Some comments re Phillips 24x35 ccd.
I guess that the fact the sensitive surface is about 2.5 mm
behind the surface of the package is what makes
interchangeable digital backs difficult. Probably not a
problem with an in lens shutter because the sensor could be
recessed into the camera, but a foca
My concerns deal with compensation for the
mechanical shutter and problems related to it.
Here's some issues:
#1 -- One roadblock that I faced was dealing with auto-exposure
mechanisms and curtain travel at higher shutter speeds (you end up with a
slit).
How are you dealing with this problem? M

I saw Sony is starting with 8cm CD-R recorders build into their camera's.
That might be an interesting concept.

I agree.. build it into a replacement back. That's what original

1st let's take a look at the price of components and PCB, the Philips unit
A 36mm x 24mm sensor would be nice, but what about using a smaller sensor
and some glass to compress the 24x36 image onto it? Or how about an array
of smaller CCD sensors and, if needed, some optics to direct the image away
from the seams?
If you're putting an LCD preview screen
Well let's put it like this
just my electronic design charges for a similar project would be around
75KUS to 90KUS...
including, firmware, and computer software...
I have a net profit way higher than Pentax ;-) and pentax has to spread that
X00K+ on
a lot of machines... I don't
