blur effect of lenses: new

lens comparison, old vs. new. subject: blur
=======================================================
100% details of shots taken with different lenses on two consecutive evenings, nearly the same time. Camera position differs slightly. Also a relevant difference: hardware exposure compensation was set to (1): -1 and (2) -2. I have compensated that afterwards with imaging software.

(1) 1984's fixfocus Pentax lens
vs.
(2) 2019's Sony zoom lens

The main difference I noticed is the _blur effect_.
