First, your camera brand is not popular enough for C1 - but neither are PhaseOne bodies for the majority of us. For which Capture One was programmed originally. Of course you have a different opinion on that, but I don’t recall to have seen a Pentax somewhere else than in the 2nd hand shelves during the past 5 years. Although pretty capable cameras, this brand is no longer “popular”, just check different shopping malls.
Second, if you compare an app with a lot of features another app doesn’t have and this other app need (!) additional apps at additional costs to deliver the same spectrum of features, you’re not acting exactly fair. But I’m glad you found your RAW converter of choice.
Capture One was probably sponsored by Fujifilm, SONY and Nikon. Some customers who stepped into the C1 realm because of the cheaper versions will stay onboard, others abandon ship, so far, so normal. But if a lot of these come to DxO PL with it’s rather limited functionality without FilmPack and ViewPoint, not to mention the less than lousy DAM – that remains doubtful.
Btw., it’s not “your” brand, but Ricoh’s, and they want to go the “customizing” way, like they did with all the colourful plastic bodies. Why don’t you ask “your” brand for a decent RAW converter? I know, each Pentax user defends “his” brand til the bitter end, but somehow the question remains unresolved why “your” brand became insignificant? There was a supercool LX, a very great 6×7 decades ago and… well, the Km, Kr, Kx simply didn’t deliver enough reasons to not switch brand 12 years ago. Time always moves on. Companies less so.
