Originally posted by jatrax "semi-pro" would indicate APS-C probably. But "between k-5II and the 645D" could also indicate FF. But I'm not sure if that quote is idle speculation, wishful thinking or a hint intended to start rumors.
At this point I find that I no longer really care. I have all the APS-C lenses I want or need and an assortment of FF lenses. I have looked and really do not find any Pentax FF lenses in the database that I would even want to purchase. If Pentax does come out with a FF and if I feel it is good enough to warrant moving to it then I'll need 24-70 zoom to go with my current FF primes. But there isn't one out there I want at this time so I'll just wait.
For those who want FF camera from PENTAX, like me, is important ...:-) since I will have to decide if I should continue to "invest" in APS-C lenses (e.g. deciding if I should get the Sigma 18-35mm, Sigma 35mm f1.4, no interesting lenses from PENTX, sadly), or save the money for FF cameras and lenses (moving away from PENTAX or wait).
Not a single lens purchase since last year's Oct (I think), and every time I saw a lens in the marketplace that I want, I would think "I will wait and see what else PENTAX bring"...
