aragondina, Hoya is concerned about profit, not selling units
Would I like a Pentax FF? Yes, sure. Even for no other reason than a bigger viewfinder.
Would I buy it, then? Unlikely. It would still be expensive, and APS-C is past the 'good enough' for me. And I would have to think about new lenses... another substantial expense. My money would be better spent elsewhere... but, I can get quite... irrational at times; so don't be surprised if I will actually buy the hypothetical Pentax FF
What if money would not be an issue, then? That's an easy one: I would go to the 645D the moment it's on the market
But I'm not Bill Gates, and I wonder how many of those who voted 'Buy Pentax FF DSLR' are truly prepared to spend their money.
In other words, it's 'Stick with APS-C' for now.
L.E. If some Pentax official is reading this: even if I won't buy a Pentax FF, I would 'celebrate' it's appearance with a brand new expensive lens. Just to show my support
