So if you need a true step in technology, the solution is not a marginal increase in sensor size.
Three things to remember:
1) The difference in sensor are between 645d/z and FF is less than the difference between FF and aps-c. You get a bigger 'jump' going from aps-c to FF than you do from FF to MFD.
2) The retail price delta between lowest-end MFD ($8500, body only) and upper-end aps-c ($1500?) is about $7000 - body only, lenses expand this delta much more. Lower-end FF - aps-c delta is anywhere from $200 - $1000 delta, depending on which body comparisons you're looking at.
3) Lens purchases made for aps-c DSLRs cannot be used on MFD bodies - a Pentax FF body could mount and AF any K-mount lens.
There are very few people - less than 6000 per year worldwide, according to Pentax - who see the above as acceptable-enough, or who have specific-enough needs to buy a medium format 645 camera. This is not a viable, longtime, workable answer to FF for Pentax.

Really, I'm never upset about gear, and I enjoy these discussions. Amusement is the usual emotion
Quote: I'm of course not saying MY needs are the reference point. But neither are yours. So far, however, Pentax seems to agree with me, and I think it makes sense.
Actually, unless they're outright lying now, they see it my way.
I think the FF paralysis up until this point has had more to do with : ownership turmoil + fear of MILC disruption = institutional inertia.
As a related aside - big and small companies make strategic mistakes all the time, and I think hindsight may show us that Pentax's decision to begin to enter FF in 2015/16 vs 2011/12 was a bad one. They lost time, market position, customers, initiative. We'll see.
Quote: But they don't have dozens of employees lying around doing nothing. their resources are committed already.
There would need to be a shift in or addition of resources - but neither you nor I know how much would need to be hired/acquired/leased vs re-allocated.
Since they reportedly have FF lenses in development and ghosted on the roadmap, and have officially stated that FF is 'in development and waiting for release strategy (paraphrased,)' then they have not found this capacity issue as daunting as you do.

I'm an optical designer. I can tell you that thinking this way is naive at best.
I guess (sorry, here) I'll have to call your expertise into question, then. (Also... your arguments/data should stand on their own, "
don't argue with me I'm an optical designer/expert/physics major" is a no-op sidestep.
Going back to the D300/D700 Nikon has shown the benefits of this development and manufacturing sharing - those two bodies are very, very similar, and they've carried that forward. Firmware and UI are almost exactly the same. Nikon has talked about leveraging these synergies in tradeshow interviews. Their sharp, affordable 28/50/85mm f/1.8 lenses sell in big numbers to both aps-c shooters and FF customers. Canon has done similar things with the 6D/7D... the potential differences between similar-tier apsc and FF DSLR bodies are fewer than the similarities. Then there's the lens development, which can be shared much more tightly than 645 and something like the Q can be with aps-c.
Quote: Increasingly affordable FF is still, for the moment, twice as expensive as APS-C.
Adorama has K3 at $1000 and D610 at $1700 right now. That's not 'twice', and in fact a $700 (and dropping) body difference is getting to the point where it stops mattering to a big chunk of aps-c customers.
The big problem for Pentax going forward is that they won't be able to sell a $1500 aps-c camera in the same volume they did in 2010 - their initial early-adopter MSRP flagship margins will have to drop quite a bit, or something else will have to give. If they want to continue to sell K-mount DSLR products, they'll need FF - and they've basically admitted this now. (unless they're just lying again
)
