5-34)
• Load the user list (see page 5-34)
Adding Lenses from the
Master List Use this option to move a lens from the master list to the user list.

choose Add Lens.

The lens is moved from the master list to the user list.

Saving a List If you have made any changes to a list in the camera, we recommend that
you save the list to a memory card. This combines the user list and master
list and provides a backup copy. If your camera needs repair and the
original list cannot be saved, your backup copy can be loaded.
If you use more than one KODAK PROFESSIONAL DCS Pro SLR/n Digital
Camera, you can save time by creating the user list of commonly used
lenses on one camera, then loading it into the others.
1. Insert a memory card in the camera.
2. Choose Lens Optimization from the Capture menu, choose Setup, then
choose Save List.
3. Press the OK button.
The list is saved to the root directory of the memory card as lens.txt.
IMPORTANT: Do not edit or rename this file. If you do, it may not
work properly in the camera.
Loading a List IMPORTANT: Save your current user list to your computer before
loading a new one. The new list will be merged with
your current list and new lenses or changes not already
in the camera will be applied. If you change the
strengths for a lens, and there are changes for that lens
in the new list, your changes will be overwritten.
1. Insert the memory card containing the list in the camera.
2. Choose Lens Optimization from the Capture menu, choose Setup, then
choose Load List.
3. Press the OK button.
4. Press OK in response to the confirmation screen.
If a file named lens.txt is in the rootdirectory of the memory card, it is
saved to the camera.
