Please elaborate, what do we need to consider here?

If you're interesting in a better understanding of optics there are many places to start.

One could be the Optics Primer at PhotonsToPhotos.

You could go straight to the chapter on Depth of Field .

You'll find that the blur disc is affected by pupil magnification and that in turn means that common assumptions about Depth of Field, bokeh, etc. are simplistic (wrong).

For many there is no practical implication except that they understand the optics less well than they image (and pass this limited knowledge along to others in their explanations).

You might also find this related article enlightening:
