I recall also that digital film stuff.
At the time, it looked really promising. I think I was in their e-mail
info list. Never received one.
I still hope for a full frame Digital back for Rollei TLR though. That
would be AMAZING! I checked and one can find some 6x6cm ccd array.
Some are even without bayer matrix (understand pure greyscale) and so
have an incredible spatial resolution. Some are colored, but still
have really good resolution, associated with wide pixel size, boasting
relatively the fill factor (buses are more or less the same size). Now
if Sigma could do this with a new generation backlit foveon... With
the current state of miniaturisation, that would take more or less the
size of a humpback, providing you would exploit holes of the rollfilms
for batteries (of a new dedicated format, taking exactly the 120
rollfilm size.
The major problem would be to find a sensor. The standard (not very)
size for large format Bayer color appears to be 48x36mm although some of
them are a bit smaller.
Now, to avoid that awful rear display everyone HAS to look at directly
after having taken the pic, we should find a solution to have the
image visible on the screen of the camera... Projection through the
mirror? Projection on the mirror, enough room below? Projection on the
mirror, but from where? A new kind of see-through screen, to make the
point and emitting images. Allowing as on a DSLR display to show or
not lines, indications...
Yes, just another feature of digital cameras that I don't understand.
We seem to still be in the legacy stage of development -- film
emulation. I suppose that the screen on the back is like a Polaroid
print. Why can't they build a NOT SLR with an interchangeable
electronic viewfinder. If you really want to see how the result will
look, you need a laptop anyhow. Even with a large electronic
viewfinder, you wouldn't have people looking in it.
So, yes, you could convert a Rollei TLR, but do your really need the
optical viewfinder?
