Hi.
After upgrading the firmware to V1.30 I noticed that my pictures were "a little" out of focus . My 28-75 and 10-20mm both moved to back focus .
I had to re-calibrate all my lenses and basically all of them moved to the (+) reign.
I had my K3 from Dec 2014 and upgraded it few time by now but nothing like that happens before.

Any thoughts?

Weird, I have noticed that every once in a while my photos will appear slightly out of focus in the photo preview, but when I zoom in a little it looks just fine. Was that what you experienced, or was it just slightly out of focus even if you magnified the picture?

Noticed Back focus in all of my pictures I took that evening. I was using my 28-75/2.8 lens. since it was dark I worked in F 2.8-5.6 . at home I used my calibration chart on a tripod and noticed that the Fine Focus that was set to -5 now moved to +5 to set the FOV right in the middle.
same for all lenses - had to reset and re calibrate.

I was curious so I acquired a new focus target tool and tested my DA 18-135, DFA 50 macro, DL 55-300, and Sigma 10-20. Naturally using a tripod with SR turned off. Camera leveled in all 3 axis with image centered on the target. All lenses at maximum aperture and defocused before each test, zooms set to mid-range. I used the LCD playback zoom feature to greatly enlarge each test image.The target was very evenly lighted.

With the 1.30 release on my K-3, the zero was in sharp focus on every lens. The DOF was slightly deeper behind the target than in front; which is pretty normal.
