I think you are seriously overestimating the difficulty in producing/devloping a M42 DSLR, the only signifigant difference from a K100D would be a screw thread flange instead of a K flange and a M42 pin actuator instead of the k lens lever actuator. Nearly all of the remaining hardware would be the same and the software/firmware would be mostly deleting existing features M42 couldnt do. jco

Even if everybody who wanted one and was willing to pay for it (that'd be you and maybe 10 other people on the planet), it'd probably have to cost $20K to make back the engineering costs. It's a similar thing to aircraft avionics. What amounts to basically a well-built CB radio costs $2500 new. A similar model costs $1000 for a used one that's 25 years old. The few companies who produce these low-volume devices charge a lot more than what they would if they were commodity. In some cases (like portable GPS's), for almost identical hardware to a consumer-grade on that costs 1/10th the price. -Cory -- ************************************************************************ * * Cory Papenfuss, Ph.D., PPSEL-IA * * Electrical Engineering * * Virginia Polytechnic Institute and State University * ************************************************************************ * -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
