But the LX was the last really pro-level Pentax, since then Pentax has been strong in the prosumer market with the Z-1(p), the MZ-S and now the K10D. For a decade, pro-level in Pentax words has meant the medium format 645 and 67 systems.
I think they will build up their "strong prosumer" image by continuing to differentiate their cameras from mainstream makers and provide unique features, handling and quality levels for that market, just like they have for some time. They will attract the types of pro that dont need big, heavy machine gun cameras but who do need very high quality, robust engineering and image quality in a more convenient package and in the meantime pick up a lot of well informed enthusiasts along the way.
A modern day M2? Mmmmm yes please.
