Guess I'm not part of this party.
I have progressed through (and still have) the K10d, K20d, K-5, K-3, K-1, and K-70, along with the 15, 21, 35, 40, and 70 compact prime lenses. Great results and enjoyment from them all.
While the full-frame K-1 delivers, I often carry the K-70 because of its smaller size, full-articulated LCD screen, and built-in flash. FWIW, my go-to lens has always been the 21mm.
Oh, and I don't do video or zoom lenses (I'm 76 years old and been in photography since I was a teen.)
