Never forget: depth of field is a myth. The term is a convenient shorthand for a standard of how much defocus is acceptable, and is dependent on the ultimate size of the print or level of magnification in examination, as much as the magnification on the negative or sensor. At the highest resolution examination, even with a very small aperture, the plane of ...


The clearest image of an object is always when the object is in focus — at the plane of focus. That is, for a given lens of focal length ƒ, when the lens is positioned a distance v from the camera sensor, then an object at distance u from the lens is in focus in accordance with the thin lens approximation, ƒ-1 = u-1 + v-1.


I think you are seeing the difference in the system limits between a 20MP camera with an APS-C (23.2 X 15.4 mm) sensor that has three times the areal size of a 20MP camera with a 1" type (13.2 x 8.8 mm) sensor. You're also likely seeing the difference between a higher quality lens and a more budget friendly lens. The background in the image from the ...


With its small sensor your camera is diffraction-limited so the smaller apertures, while they give the best DoF, don't give the sharpest results. I note that the tall grass in the foreground is sharp, so it could have folled the "Intelligent Auto+" focus. And there could be a bit of atmospheric haze...
