The main lens values Previzion uses are:

• Focal Length

• Field of View (derived from Focal Length and Sensor Width)

• Focus Distance

• Entry Pupil (often termed the ‘nodal point’ of the lens)

• Center Offset X & Y (distance from the center of the sensor to the optical axis. A measure of lens misalignment in mm.)

• Distortion R2 (the first order radial distortion of the lens)

• Iris (F stop)

• Depth of Field scale (1.0 is physically realistic.)
