Carsten,

They are a free set of tools called 'Panorama_Tools', 
written by Helmut Dersch.  You can download them (wintel 
or mac) from:

<http://www.fh-furtwangen.de/~dersch/>

How to use them?  Use the 'remap' tool, remapping
from 'Fisheye hortz' to 'normal', using the
following co-ordinates for the Leitz 16mm lens:

FOV long axis = 140-degrees
FOV short axis = 92-degrees

(FOV = Field Of View).

BTW, don't think because they are freebies that they
aren't any good.  Quite the opposite - in fact the
latest 1.5b4 can give image quality an order of
magnitude better than similar commercial software!


Regds,
