Originally posted by 24X36NOW A lot fewer people are going to buy a MF Pentax than a FF dSLR Pentax. The MF market is a lot smaller, and the product is going to be a great deal more expensive to produce. Amazing to me how all those arguments about how pricey sensors are and how many fewer you get from a wafer are suddenly forgotten by those who cheerlead the MF product (that they won't be buying, for the most part) as being a great way for Pentax to prosper, while naysaying the FF dSLR as being doomed in the marketplace, because they have to "compete," as if that is tantamount to suicide or something. By that measure, they should abandon APS-C dSLRs, since they have to "compete with Canon, Nikon and Sony" to sell those, too!
Pentax needs to consider this: Those with full frame legacy lenses that want FF dSLRs in Pentax K Mount aren't going to be dissuaded from buying them by competing brands, and those legacy customers are a sizable part of Pentax's (ever shrinking) customer base. Unless they're looking to push those customers away, which is exactly what they'll do if they persist with their foot dragging, they'll do themselves no bigger favor then to get their own FF offering into the market as soon as they can. An enthusiast-level FF body (similar construction to the K20D) can sell well below 3K and will do a great deal more to keep Pentax in the game than any MF offering.
I will agree with you that an FF DSLR would sell better than an MF DSLR, but I don't see how they're pushing away most of the existing consumer base (some, maybe, but not most) by not having an FF DSLR *now*. Only the more advanced photographers appreciate the difference between an APS-C sensor and a 35mm one, anyway, and the biggest market out there is still the entry-level buyers, who quite possibly won't need (nor could they afford) FF in the next couple of years, or even ever.
Canon, Nikon, and Sony all have the budgets, name recognition, and marketing muscle to cater to the pro-level bunch. Pentax needs to create a large user base first before showing an FF DSLR, if only because only a select few of the existing user base will buy it, and because the Pentax name does not carry as much weight with the younger crowd anymore. The K-m helps with that.
That said, I'm all for a Pentax FF DSLR, even if it's not for me.
