If you don't have a budget for new lenses, the 16-50 will have to be used in crop mode and the 60-250 in full frame mode will have some strong vignetting unless you modify it for full frame use. So you would be buying a heavier fancier k-5ii in effect.
I agree and disagree at the same time.
The crop element is perfectly true. However, the K-1 has many advantages in addition to resolution (and one could argue that 15 MP is sufficient most of the time). The tilting screen, LEDs, AF system, viewfinder size, viewfinder display, wifi, controls, shortcuts, general ergonomics are all a step above the K-3.
That being said, the K-3 is less expensive, more compact, has a higher resolution in APS-C mode, a faster burst mode, and is a superb camera in its own right. But from the time I got the K-1, I have not used the K-3 once except for shots with the K-1 in the frame...
