The cost of the 25mm is certainly way up there and a bone of contention for many. It is also out of range for Pentax's customary philosophy of affordability paired with outstanding image quality and rigidity.
However, when I look at the price from a business perspective I am wondering whether we are reasonable in our expectation. All the other MFD manufacturers (Leica, Phase, Hasselblad, Rollei DFW) are charging on a price level similar to the "new" digital prices rather than Pentax' "old" MF film prices. In fact, I find myself rather fortunate to have so much 1st class Pentax glass and equipment left from the "good old film" days.
Moreover, IMHO Pentax exceeds some of the other manufacturers in terms of quality and longevity of their products. I'd rather like to see them reduce their number of product lines and keep their philosophy of high quality and affordability. I believe it's reasonable to blame Hasselblad, Phase, Leica, and Rollei/Schneider for their prices and it's rather unfortunate that Pentax is following that trend. But I don't think they are the only ones to blame.
