When zoom level increases, K1 and K2 will most likely very quickly become zero, if not zero already.
It is recommended that you back up and archive your projects in a version-controlled storage, as well as your lens calibration files.
NO will likely linearly drop until zoom = 1.00. Please note that NO can be positive or negative.
For certain lenses, FL behavior (or other behaviors) is erratic and doesn't follow smoothly when zoom changes. These lenses will likely require irregular samples. For example, the lens behavior might be very smooth between zoom levels 0.0 to 0.55, but jagged between 0.55 and 0.65. In this case, add many samples as necessary in this range to model the behavior.
Certain lenses have jagged center-shift behavior. If the image center moves irregularly when zooming in, add more center shift samples.
For most lenses, focus breathing is highest at high zoom levels. On lower zoom levels, a single focus sample may be sufficient, but for higher zoom levels, at least two focus samples will likely be necessary.
On most lenses, focus breathing can be modeled by considering that it only affects FL. However, on certain lenses, NO, K1/K2, and even CS are prone to focus breathing.
On certain lenses, focus breathing is non-linear in how it affects FL. In those cases, add more focus breathing samples to model this behavior.
