I know that most will yawn or throw shoes at their monitors over my post, but having worked in Japan for years, I have a certain take on the Initial release the clarification releases, and Ricoh Pentax' behavior over the past 3 years. THis is how I read the tea leaves on this round of news/fake news.
Predictions: The K mount DFA Lenses will come and will be higher on the quality spectrum than anything that we saw under HOYA. Remember the CEO's comments 2 years ago about reducing bottom end cameras AND entering/expanding the upper end of the DSLR market to the professional tool level. (since: 645Z, 645Z to 100mp coming, K-1, KP (makes total sense now), K3-xxx imminent. Flashes changing, high end glass coming.
Pentax is going to be positioned increasingly in Japan, like Leica is in its space. They (RP) are simply doing what they said they will do.
WG is dead, Ricoh branded compacts are dead, WG-M2 is likely dead unless they can pass Hero 5 specs with only one iteration (and keep ruggedization) and successfully position as a "professional's model. Theta will grow, and already could provide game changing automotive and military technology component platforms. Possible police body-cams also, with wider FOV.
Pentax will (even with alliances like Tamron), produce better glass than the market mean, sigma remains unimportant. Ever see a Siggy on a Leica?
Watch for continued cooperation with Cactus, METZ, Arca plate manufacturers, Fotodiox, Battery grip sub-cmponent makers) wildlife photo accessory firms. Another of the CEO's several years ago comments (verified by R&D) was a push to be the best choice for outdoor/ wildlife DSLRs.
MILC (unless APSc far better than 16mp) with an EVF, is not likely. FF more unlikely.
I still believe a bigger deal is to be had with RP investing in LEICA. Leica has all of the HVA characteristics that RP needs/wants, Panasonic has no mainstream DSLR (other than M43) play, and no interest in building one. M 4/3 has commodized the cheap sensor (sub APSc/FF) space.
Also I repeat the dirty little secret that SONY rarely discussed, but has underscored by it's actions... It makes cameras as advocacy products for sensor market demonstration. Their per-unit losses on photographic platforms are large.
Man is this fun. RP is just getting started.....IMHO
