Originally posted by MJKoski No I do not say FF is best solution for everything as it has wrong aspect ratio to begin with. My point of view is that Pentax *excels* at base ISO imaging. Therefore:
1) Sell all crop gear
2) For tripod (or otherwise slow paced shooting), get used K-1 MK1 and few suitable FF-lenses
3) For anything else, switch to mirrorless
Has it been proven/hinted by a 3rd party that K-3 MK3 improves AF (tracking)? And IF it does, with what lenses? How will the old screw/SDM drives respond? What are the other reasons to buy the MK3? Better IQ? Sure bet against K-3 MK2, not so sure against KP. KP pulled quite a stunt with its base ISO IQ.
For me, I'm going to kick that can a few years down the road with the K-3iii. If the autofocus performance is anything like it's being billed, I think I'll be pretty happy with the new APS-C and the 55-300PLM. Perhaps the 16-50 PLM in the future, and I can dream of a 50-135PLM.
If I follow your path I'll be spending months and months trying to sell off everything in pieces, and then switch systems for theoretical gains in some areas with mirrorless, after I've learned the new system and spent a bunch of money. I think the far easier solution is to just buy the new camera that appears to be designed for my shooting style. Then in 3, 4, 5 years maybe my kids won't be playing sports and I'll figure out what, if any, requirements aren't being met by what system I have then.
What you're saying is that nobody should buy a K-3iii, so Pentax probably is doomed after all. I'm a little surprised that there's a market for a Pentax camera designed for me. But we'll see.
