I don't think it matters, since they are cropped to the same size anyway. More relevant would be the pixel count on the APS-C crop. as that can vary between a K5 and K3.

They're probably about the same here since it seems the shooter was standing in the same spot for both shots. Thus, fewer of the FF's available pixels were used--in fact, 1.5 times fewer--meaning that the two should have the same resolution/pixel size.

I don't know that I understand. Are you saying that you down-sampled both shots to 1080 pixels on the long side to normalize both formats to the same lower resolution and did the same for the full-resolution crops?

I would expect the results to be very, very close to each other, which they are. As a side effect, there is also a substantial pile of discarded pixels on the floor.*

Yes, I used the crop feature of the K-1. I apologize if I confused my post.

I'm going to guess these were hand held. for what it's worth, the foreground OOF area is messier in the crop vs the ff.

many hypotheses could be offered...

I would like to see the difference between 36MP FF and lets say 24MP or 15 MP OOC FF. best with High ISO to see the difference to a K3/K5. I wonder if there is a significant difference between the K1 pictures and the APS-C Cams.

Check Biz-Engineer's thread (with four pictures) for an interesting experiment on this theme.

biz-Engineers thread is not what i mean. The question is if you do not shoot in full resolution with the K-1 but in FF mode. than you use the full sensor size but not with 36 MP. This would be interesting in terms of lower file size and better IQ
