Originally posted by aikaarska I think he got tired when saw forum reaction ... He is an experienced photographer who knows what he is doing.
Indeed, that is a shame. Despite having had some robust discussions with him in these forums (and this thread), I like him - and he's clearly a very capable photographer indeed.
I will say, though, when posting on a brand-specific enthusiast site and making bold and provocative claims about poor performance, one ought to provide solid validation of those claims - or expect some pushback. The OP has posted claims and criticism about other Pentax cameras he's used, which - as it turned out - related to out-of-specification useage and his expectations. That caused quite a backlash (understandably), and so there's some history behind the reaction he's received this time.
It could be that he's absolutely right - there may well be a loss of detail as a result of the K-1II's image accelerator. We just need to see more evidence before that claim is made, ideally with identical K-1 and K-1II images taken side-by-side, and processed in a variety of software with zero default edits such as sharpening, noise reduction etc. Until then, it's merely a suspicion.
I genuinely hope the OP comes back and continues to provide information on this - or, if not, to at least continue contributing to the forum. He's valued here, like all our other members
