I think you'll find that the 'trick' is to use Debug mode to make the major, common, adjustment, then in-camera per-lens AF adjustment for fine tuning.I've heard on multiple occasions that the AF adjustments are not cumulative.

Not a K100D question, but perhaps the answer's in the post somewhere?

I can't believe the IR remote would have anything to do with it, but..
Don't take this the wrong way, but if this indeed proves to be a camera fault I hope this it's peculiar to your K5 and not indicative of another K5 ice-berg!
I'd like to go along with Yves suggestion, but the marks seem too consistent. I'm guessing if due to reflections you'd see changes depending which direction the cameras facing.
And I've just noticed you apparently changed the filter combo between shots, so not many variables left.
Really like your work, by the way! And as you say, this problem doesn't appear on other K5 shots in your portfolio.

Sony flagged an over-heating problem with their cameras/sensors, but it took a lot longer than 70 seconds!

Any chance it's something to do with interaction between the filters? Coking filters are known to cause purple colour casts.
The marks look like smears; I would have expected sensor issues to manifest themselves as dead straight lines?

a very simple procedure if this ever hapens to you.
if you are with held by secourity in a public place, note public place not private property call the p police & report you are beimn g witheld by persons unknown & feel in danger. the police have to respond as you reported a crime.
a security guard has no powers to touch you or hold you against your will. they can make a citizens arresy if you have commited a crime. but you must have commited a crime.
An arrestable offence is an offence where the sentence is fixed by law, for example murder because this carries a fixed sentence of life imprisonment or any other offence for which the maximum sentence that could be given to an adult is at least five years.a very simple procedure if this ever hapens to you.

Private Citizens may arrest:
Anybody who is in the act of committing an arrestable offence
Anybody with whom they have reasonable grounds for suspecting to be committing an arrestable offence
Where an arrestable offence has been committed, anybody who is guilty of the offence, or anyone whom they have reasonable grounds for suspecting.
It is important to note that when a private citizen is going to arrest anybody with whom they have reasonable grounds for suspecting to be committing an arrestable offence – they must actually have reasonable grounds for suspecting, they cannot perform a citizen’s arrest on the basis of gossip, lies, being a photographer, etc.

So John, are you saying put an existing remote with a modified swich close or attached to the camera and then trigger that with a wired or RF switch/ transmitter. Good idea but I'm not sure if I'm quite electronically up to doing the mod!
Yes, exactly that. The switch on the IR remote is a simple on/off type. I'd mount the modified IR remote in front of the camera, possibly using one of those cheap flash brackets that attachs to the base of the camera.So John, are you saying put an existing remote with a modified swich close or attached to the camera and then trigger that with a wired or RF switch/ transmitter.

The switch will be quite simple; no electronics as such.
What remote(s) are you using?

If the latter, I have, and can highly recommend, Optech straps. They genuinely make the camera/lens feel lighter and are very comfortable.
