Originally posted by GeneV That part had me scratching my head as well. Beside the 40 years of this mount, it is probably the mount with more adapters available than any other, not to mention the folks who will put the mounts on other mfr lenses.
The point that you seem to have missed is that you can adapt all K mount lenses (and many more SLR and non SLR lenses) to a "properly designed MILC".
By sticking with the K mount for the K-01, Pentax dropped one important advantage that MILCs have over SLRs - the ability to use lenses from pretty much any system designed during the film era. And SLR lenses can even gain
tilting capability when adapted to these new mounts.
Instead, the K-01 offered the ability to use K lenses when the interest in that was already limited to a dwindling Pentax customer base. So the K-01 catered to a niche of what was already a niche market. That was a successful recipe for failure.
The main contribution of K-01 to photographic history is that it created a category of its own - the "improperly designed MILC". Now, if one wants to make a generic statement about the capability of MILCs, they have to add "except for the K-01".
Also, the K-01 showed that no matter how many PF users saw it as a good idea, in the end they did not amount to a viable market worth catering to.
Good riddance! Let this be the last bad new product carrying the Pentax brand.
