It should be noted that some bills are not gone though. We need a new fiscal diligence to make things better for good. The K-1 would be a great choice if income from photos were to come with it, and that's something I cannot guarantee. However the K-3ii now feels more reasonable as a choice with nearly the best of everything!
How do they compare?

The K-3 is just a pinch bulkier than my K-5 that fit so well, but a few buttons and dials have changed. Everything is larger in the K-1: sensor, SR system (better stabilization), screen (with tip and pivot!), number of control dials (3) and of course, price ($1k more±). Each have the new Pixel-Shift mode that provides full color data to every pixel, but the K-1 can correct for moving objects in camera.
However II: the Pentax computer software can correct for motion on both cameras! This is a recent discovery and really makes the 3ii a more appealing option. The best possible images, APSc size for body and lens savings, 24Mpix (actually more pixel density than the K-1's 36Mpx but gentler on the hard drive) and a similar feature set.
The one thing for sure is that a K-50 bargain body arrives tomorrow. I had considered sending it back for a time, but we have many financial decisions to make before the camera hits the agenda. The K-50 uses the famous sweet-16Mpx sensor, uses pre-Ricoh controls that I have used for years, has weather seals and does a fine job where it counts.
For a few months at least, the K-50 will do just fine.. and it will feel quite familiar!
