[HUG ] Re: Biogons and digital backs

As I recall, the discussion was on the expense of producing a full-frame
sensor.  That would be the reason for my concern about the angle of light to
the edges and corners of the image.

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
