Re: cosina hopes

[Peter J. Alling]

Most of the manufacturers who used the K mount were slowly leaving the 
market, or building bargan bodies, or selling rebadged
Cosinas anyway.  Ricoh produced their own version of the A lens mount 
that isn't 100 % compatible and never built an autofocus
camera body as far as I can remember.

I just wonder if Cosina could come up with a dslr that would be fully
compatible with Pentax K and M lenses. 
     

No reason why not, since Pentax released the K mount as an open standard
(which is why Vivitar, Ricoh, etc used it). 
   

The basic K mount was indeed used by other manufacturers, but not the
KAF (with aperture contacts, data transfer contact and AF coupling).
Anyone know if this was because Pentax didn't make all this information
public or if there just wasn't interest on the part of other
manufacturers?
