[HUG ] Re: Biogons and digital backs

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
