  Most are aware that full-frame sensors are available... but only having
digital backs that cost from $7,000 to $30,000 has effectively shut VH off
from 90% of their former market.  This unfortunately tolls the death knell
for VH.  Leitz at least has a $5,000 digital solution... though not near MF
quality.
  Many Fine art shooters I know have decided to stick with MF film then scan
the images and Light Jet the prints.

  Then perhaps saying "with *existing* (commercially available) digital
backs" would be a more accurate claim.

  BTW, the "full frame" sensors *are* available.  I have a few.

    Sofar there are only digital backs available with considerably smaller
sensors
    The often used CFV back from Hasselblad performs excellently with the
SWC.
    Backs now availble with a mount suitable for Hsselblad have smaller
sensors.

    Lets talk about full frame 56x56 mm sensors as soon as they are
available.

      Hi Flex,

      I'm not sure I agree with that.  IF the digital back has a
(significantly) reduced sized sensor, possibly.  But I'd question that a
full frame sensor would not have significant vignetting on the corners.

      Regards,

      Austin

        The difference between theory and practice.
        Any SWC will produce excellent results with a digital back.
        Even the first camera in that series,the SWA, will go well
        with a digital back.

          I’m not an engineer, but I would venture a guess that with the
Biogon being as close as it is to the film plane, you’d run into real
problems using one for digital capture.  Sensors tend to be real finicky
about the angle of light (a distinct advantage to film).

          It is not the price of the sensor that is important for the price
of a digital back.

          Sensors are only a fraction of the total cost of a digital back.

          I guess a full size sensor would not cost more than 600USD of
ordered in quantities.

          Other problems will make a full size back for MF expensive.

          Power needed to feed the electronics will go up considerably.

          That makes large capacity batteries necessary.

          Just one ot the problems that are often overlooked.

            Digital or not... the SWC's 38mm Biogon can probably still beat
the pants off any wide angle lens ever made.

             I think the there would be a market for a tech start-up to make
a Hasselblad specific Digital back to work with and 500/swc series body.  I
know the chips are out there.  5 years ago I held in my hand a CMOS detector
that measure 5" square.  It was comprised of four  2.5"  CMOS detector
plates joined together.  It was a high-gane photographic detector  for the
Keck telescope in Hawaii.  If that plate  was operation 5 years ago then the
technology is WAY beyond that now.  producing a 2-1/4 X 2-1/4 full frame
detector that could sell for less than $1,000 should be well within reason
today.  If Hasselblad or leaf won't do it then someone should
