[HUG ] Re: Biogons and digital backs

Before I purchased my Phase back I talked to the technical people at Phase and 
they asure me that the IR/AR filter installed on the sensor will handle the 
SWC's biogon design, even the new P65+

  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
