I started to type a response that explaining that I wasn't talking about exposure, I was talking about focus. Then, I set to finding examples and then I started looking at EXIF data and THEN I found out I have no idea what I am talking about. So! New question: Take a look at these two photos, both are at the same f-stop number (5.6). One looks in focus and one looks OOF. Why?
1/50
400
30mm
And:
1/50
400
30mm
I do appreciate your help
