Colleagues,

I don't know anything about ultra-wide lenses and have questions. For a
rotating panorama camera does it matter if a lens is flat field or fisheye
since a narrow vertical aperture is used?  The choice is between a 15mm
Sigma fisheye and a sigma 14mm flat field.  Are their optical qualities of
fisheye lenses that make them unsuitable for a panning camera? btw anyone
know a url with data on these lenses?


Definately go flat field.  The fisheye distortion will compress the image
towards the edges.  Also the film will not be in synchronization with the
rotation as it moves across the slit near the edges, causing bluring.
