I agree, for the beginning they can get away with few lenses, and a sensible roadmap.
Originally posted by Fogel70 APS-C cameras sells in much higher volumes than FF, so this is less of a problem for APS-C. But it shows that Pentax has to use same parts in many cameras to get economics of scale.
When mass-producing something you you need to go over a certain volume for R&D and other cost not to add to much on the manufacturing cost. And below a certain volume the components you buy might get much more expensive. This will most likely be a bigger issue for Pentax than Canikon when it comes to FF cameras.
The same is true for the big two; it's most visible in the D600, which can be seen as a full frame D7000.
Indeed, it's more difficult for Pentax because of the lower volumes; otherwise they would have a FF already. But I can see a high end APS-C, a FF and a DMF sharing a new, improved platform.
Originally posted by Fogel70 It will probably take years for Pentax to have a full line of FF glass.
Yes, of course. There is no workaround for this; if they'll make the FF, no matter what it'll be, they must work hard at building a lens line. Easier than launching a MILC system, though, since lenses will be shared with the existing K-mount APS-C market.
Originally posted by Fogel70 For Pentax to grow as a brand they need to be present in more types of markets, not only the DSLR market. To grow by entering new markets will probably take less time and effort than designing a FF system. It's not about giving up K-mount, it's about making Pentax grow as a brand, which will make K-mount more successful as Pentax will have bigger brand recognition.
They are already active on the compact/point&shoot, low-end MILC, small and medium format DSLR markets. Diluting their efforts by unnecessarily adding another market could not be such a good idea. If only it wasn't such a highly competitive yet highly price sensitive market...
