Hi, Klaus,
as you can see from my post, lens distortion parameters vary with
focal length. There is a high possibility, that they also vary with
each camera of the same model. But - if they vary with focal length,
it seems to me, that they are calculated by the camera

But that was not the point of my questions/suggestions. I'm
just curious, why these parameters are not used directly by
Hugin.
Because Olympus hasn't released any public documentation on how
to use those

At least with my cameras, there is only a finite number of zoom

PTLens works with lookup tables as well and it works fine.
Why do I have to difficultly determine lens
Hi, Klaus,
my camera has infinite number of zoom positions, as it has seamless
zoom from 6.3 to 63 mm (38 to 380 mm if we speak in terms of 35 mm
camera). So it seems to me, that there is no lookup table, but lens
distortion parameters are calculated.

Hello Jaroslav,
While it is nice to have these values saved, I have found that lense
parameters vary within the same camera model. Hence I usually have
them optimised from the image data itself, which overall requires a
few more control points.
Do you have an idea what mathematical model
