Yes, and I suspect that the correction amount depend on the focal, i.e. the longer the focal, the smaller the correction for a given value. For my DFA 100 F/2.8, I have to correct to -6. For my new Tamron 28-75 F/2.8 (just got it today), I have to correct it to -10, and it's still not sufficient ! I think that it would really be interesting to be able to cumulate the global correction (to compensate imprecise AF sensor mounting) + per lens correction. Otherwise I need twice the actual correction range. But this doesn't answer to the non operant fine tuning for the Tamron 70-200, which I can barely use on the longer end if I want good AF. Perhaps something is wrong with the correction/focal length relationship.

As explained here for the K-3, the K-1 behaves the same. To sum it up, the image is way darker when playing the movies on screen that on camera. Just look at the dark areas. You can even see the difference when using a monitor connected the the camera through the HDMI port.
I don't understand why nobody else noted that, but it clearly seems to be a bug in the codec or tags ? Just make the test that I explained there. I don't know if it's related to the REC 709 support by MOV files ? This make video recording with K-1 totally unusable.
