I had the same camera and I've exactly same numbers here, so I don't
think that lens distortion parameters vary. IMHO it only can only look
like they vary because this camera has as Jaroslav said connected zoom
and It shouldn't
Hi, Markku,
so I'll try to get some info from Olympus - perhaps nobody tried
before, so that's why we don't have any documentation or info on that.
In the meantime I will try to find some corellation between those
numbers in exif and Hugin.
Regards
Jaroslav

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.
Regards
Jaroslav

PTLens works with lookup tables as well and it works fine.

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 during the
shoot.
But that
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 corresp
