You don't want to read the sensor in the middle of an exposure, do you ?

Interesting. Do you know how the backs are controlled? My guess would be
that either they use X-synch from the lens to signal the back when capture

been saying that 645 is designed as a superior FIELD camera.
I don't think a digital back as final 645 solution make much sense. Firstly, you can
cut 25% off the 645 size be removing the film insert.

No it is not two small sensors glued together, at least that I have heard.
Most of these ICs have leads coming out all four edges so it would be hard
to do that (we are talking the chip now, not the package). Big chips have

Welcome to Pal Land! In Pal Land interchangeable back means you can
change the back of the camera; like putting a data back on an LX. This

Pentax holds all it's international distributors by the ears, I think. That
phrase about disclosure could have been used by the Norwegian distributor as

The lacking of a digital SLR is the best example of the critical situation.
However,
my idea about nothing REALLY new to be shown at Photokina is general.
According to my Pentax sorces, they don't have the foggiest idea

Another patent (US
