Originally posted by richard0170 I don't see why there should be much increase in either size nor cost. As far as cost goes, the glass is already there and needs no development. Regarding size, the much bigger and brighter viewfinder of things like the ME Super or MX are much smaller than the pentaprism housing of the KP. You could lose the built in flash if you were concerned about the size of the housing. Of course what I suggest is never going to happen. I was just idly speculating "what if?"
Yeah, I think I misread your original post - I was thinking of a K-1 version of the K-3 III prism, which is
not what you stated. You're suggesting the prism of the current K-1 be used in a KP II. That does make more sense to me, and would be a nifty feature... but I do think there would be howls of discontent at the removal of the built-in flash in a "consumer level" DSLR.
From what I understand, the KP was the "mirrorless fighter" so anything that would increase the size and weight would run counter to that mission, but perhaps Pentax will re-think that with the next APS-C DSLR they release.
Maybe you should pass your suggestion on to Pentax, as it is a "photographer-friendly" feature, and that is the image Pentax is cultivating.
