widest horizontal angel of view?

[Thilo Resenhoeft <thilo_resenhoeft@xxxxxx>]

Hi everboy out there,

i've a question about distortion-free
panorama-cameras. Because i dislike
the distortions with widelux, horizont
and noblex, i like to know witch
panorama-camera produces the widest
distortion-free horizontal angel of view.

And - in addition - : Are there principal
frontiers that make it impossible to construct
"wider" lenses/cameras?

And - third - : Witch Objectives on the market
offer the "maxiumum distortion free angel of view"
(35 mm, medium-format, large format)?

Thanks for help,
:-) Thilo
