I think this is the same reason you aren't seeing digital cameras, as a
rule, coming with lenses any wider than a 28mm 'equivalent' (the Olympus
C-2020 is the only one I  know of this wide). In fact, most only have at
most a 35mm 'equivalent' on the wide end, and even there you see chromatic
aberration in the resulting images without having to look very hard. With
wider angle lenses, the rays come in at too much of a  tangent to the CCD to
work well. I don't doubt that 'digital' lenses use optics to 'straighten'
the rays somewhat, but even that doesn't seem to be enough to get high
quality images with ultra-wide lenses.

Our only hope probably lies with a different sensor technology, maybe not
yet invented, that will have an acceptance angle closer to that of film.

How long will we have to wait?
