[HUG ] Re: Biogons and digital backs

Austin,

I have sensors that will cover 4"x5".
That is not the point, sensors are not the bottleneck.
If anybody knows that it would be Austin.

Neither is the technology a problem. 
It is the economical/marketing question that is
blocking full frame sensors for MF.
Sofar progress and competition have given us a nearly
full frame 6X4.5 digital back.

The other solution is still open and calls for action 
from Carl Zeiss  or Schneider to name a few.
Shorter lenses to give true Wide Angle performance.
That was the same trend that followed smaller than
full frame sensors in 35 mm based DSLR.

Hasselblad came with a 28 mm the widest lens sofar
not counting the 30 mm fisheye for the V series.
Whether you like the DAC system or not the 28 mm 
lens is there.

  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.

  Best Regards,

    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
