I walked a little with my friend in one of the St. Petersburg museums and took a few pictures just "for me", as a keepsake, without the slightest claim to "artistry".
Long exposure (~ 1/20 s), aperture almost completely open (f = 4.0@11mm). Pay attention to the text at the bottom of the diorama - it is truly clear.
I am extremely satisfied with this lens; in terms of sharpness it surpasses all wide-angle lenses that I have and have.

Sorry, the forum cuts the photos a lot, so you, alas, will not be able to evaluate the clarity of the text.
Maybe then it is better to delete this post altogether, so as not to mislead anyone?
