Can you maybe post one photo with the K-1 and FA 43mm in this thread? In the following conditions:
Av, wide open
2 sec timer, minimum ISO
Newspaper* placed around 60-80cm in front of the camera, tilted around 45 degrees
Hopefully in bright enough natural light. Maybe add EV+, if needed
Focused Manually in the middle of the newspaper in Live view, with focus peaking and digital zoom enabled.
And then one more photo with everything the same, but aperture around f3.2.
This is a simple test that can show the sharpness and DoF, and it can even show problems with decentering or other optical faults. I think this will give us an insight into just how sharp/soft the lens is, and whether it is functioning properly. And you can take the same shot with a K-5 to see if there is a difference there, if you can spare the time.
*newspaper or book or magazine. Newspaper is usually best because it is cheap, has high contrast between white paper and black text, and it is big enough to cover most of the frame and compensate even for focus problems, decentering
