You'd still have to do stop-down metering with today's MedF lenses if 
you built it around the K-mount. The aperture coupler in the MedF 
lenses defaults to full opening, where the K-mount stops down. They're 
mechanically incompatible. :-(

Hi
The thread about the MF based Pentax DSLR got me thinking, (always a 
dangerous proposition)

First, the question. If building a body for use with Pentax MF 
lenses, would the flange to sensor distance be the same as the 
flange to film distance in the film cameras?

If so, wouldn't it be possible to design a body marginally larger 
then the ist-D using either a FF 35mm sized sensor or Kodak's 
40x40mm sensor with adapters for 67, 645 and 35mm lenses. Maybe even 
using a hypersonic motor in the adapters to provide autofocusing 
for the 645 and 35mm AF lenses.

HEY PENTAX. If you're reading this list and use this Idea, you owe 
me one of them for the idea :)
