I think you are referring to the dark spot to the left of the second
support from the left of the "Tin Man".
You shot this at ƒ9 or so. You might shoot a series of shots of the
sky (or some other well lit large plain area) from wide open to ƒ22.
Much "dirt" on your sensor can be invisible wide open, and only appear
when you stop down. Pentax manuals say to check for dust to shoot a
blue sky shot at ƒ22 with closest focus. Boy can that be a shock to
the eyeballs!
Let us know.

IF you look closely, guys, at the second of these... you can see
what I fear is some sort of
problem with the sensor... dark round spot that I got rid of in a
different frame... partly
hidden by the "tin man" - it shows up strongly in some frames and
isn't confined to one lens.
I'll upload a really obvious one later and ask for help.
