Initialize Calibration

With lens zoom at full widest, select a focus level in which the marker features are distinguishable in min and max zoom.

Fixed Focus Level

Try to find a fixed and comfortable focus level and use it for all calibrations except for focus breathing. Most likely, a focus between 0.85 to 1.00 will be fine.

Process

• Launch the Lens Calibration panel.
• In the second top row of the panel, click Reset.

Lens Calibration Reset

• In the popup that opens, override the Min Focal Length and Max Focal Length if you already know these values; otherwise, leave them as they are.
• Click OK to reset the lens calibration.
• This will reset all Focus values to the current Focus value of the lens.

Now, the system is ready for calibration.
