test shot facing east in west St Louis, X2D2 +21mm f/4 at f/4/infinity (arrow middle of inf. mark), same results w/f/4-f/11.
fly by wire lens but easy to pinpoint focus manually w/clicks (it's also rare to have Santa Fe, NM clouds in St Louis but not surprised by now lol).
I believe it's the Missouri & Mississippi Rivers connecting, and forming a micro-climate above those rivers with more and different clouds based on observations living here 8 months now here. There are more clouds east towards downtown where rivers come together, making west county a cooler climate. Mostly looking east, above the rivers it's typically a cloud-soup, rather than this New Mexico-looking skyline today July 3, 25.
