Totally redesigned electronics? There would be no need to totally
redesign
the electronics to add a simple single modification? That’s certainly
not
necessary. nowadays there are a lot of processors and controllers
(most of
them?) that have a whole bunch of on chip ANALOG and digital inputs
and this
part would only need one channel of those and it wouldn’t even have
to be a
good one, 8 bit analog/Digital conversion would be more that sufficient.
That’s why I said all it would take is a
single A/D channel on the processor.
What's confusing the issue is are you talking
about actually modifying the the istD exactly
as it is or a new CAMERA design which intends the feature
from scratch? A even new camera design which intendes the feature
from the
start would NOT be a total redesign it would be a simple very minor
modification to get the sensor data to the processor, that’s all.
This is
way more simple than you are making it out to be, need for total
redesign is
out of the question. I think you have to be using the wrong terminology
because that’s beyond belief that you could really mean that..
And one more thing, since we don’t know when the decision
was made to not include the cam sensor in the camera
on the final production model, the interface electronics
may ALREADY there on the current design and ready to go WITH ZERO
CHANGES NEEDED AT ALL except adding the
pot assembly and the the software to read the pot and apply the desired
function, both of which are extremely simply processing... jco

I honestly don't think it would help because I think
they ALREADY KNOW what they have done and the decision
was made with full knowledge. As to whether they
offer a DSLR body with full Pentax lens support, that's
another decision but if you think about it , they could probably
charge a
couple of HUNDRED dollars more AND GET IT, for only a $5 part they
took away
so
REPLY:
It is far more than a few dollars. Using the older resitor based lens
interface maens totally redesigned electronics. The metering and lens
comunication are totally digital with newer bodies. Complete K-mount
compatibility means building in two systems. In addition the
production cost
are much higher with mechanical systems. Theres no way that Pentax
will buld in a complete mechanical interface with
the lenses (in addition to the electronic) on a product in a price
sensitive
market. The reason is that the competition doesn't. If Pentax makes
full
lens compatibility it will be on a high-end body.
