Re: widest horizontal angel of view?

dear thilo-the longer the focal length  of the scribing lens the greater the imaginary drum. the 1972 pos-cyclopan data sheet explains this very well. their use of 210mm f.5.6 schneider lens enabled me to reach out and grab a smaller arc of the 360 new york city skyline shot for proposed united nations postage stamp. i did not shoot full 360s. just the other side of the river from long island city. full 360, as you know with 210mm lens would be 52.5 inches of 70mm film. wasteful, unnecessary. short lens makes compact camera with small lens and with shorter focal length. cirkuit guys know where it is at when it comes to client selling detail. a picture i did on assignment for 1974 "a day in the life of america,"  not used, but in time,inc files and published in time magazine after the fact and to my surprise, yes i was paid, shows the moving lens camera inside the lockheed 1011. it is nifty picture..moving lens camera, 2-1/4x7" of film in curved plane, 80mm lens. works. i can xerox it and snailmail this to you. other curved film plane pictures of mine are in time inc publications. if you print what you take large enough to stand in the middle of it you really can't  call it distortion, but rather continuity of perspective. if you have studied 360 drawing you then know that by raising, lowering horizon, separating and moving right and left points of perspective you can make your subject matter do anything you like. i have the center of ginza street, full 360degrees on 9" 70mm film. you speak. simon      further, when we set up specs on hulcherama (after prototype which had film on drum which rotated) i said that it needed manual switch to permit more than 360 take. wanna know why?

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
