Totally redesigned electronics? You cant be very understanding of electronics design or serious, why would you EVER totally redesign the electronics to add a simple single modification? Thats 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 wouldnt even have to be a good one, 8 bit analog/Digital conversion would be more that sufficient. Thats 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, thats 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 thats beyond belief that you could really mean that.. And one more thing, since we dont 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 -----Original Message----- From: Pål Jensen [mailto:[EMAIL PROTECTED] Sent: Tuesday, September 20, 2005 5:59 PM To: [email protected] Subject: Re: RE: Petition to Pentax? (was Re: How Pentax Could Survive) 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. Pål
