Who can explain occasional spot blur happening on otherwise sharp images? Camera & lens are like new.

One can see blur on the building in the center of an image

No blur

Hmm, it could be heat wave distortion caused by the warm sunny building vs. the cold surrounding air, though if the second shot was immediately after the first I'd expect to see it in both. Otherwise, I'd guess it's some kind of strange IBIS anomaly - Does the camera automatically set the IBIS for 85mm to work with Viltrox? Is the firmware up-to date for both the lens and camera?

Are these with the MS or ES? I've seen weird hard to explain stuff happen with the ES on occasion too.
