None, to all intents and purposes. If you look at the amount of support circuitry on a sensor (other than the per-pixel stuff, which needs to be there no matter hom many individual pieces the sensor is made of) there's hardly any - a few latches, and the A-to-D logic. Having, one, two, or four copies of those circuits is at most going to add a few pennies to the total cost. > > Aligning two CCDs comes with it's own set of problems, I guess. > > Jostein > > > > On 8/29/06, Takeshita K <[EMAIL PROTECTED]> wrote: > > Nevertheless, my understanding is that the cost of the FF size > > sensors is at least 10 times (or more) that of the APS sized one, > > and this gap is not going to narrow any time soon. > > -- > PDML Pentax-Discuss Mail List > [email protected] > http://pdml.net/mailman/listinfo/pdml_pdml.net -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
