Honestly, the only way to be sure you are seeing diffraction is if someone posts two pictures, one at f/4 or f/5.6; the other at f/11 or f/16. I don't think there are examples of that on this thread and possibly not on this forum. Maybe someone will give this a try.

At anything over f7.1 you are seeing diffraction as the main source of detail loss in the plane of critical focus unless you have a terrible lens. By f16, it is inescapably visible. Indeed you may wish you had not shot a landscape with so much useless depth of field, mostly more blurred that if you had used f10.

Afterward, I couldn’t believe how badly this was composed.  Wrong in so many ways.  My only excuse was rushing before the people behind stepped into the image.
