For good photographs, you need good light, good composition and it all has to click, after that, lens quality plays a part.
A K-3 is more than 99 % of the forum use. Of the 1% who use more, maybe they'll use an FF and good glass. But the vast majority of K-1 owners will be advanced amateurs who will buy one because of the great price.
I bet a K-1 with a 28-105 will give me much higher IQ than a K-3 with a 16-85 or a 50-135 and 16-50 combo or whatever APS-c you choose to throw at it.
So what I'm saying is, for the advanced amateur, good glass is an option, and the K-1 will provide better resolution and low light performance, and narrower DoF than a K-3 with the best glass available. A K-1 is cheap enough to be an enthusiast camera.
A K-1 will make every one of your FF compatible lenses better. If you happily used it on a K-3, you will happily use it on a K-1.
For me this is especially meaningful for lenses like my A-400, where the quality is a little less than my 60-250. The big question will be, which is better, my A-400 gives me better IQ on a K-1 than my DA* 60-250 does on a K-3 being approximately the same focal length. I can put the 1.4 on either. A consumer prime against at DA* zoom..
SO, can you see the potential yet?
