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

Auto

There are three methods for optimizing your lens:

1. Choose Lens Optimization from the Capture menu.

2. Choose Auto.

3. Press the OK button.

NOTE: Auto is the factory default. If you reset defaults, the camera resets

to the Auto method.

Manual

Configuring your Camera

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.

Select a Lens from the User
List

4. Press the OK button.

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.

Configuring your Camera

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 mast er
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.
