Sounds like a tradeoff between super expensive lenses and
somewhat larger image sensors, right?
Are larger sensors out of the question because they result
in bulkier cameras?
I would think a VistaVision format digital camera would
create images well beyond what's needed for 1080p, and with
quite affordable lenses.
As far as I know, there's only one still digital camera
that used a full-frame CCD sensor (like VistaVision): the
Contax N digital, 6 Mpels, withdrawn from the US market in
2003.
